We look at the division of 83039531 by 964 
The aim is to understand the frequency of 964 in 83039531.

Moving on to step 1:
If we divide 8 by 964, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 964

Step 2:
If we divide 83 by 964, we get 0 and a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Fetch the next digit (0) from the dividend, attach it to 83 and continue: 830 / 964

Going ahead to step 3:
964 can be fit into 830 0 times, resulting in a remainder of 830.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 830 and we're left with 830.
Grab the next digit (3) from the dividend, add it to 830, then carry on: 8303 / 964

Moving on to step 4:
964 can be fit into 8303 8 times, resulting in a remainder of 591.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 7712 away from 8303, we end up with 591.
Take the next digit (9) from the dividend and append it to 591, then repeat: 5919 / 964

Going ahead to step 5:
964 goes into 5919 6 times with a remainder of 135.
Write down 6 as next digit of the result. 
Result so far: 86.0
Deduct 5784 from 5919 and we're left with 135.
Grab the next digit (5) from the dividend, add it to 135, then carry on: 1355 / 964

Going ahead to step 6:
If we divide 1355 by 964, we get 1 and a remainder of 391.
The next digit of our result is 1. 
Result so far: 861.0
If we subtract 964 from 1355, we get 391.
Grab the next digit (3) from the dividend, add it to 391, then carry on: 3913 / 964

Going ahead to step 7:
The number 964 fits into 3913 4 times, leaving a remainder of 57.
The next digit of our result is 4. 
Result so far: 8614.0
Deduct 3856 from 3913 and we're left with 57.
Bring next digit (1) of the dividend behind the 57 and repeat the process: 571 / 964

On to step 8:
When dividing 571 by 964, we get 0 with a remainder of 571.
Write down 0 as next digit of the result. 
Result so far: 86140.0
The remainder is 571 after subtracting 0 from 571.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5710, and continue the process.

Going ahead to step 9:
964 goes into 5710 5 times with a remainder of 890.
Use 5 as the next digit of our solution. 
Result so far: 86140.5
If we subtract 4820 from 5710, we get 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8900, and continue the process.

On to step 10:
When dividing 8900 by 964, we get 9 with a remainder of 224.
Record the quotient 9 as the next digit in the result. 
Result so far: 86140.59
Deduct 8676 from 8900 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Moving on to step 11:
964 goes into 2240 2 times with a remainder of 312.
Write down 2 as next digit of the result. 
Result so far: 86140.592
Subtracting 1928 from 2240 leaves us with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Advancing to step 12:
964 can be fit into 3120 3 times, resulting in a remainder of 228.
Use 3 as the next digit of our solution. 
Result so far: 86140.5923
If we take 2892 away from 3120, we end up with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Advancing to step 13:
If we divide 2280 by 964, we get 2 and a remainder of 352.
The number 2 becomes the next digit in our result. 
Result so far: 86140.59232
The remainder is 352 after subtracting 1928 from 2280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Let's proceed to step 14:
964 can be fit into 3520 3 times, resulting in a remainder of 628.
The number 3 becomes the next digit in our result. 
Result so far: 86140.592323
If we take 2892 away from 3520, we end up with 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Let's proceed to step 15:
The number 964 fits into 6280 6 times, leaving a remainder of 496.
Use 6 as the next digit of our solution. 
Result so far: 86140.5923236
If we subtract 5784 from 6280, we get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Moving on to step 16:
When dividing 4960 by 964, we get 5 with a remainder of 140.
The number 5 becomes the next digit in our result. 
Result so far: 86140.59232365
Subtract 4820 from 4960 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

After the division, we end up with 86140.59232365 and a remainder of 1.4e-07.
