We look at the division of 31359500 by 833 
The aim is to understand the frequency of 833 in 31359500.

Going ahead to step 1:
833 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 833

Step 2:
If we divide 31 by 833, we get 0 and a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Include the next digit (3) from the dividend after 31, then repeat: 313 / 833

Moving on to step 3:
When dividing 313 by 833, we get 0 with a remainder of 313.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 313, we get 313.
Grab the next digit (5) from the dividend, add it to 313, then carry on: 3135 / 833

Going ahead to step 4:
833 goes into 3135 3 times with a remainder of 636.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 2499 from 3135 leaves us with 636.
Take the next digit (9) from the dividend and append it to 636, then repeat: 6369 / 833

Going ahead to step 5:
833 can be fit into 6369 7 times, resulting in a remainder of 538.
Write down 7 as next digit of the result. 
Result so far: 37.0
If we take 5831 away from 6369, we end up with 538.
Fetch the next digit (5) from the dividend, attach it to 538 and continue: 5385 / 833

Advancing to step 6:
When dividing 5385 by 833, we get 6 with a remainder of 387.
The next digit of our result is 6. 
Result so far: 376.0
Subtract 4998 from 5385 to get 387.
Include the next digit (0) from the dividend after 387, then repeat: 3870 / 833

Moving on to step 7:
833 goes into 3870 4 times with a remainder of 538.
Use 4 as the next digit of our solution. 
Result so far: 3764.0
Subtracting 3332 from 3870 leaves us with 538.
Bring next digit (0) of the dividend behind the 538 and repeat the process: 5380 / 833

Advancing to step 8:
833 can be fit into 5380 6 times, resulting in a remainder of 382.
Record the quotient 6 as the next digit in the result. 
Result so far: 37646.0
Deduct 4998 from 5380 and we're left with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Step 9:
The number 833 fits into 3820 4 times, leaving a remainder of 488.
Write down 4 as next digit of the result. 
Result so far: 37646.4
Deduct 3332 from 3820 and we're left with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Let's proceed to step 10:
833 can be fit into 4880 5 times, resulting in a remainder of 715.
Write down 5 as next digit of the result. 
Result so far: 37646.45
Subtract 4165 from 4880 to get 715.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7150, and continue the process.

Moving on to step 11:
The number 833 fits into 7150 8 times, leaving a remainder of 486.
Use 8 as the next digit of our solution. 
Result so far: 37646.458
If we take 6664 away from 7150, we end up with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

On to step 12:
833 can be fit into 4860 5 times, resulting in a remainder of 695.
The number 5 becomes the next digit in our result. 
Result so far: 37646.4585
The remainder is 695 after subtracting 4165 from 4860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6950, and continue the process.

On to step 13:
833 can be fit into 6950 8 times, resulting in a remainder of 286.
Record the quotient 8 as the next digit in the result. 
Result so far: 37646.45858
Deduct 6664 from 6950 and we're left with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Let's proceed to step 14:
833 can be fit into 2860 3 times, resulting in a remainder of 361.
Use 3 as the next digit of our solution. 
Result so far: 37646.458583
If we subtract 2499 from 2860, we get 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Going ahead to step 15:
The number 833 fits into 3610 4 times, leaving a remainder of 278.
Write down 4 as next digit of the result. 
Result so far: 37646.4585834
Subtract 3332 from 3610 to get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Step 16:
When dividing 2780 by 833, we get 3 with a remainder of 281.
Write down 3 as next digit of the result. 
Result so far: 37646.45858343
The remainder is 281 after subtracting 2499 from 2780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

The final result is 37646.45858343 with a remainder of 2.81e-07.
