We divide 83658626 by 872
The aim is to understand the frequency of 872 in 83658626.

Going ahead to step 1:
When dividing 8 by 872, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 872

Advancing to step 2:
The number 872 fits into 83 0 times, leaving a remainder of 83.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 83 and we're left with 83.
Include the next digit (6) from the dividend after 83, then repeat: 836 / 872

Moving on to step 3:
836 divided by 872 is 0 with a remainder of 836.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 836 leaves us with 836.
Append the next digit (5) from the dividend to 836 and continue with: 8365 / 872

On to step 4:
The number 872 fits into 8365 9 times, leaving a remainder of 517.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 7848 from 8365 to get 517.
Bring next digit (8) of the dividend behind the 517 and repeat the process: 5178 / 872

Let's proceed to step 5:
872 can be fit into 5178 5 times, resulting in a remainder of 818.
Use 5 as the next digit of our solution. 
Result so far: 95.0
Deduct 4360 from 5178 and we're left with 818.
Append the next digit (6) from the dividend to 818 and continue with: 8186 / 872

On to step 6:
872 goes into 8186 9 times with a remainder of 338.
Put 9 as the next digit of the answer. 
Result so far: 959.0
If we subtract 7848 from 8186, we get 338.
Grab the next digit (2) from the dividend, add it to 338, then carry on: 3382 / 872

Advancing to step 7:
If we divide 3382 by 872, we get 3 and a remainder of 766.
The number 3 becomes the next digit in our result. 
Result so far: 9593.0
If we subtract 2616 from 3382, we get 766.
Fetch the next digit (6) from the dividend, attach it to 766 and continue: 7666 / 872

Let's proceed to step 8:
872 goes into 7666 8 times with a remainder of 690.
Record the quotient 8 as the next digit in the result. 
Result so far: 95938.0
Subtract 6976 from 7666 to get 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

On to step 9:
When dividing 6900 by 872, we get 7 with a remainder of 796.
The next digit of our result is 7. 
Result so far: 95938.7
Deduct 6104 from 6900 and we're left with 796.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7960, and continue the process.

Moving on to step 10:
When dividing 7960 by 872, we get 9 with a remainder of 112.
Put 9 as the next digit of the answer. 
Result so far: 95938.79
The remainder is 112 after subtracting 7848 from 7960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 11:
1120 divided by 872 is 1 with a remainder of 248.
The next digit of our result is 1. 
Result so far: 95938.791
The remainder is 248 after subtracting 872 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Advancing to step 12:
If we divide 2480 by 872, we get 2 and a remainder of 736.
Put 2 as the next digit of the answer. 
Result so far: 95938.7912
If we subtract 1744 from 2480, we get 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Moving on to step 13:
The number 872 fits into 7360 8 times, leaving a remainder of 384.
Put 8 as the next digit of the answer. 
Result so far: 95938.79128
The remainder is 384 after subtracting 6976 from 7360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 14:
The number 872 fits into 3840 4 times, leaving a remainder of 352.
Use 4 as the next digit of our solution. 
Result so far: 95938.791284
The remainder is 352 after subtracting 3488 from 3840.
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 15:
When dividing 3520 by 872, we get 4 with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 95938.7912844
If we take 3488 away from 3520, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 95938.7912844 and a remainder of 3.2e-07.
