83889691 ÷ 635 
The aim is to understand the frequency of 635 in 83889691.

Moving on to step 1:
The number 635 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 635

Step 2:
83 divided by 635 is 0 with 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.
Append the next digit (8) from the dividend to 83 and continue with: 838 / 635

Advancing to step 3:
635 goes into 838 1 times with a remainder of 203.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 635 from 838 and we're left with 203.
Bring next digit (8) of the dividend behind the 203 and repeat the process: 2038 / 635

On to step 4:
When dividing 2038 by 635, we get 3 with a remainder of 133.
The next digit of our result is 3. 
Result so far: 13.0
The remainder is 133 after subtracting 1905 from 2038.
Include the next digit (9) from the dividend after 133, then repeat: 1339 / 635

Let's proceed to step 5:
The number 635 fits into 1339 2 times, leaving a remainder of 69.
The number 2 becomes the next digit in our result. 
Result so far: 132.0
Subtracting 1270 from 1339 leaves us with 69.
Include the next digit (6) from the dividend after 69, then repeat: 696 / 635

Advancing to step 6:
635 goes into 696 1 times with a remainder of 61.
The number 1 becomes the next digit in our result. 
Result so far: 1321.0
Subtracting 635 from 696 leaves us with 61.
Bring next digit (9) of the dividend behind the 61 and repeat the process: 619 / 635

On to step 7:
619 divided by 635 is 0 with a remainder of 619.
Record the quotient 0 as the next digit in the result. 
Result so far: 13210.0
If we subtract 0 from 619, we get 619.
Append the next digit (1) from the dividend to 619 and continue with: 6191 / 635

Moving on to step 8:
635 goes into 6191 9 times with a remainder of 476.
Put 9 as the next digit of the answer. 
Result so far: 132109.0
The remainder is 476 after subtracting 5715 from 6191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Moving on to step 9:
When dividing 4760 by 635, we get 7 with a remainder of 315.
Put 7 as the next digit of the answer. 
Result so far: 132109.7
Deduct 4445 from 4760 and we're left with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Step 10:
635 goes into 3150 4 times with a remainder of 610.
Record the quotient 4 as the next digit in the result. 
Result so far: 132109.74
The remainder is 610 after subtracting 2540 from 3150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Let's proceed to step 11:
The number 635 fits into 6100 9 times, leaving a remainder of 385.
Put 9 as the next digit of the answer. 
Result so far: 132109.749
Deduct 5715 from 6100 and we're left with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Going ahead to step 12:
The number 635 fits into 3850 6 times, leaving a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 132109.7496
If we subtract 3810 from 3850, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 13:
635 can be fit into 400 0 times, resulting in a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 132109.7496
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 14:
When dividing 4000 by 635, we get 6 with a remainder of 190.
The next digit of our result is 6. 
Result so far: 132109.749606
If we subtract 3810 from 4000, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 15:
If we divide 1900 by 635, we get 2 and a remainder of 630.
Write down 2 as next digit of the result. 
Result so far: 132109.7496062
Deduct 1270 from 1900 and we're left with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

On to step 16:
6300 divided by 635 is 9 with a remainder of 585.
The number 9 becomes the next digit in our result. 
Result so far: 132109.74960629
If we subtract 5715 from 6300, we get 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

In conclusion, the division gives 132109.74960629 with a balance of 5.85e-07.
