80667136 divided by 629 
The aim is to understand the frequency of 629 in 80667136.

On to step 1:
629 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 629

On to step 2:
80 divided by 629 is 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Append the next digit (6) from the dividend to 80 and continue with: 806 / 629

On to step 3:
806 divided by 629 is 1 with a remainder of 177.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 629 from 806 to get 177.
Fetch the next digit (6) from the dividend, attach it to 177 and continue: 1776 / 629

Step 4:
If we divide 1776 by 629, we get 2 and a remainder of 518.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 1258 from 1776 leaves us with 518.
Append the next digit (7) from the dividend to 518 and continue with: 5187 / 629

Going ahead to step 5:
If we divide 5187 by 629, we get 8 and a remainder of 155.
Write down 8 as next digit of the result. 
Result so far: 128.0
Subtract 5032 from 5187 to get 155.
Fetch the next digit (1) from the dividend, attach it to 155 and continue: 1551 / 629

Moving on to step 6:
1551 divided by 629 is 2 with a remainder of 293.
The next digit of our result is 2. 
Result so far: 1282.0
Deduct 1258 from 1551 and we're left with 293.
Bring next digit (3) of the dividend behind the 293 and repeat the process: 2933 / 629

Moving on to step 7:
629 can be fit into 2933 4 times, resulting in a remainder of 417.
Write down 4 as next digit of the result. 
Result so far: 12824.0
Deduct 2516 from 2933 and we're left with 417.
Grab the next digit (6) from the dividend, add it to 417, then carry on: 4176 / 629

Moving on to step 8:
If we divide 4176 by 629, we get 6 and a remainder of 402.
Write down 6 as next digit of the result. 
Result so far: 128246.0
Subtracting 3774 from 4176 leaves us with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

On to step 9:
629 can be fit into 4020 6 times, resulting in a remainder of 246.
Put 6 as the next digit of the answer. 
Result so far: 128246.6
If we take 3774 away from 4020, we end up with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Going ahead to step 10:
2460 divided by 629 is 3 with a remainder of 573.
The next digit of our result is 3. 
Result so far: 128246.63
If we subtract 1887 from 2460, we get 573.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5730, and continue the process.

On to step 11:
5730 divided by 629 is 9 with a remainder of 69.
The number 9 becomes the next digit in our result. 
Result so far: 128246.639
If we take 5661 away from 5730, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 12:
629 can be fit into 690 1 times, resulting in a remainder of 61.
The next digit of our result is 1. 
Result so far: 128246.6391
Subtracting 629 from 690 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 13:
If we divide 610 by 629, we get 0 and a remainder of 610.
Write down 0 as next digit of the result. 
Result so far: 128246.6391
Subtracting 0 from 610 leaves us with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

On to step 14:
If we divide 6100 by 629, we get 9 and a remainder of 439.
The number 9 becomes the next digit in our result. 
Result so far: 128246.639109
Subtracting 5661 from 6100 leaves us with 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

Let's proceed to step 15:
The number 629 fits into 4390 6 times, leaving a remainder of 616.
Put 6 as the next digit of the answer. 
Result so far: 128246.6391096
Subtracting 3774 from 4390 leaves us with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Moving on to step 16:
The number 629 fits into 6160 9 times, leaving a remainder of 499.
The number 9 becomes the next digit in our result. 
Result so far: 128246.63910969
The remainder is 499 after subtracting 5661 from 6160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4990, and continue the process.

The final outcome is 128246.63910969, with a leftover of 4.99e-07.
