Let's divide 91275720 by 626
The aim is to understand the frequency of 626 in 91275720.

Advancing to step 1:
If we divide 9 by 626, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 626

Advancing to step 2:
The number 626 fits into 91 0 times, leaving a remainder of 91.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 91 leaves us with 91.
Bring next digit (2) of the dividend behind the 91 and repeat the process: 912 / 626

On to step 3:
912 divided by 626 is 1 with a remainder of 286.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 626 from 912 to get 286.
Append the next digit (7) from the dividend to 286 and continue with: 2867 / 626

Going ahead to step 4:
When dividing 2867 by 626, we get 4 with a remainder of 363.
The next digit of our result is 4. 
Result so far: 14.0
The remainder is 363 after subtracting 2504 from 2867.
Take the next digit (5) from the dividend and append it to 363, then repeat: 3635 / 626

On to step 5:
When dividing 3635 by 626, we get 5 with a remainder of 505.
The next digit of our result is 5. 
Result so far: 145.0
Subtract 3130 from 3635 to get 505.
Take the next digit (7) from the dividend and append it to 505, then repeat: 5057 / 626

Let's proceed to step 6:
The number 626 fits into 5057 8 times, leaving a remainder of 49.
Put 8 as the next digit of the answer. 
Result so far: 1458.0
Subtract 5008 from 5057 to get 49.
Append the next digit (2) from the dividend to 49 and continue with: 492 / 626

Step 7:
If we divide 492 by 626, we get 0 and a remainder of 492.
Record the quotient 0 as the next digit in the result. 
Result so far: 14580.0
If we subtract 0 from 492, we get 492.
Append the next digit (0) from the dividend to 492 and continue with: 4920 / 626

Going ahead to step 8:
4920 divided by 626 is 7 with a remainder of 538.
Use 7 as the next digit of our solution. 
Result so far: 145807.0
The remainder is 538 after subtracting 4382 from 4920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Let's proceed to step 9:
The number 626 fits into 5380 8 times, leaving a remainder of 372.
The next digit of our result is 8. 
Result so far: 145807.8
Subtract 5008 from 5380 to get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Advancing to step 10:
If we divide 3720 by 626, we get 5 and a remainder of 590.
Put 5 as the next digit of the answer. 
Result so far: 145807.85
The remainder is 590 after subtracting 3130 from 3720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Moving on to step 11:
626 goes into 5900 9 times with a remainder of 266.
Record the quotient 9 as the next digit in the result. 
Result so far: 145807.859
The remainder is 266 after subtracting 5634 from 5900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Going ahead to step 12:
626 goes into 2660 4 times with a remainder of 156.
The next digit of our result is 4. 
Result so far: 145807.8594
Deduct 2504 from 2660 and we're left with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Advancing to step 13:
626 can be fit into 1560 2 times, resulting in a remainder of 308.
Use 2 as the next digit of our solution. 
Result so far: 145807.85942
Subtracting 1252 from 1560 leaves us with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Advancing to step 14:
626 goes into 3080 4 times with a remainder of 576.
Record the quotient 4 as the next digit in the result. 
Result so far: 145807.859424
Subtract 2504 from 3080 to get 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Moving on to step 15:
The number 626 fits into 5760 9 times, leaving a remainder of 126.
Put 9 as the next digit of the answer. 
Result so far: 145807.8594249
Deduct 5634 from 5760 and we're left with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 16:
If we divide 1260 by 626, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 145807.85942492
If we subtract 1252 from 1260, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 145807.85942492 and a remainder of 8e-09.
