We divide 91747398 by 880
The aim is to understand the frequency of 880 in 91747398.

Advancing to step 1:
9 divided by 880 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 880

Moving on to step 2:
91 divided by 880 is 0 with a remainder of 91.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 91 to get 91.
Bring next digit (7) of the dividend behind the 91 and repeat the process: 917 / 880

Going ahead to step 3:
When dividing 917 by 880, we get 1 with a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 880 from 917 to get 37.
Take the next digit (4) from the dividend and append it to 37, then repeat: 374 / 880

Advancing to step 4:
The number 880 fits into 374 0 times, leaving a remainder of 374.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 374, we get 374.
Append the next digit (7) from the dividend to 374 and continue with: 3747 / 880

On to step 5:
The number 880 fits into 3747 4 times, leaving a remainder of 227.
Write down 4 as next digit of the result. 
Result so far: 104.0
If we take 3520 away from 3747, we end up with 227.
Grab the next digit (3) from the dividend, add it to 227, then carry on: 2273 / 880

Advancing to step 6:
2273 divided by 880 is 2 with a remainder of 513.
Put 2 as the next digit of the answer. 
Result so far: 1042.0
If we subtract 1760 from 2273, we get 513.
Bring next digit (9) of the dividend behind the 513 and repeat the process: 5139 / 880

On to step 7:
880 goes into 5139 5 times with a remainder of 739.
Put 5 as the next digit of the answer. 
Result so far: 10425.0
The remainder is 739 after subtracting 4400 from 5139.
Include the next digit (8) from the dividend after 739, then repeat: 7398 / 880

Step 8:
880 can be fit into 7398 8 times, resulting in a remainder of 358.
The number 8 becomes the next digit in our result. 
Result so far: 104258.0
If we subtract 7040 from 7398, we get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

On to step 9:
If we divide 3580 by 880, we get 4 and a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 104258.4
Subtract 3520 from 3580 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 10:
880 can be fit into 600 0 times, resulting in a remainder of 600.
Write down 0 as next digit of the result. 
Result so far: 104258.4
Subtracting 0 from 600 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 11:
6000 divided by 880 is 6 with a remainder of 720.
The next digit of our result is 6. 
Result so far: 104258.406
If we take 5280 away from 6000, we end up with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Advancing to step 12:
The number 880 fits into 7200 8 times, leaving a remainder of 160.
The number 8 becomes the next digit in our result. 
Result so far: 104258.4068
If we take 7040 away from 7200, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 13:
880 goes into 1600 1 times with a remainder of 720.
Use 1 as the next digit of our solution. 
Result so far: 104258.40681
The remainder is 720 after subtracting 880 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Step 14:
The number 880 fits into 7200 8 times, leaving a remainder of 160.
Put 8 as the next digit of the answer. 
Result so far: 104258.406818
If we subtract 7040 from 7200, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 15:
1600 divided by 880 is 1 with a remainder of 720.
The next digit of our result is 1. 
Result so far: 104258.4068181
The remainder is 720 after subtracting 880 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Going ahead to step 16:
880 goes into 7200 8 times with a remainder of 160.
The next digit of our result is 8. 
Result so far: 104258.40681818
Subtracting 7040 from 7200 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final outcome is 104258.40681818, with a leftover of 1.6e-07.
