We're dividing 91242961 by 748 
The aim is to understand the frequency of 748 in 91242961.

Going ahead to step 1:
The number 748 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 748

Moving on to step 2:
When dividing 91 by 748, we get 0 with a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Include the next digit (2) from the dividend after 91, then repeat: 912 / 748

Moving on to step 3:
912 divided by 748 is 1 with a remainder of 164.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 748 away from 912, we end up with 164.
Grab the next digit (4) from the dividend, add it to 164, then carry on: 1644 / 748

Let's proceed to step 4:
If we divide 1644 by 748, we get 2 and a remainder of 148.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtracting 1496 from 1644 leaves us with 148.
Bring next digit (2) of the dividend behind the 148 and repeat the process: 1482 / 748

Let's proceed to step 5:
748 goes into 1482 1 times with a remainder of 734.
Write down 1 as next digit of the result. 
Result so far: 121.0
If we subtract 748 from 1482, we get 734.
Include the next digit (9) from the dividend after 734, then repeat: 7349 / 748

Let's proceed to step 6:
The number 748 fits into 7349 9 times, leaving a remainder of 617.
The number 9 becomes the next digit in our result. 
Result so far: 1219.0
Deduct 6732 from 7349 and we're left with 617.
Take the next digit (6) from the dividend and append it to 617, then repeat: 6176 / 748

On to step 7:
The number 748 fits into 6176 8 times, leaving a remainder of 192.
Put 8 as the next digit of the answer. 
Result so far: 12198.0
Subtracting 5984 from 6176 leaves us with 192.
Grab the next digit (1) from the dividend, add it to 192, then carry on: 1921 / 748

Going ahead to step 8:
748 can be fit into 1921 2 times, resulting in a remainder of 425.
The next digit of our result is 2. 
Result so far: 121982.0
Subtract 1496 from 1921 to get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

On to step 9:
4250 divided by 748 is 5 with a remainder of 510.
The number 5 becomes the next digit in our result. 
Result so far: 121982.5
Deduct 3740 from 4250 and we're left with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Advancing to step 10:
When dividing 5100 by 748, we get 6 with a remainder of 612.
The next digit of our result is 6. 
Result so far: 121982.56
Subtracting 4488 from 5100 leaves us with 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Let's proceed to step 11:
When dividing 6120 by 748, we get 8 with a remainder of 136.
The next digit of our result is 8. 
Result so far: 121982.568
Subtracting 5984 from 6120 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 12:
748 goes into 1360 1 times with a remainder of 612.
The next digit of our result is 1. 
Result so far: 121982.5681
Subtract 748 from 1360 to get 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

On to step 13:
The number 748 fits into 6120 8 times, leaving a remainder of 136.
Use 8 as the next digit of our solution. 
Result so far: 121982.56818
If we take 5984 away from 6120, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 14:
The number 748 fits into 1360 1 times, leaving a remainder of 612.
Put 1 as the next digit of the answer. 
Result so far: 121982.568181
Subtract 748 from 1360 to get 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

On to step 15:
748 can be fit into 6120 8 times, resulting in a remainder of 136.
Use 8 as the next digit of our solution. 
Result so far: 121982.5681818
The remainder is 136 after subtracting 5984 from 6120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 16:
The number 748 fits into 1360 1 times, leaving a remainder of 612.
Write down 1 as next digit of the result. 
Result so far: 121982.56818181
Subtracting 748 from 1360 leaves us with 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

The final outcome is 121982.56818181, with a leftover of 6.12e-07.
