748949 ÷ 91 
The aim is to understand the frequency of 91 in 748949.

On to step 1:
7 divided by 91 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 91

Going ahead to step 2:
The number 91 fits into 74 0 times, leaving a remainder of 74.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 74 to get 74.
Append the next digit (8) from the dividend to 74 and continue with: 748 / 91

Going ahead to step 3:
When dividing 748 by 91, we get 8 with a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 728 away from 748, we end up with 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 91

On to step 4:
91 goes into 209 2 times with a remainder of 27.
Write down 2 as next digit of the result. 
Result so far: 82.0
Deduct 182 from 209 and we're left with 27.
Grab the next digit (4) from the dividend, add it to 27, then carry on: 274 / 91

On to step 5:
91 can be fit into 274 3 times, resulting in a remainder of 1.
The next digit of our result is 3. 
Result so far: 823.0
If we subtract 273 from 274, we get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 91

Moving on to step 6:
91 can be fit into 19 0 times, resulting in a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 8230.0
Deduct 0 from 19 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 7:
91 goes into 190 2 times with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 8230.2
Deduct 182 from 190 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 8:
If we divide 80 by 91, we get 0 and a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 8230.2
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 9:
The number 91 fits into 800 8 times, leaving a remainder of 72.
The next digit of our result is 8. 
Result so far: 8230.208
If we take 728 away from 800, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 10:
720 divided by 91 is 7 with a remainder of 83.
Write down 7 as next digit of the result. 
Result so far: 8230.2087
The remainder is 83 after subtracting 637 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Let's proceed to step 11:
The number 91 fits into 830 9 times, leaving a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 8230.20879
If we subtract 819 from 830, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 12:
The number 91 fits into 110 1 times, leaving a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 8230.208791
Subtract 91 from 110 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 13:
91 can be fit into 190 2 times, resulting in a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 8230.2087912
Subtract 182 from 190 to 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.

On to step 14:
The number 91 fits into 80 0 times, leaving a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 8230.2087912
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The quotient of the division is 8230.2087912, and the remainder is 8e-08.
