We divide 120574 by 91
The aim is to understand the frequency of 91 in 120574.

Advancing to step 1:
If we divide 1 by 91, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 91

Let's proceed to step 2:
When dividing 12 by 91, we get 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 91

On to step 3:
If we divide 120 by 91, we get 1 and a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 91 from 120 to get 29.
Fetch the next digit (5) from the dividend, attach it to 29 and continue: 295 / 91

Advancing to step 4:
The number 91 fits into 295 3 times, leaving a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we subtract 273 from 295, we get 22.
Append the next digit (7) from the dividend to 22 and continue with: 227 / 91

Advancing to step 5:
The number 91 fits into 227 2 times, leaving a remainder of 45.
Use 2 as the next digit of our solution. 
Result so far: 132.0
If we take 182 away from 227, we end up with 45.
Fetch the next digit (4) from the dividend, attach it to 45 and continue: 454 / 91

Step 6:
91 goes into 454 4 times with a remainder of 90.
The number 4 becomes the next digit in our result. 
Result so far: 1324.0
Subtracting 364 from 454 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 7:
The number 91 fits into 900 9 times, leaving a remainder of 81.
Write down 9 as next digit of the result. 
Result so far: 1324.9
Subtracting 819 from 900 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 8:
If we divide 810 by 91, we get 8 and a remainder of 82.
The next digit of our result is 8. 
Result so far: 1324.98
Deduct 728 from 810 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 9:
The number 91 fits into 820 9 times, leaving a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 1324.989
Deduct 819 from 820 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 10:
The number 91 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 1324.989
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 11:
If we divide 100 by 91, we get 1 and a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1324.98901
The remainder is 9 after subtracting 91 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 12:
91 can be fit into 90 0 times, resulting in a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 1324.98901
Subtracting 0 from 90 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 13:
91 goes into 900 9 times with a remainder of 81.
The number 9 becomes the next digit in our result. 
Result so far: 1324.9890109
The remainder is 81 after subtracting 819 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 14:
810 divided by 91 is 8 with a remainder of 82.
The next digit of our result is 8. 
Result so far: 1324.98901098
Deduct 728 from 810 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

The quotient of the division is 1324.98901098, and the remainder is 8.2e-08.
