91361440 divided by 120 
The aim is to understand the frequency of 120 in 91361440.

Step 1:
If we divide 9 by 120, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 120

Advancing to step 2:
When dividing 91 by 120, 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.
Grab the next digit (3) from the dividend, add it to 91, then carry on: 913 / 120

Let's proceed to step 3:
913 divided by 120 is 7 with a remainder of 73.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 840 away from 913, we end up with 73.
Bring next digit (6) of the dividend behind the 73 and repeat the process: 736 / 120

Going ahead to step 4:
If we divide 736 by 120, we get 6 and a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 76.0
Subtracting 720 from 736 leaves us with 16.
Grab the next digit (1) from the dividend, add it to 16, then carry on: 161 / 120

On to step 5:
161 divided by 120 is 1 with a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 761.0
If we subtract 120 from 161, we get 41.
Append the next digit (4) from the dividend to 41 and continue with: 414 / 120

On to step 6:
120 can be fit into 414 3 times, resulting in a remainder of 54.
Use 3 as the next digit of our solution. 
Result so far: 7613.0
The remainder is 54 after subtracting 360 from 414.
Fetch the next digit (4) from the dividend, attach it to 54 and continue: 544 / 120

On to step 7:
When dividing 544 by 120, we get 4 with a remainder of 64.
The next digit of our result is 4. 
Result so far: 76134.0
If we take 480 away from 544, we end up with 64.
Fetch the next digit (0) from the dividend, attach it to 64 and continue: 640 / 120

Going ahead to step 8:
640 divided by 120 is 5 with a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 761345.0
Deduct 600 from 640 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
If we divide 400 by 120, we get 3 and a remainder of 40.
Write down 3 as next digit of the result. 
Result so far: 761345.3
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
400 divided by 120 is 3 with a remainder of 40.
Record the quotient 3 as the next digit in the result. 
Result so far: 761345.33
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 761345.33, with a leftover of 0.04.
