We look at the division of 91389865 by 120 
We want to figure out the number of times 91389865 can be divided by 120.

Let's proceed to step 1:
120 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 120

On to step 2:
91 divided by 120 is 0 with a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 91 leaves us with 91.
Include the next digit (3) from the dividend after 91, then repeat: 913 / 120

Going ahead to step 3:
The number 120 fits into 913 7 times, leaving a remainder of 73.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 840 away from 913, we end up with 73.
Include the next digit (8) from the dividend after 73, then repeat: 738 / 120

Going ahead to step 4:
120 goes into 738 6 times with a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 76.0
Subtract 720 from 738 to get 18.
Bring next digit (9) of the dividend behind the 18 and repeat the process: 189 / 120

Advancing to step 5:
189 divided by 120 is 1 with a remainder of 69.
Use 1 as the next digit of our solution. 
Result so far: 761.0
Subtract 120 from 189 to get 69.
Grab the next digit (8) from the dividend, add it to 69, then carry on: 698 / 120

Moving on to step 6:
698 divided by 120 is 5 with a remainder of 98.
The number 5 becomes the next digit in our result. 
Result so far: 7615.0
Subtracting 600 from 698 leaves us with 98.
Append the next digit (6) from the dividend to 98 and continue with: 986 / 120

Step 7:
If we divide 986 by 120, we get 8 and a remainder of 26.
The number 8 becomes the next digit in our result. 
Result so far: 76158.0
If we take 960 away from 986, we end up with 26.
Append the next digit (5) from the dividend to 26 and continue with: 265 / 120

Moving on to step 8:
120 can be fit into 265 2 times, resulting in a remainder of 25.
The number 2 becomes the next digit in our result. 
Result so far: 761582.0
If we take 240 away from 265, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 9:
If we divide 250 by 120, we get 2 and a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 761582.2
Subtracting 240 from 250 leaves us 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.

On to step 10:
When dividing 100 by 120, we get 0 with a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 761582.2
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 11:
When dividing 1000 by 120, we get 8 with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 761582.208
Subtracting 960 from 1000 leaves us 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.

Let's proceed to step 12:
400 divided by 120 is 3 with a remainder of 40.
The next digit of our result is 3. 
Result so far: 761582.2083
Subtracting 360 from 400 leaves us 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.

Let's proceed to step 13:
400 divided by 120 is 3 with a remainder of 40.
Write down 3 as next digit of the result. 
Result so far: 761582.20833
If we take 360 away from 400, we end up 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 result is 761582.20833 with a remainder of 4e-05.
