We look at the division of 90739395 by 121 
We're looking to find how many times 121 goes into 90739395.

Let's proceed to step 1:
The number 121 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 121

Step 2:
If we divide 90 by 121, we get 0 and a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Take the next digit (7) from the dividend and append it to 90, then repeat: 907 / 121

Going ahead to step 3:
The number 121 fits into 907 7 times, leaving a remainder of 60.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 847 from 907 to get 60.
Append the next digit (3) from the dividend to 60 and continue with: 603 / 121

Moving on to step 4:
If we divide 603 by 121, we get 4 and a remainder of 119.
The next digit of our result is 4. 
Result so far: 74.0
Subtract 484 from 603 to get 119.
Grab the next digit (9) from the dividend, add it to 119, then carry on: 1199 / 121

Moving on to step 5:
The number 121 fits into 1199 9 times, leaving a remainder of 110.
The number 9 becomes the next digit in our result. 
Result so far: 749.0
If we take 1089 away from 1199, we end up with 110.
Bring next digit (3) of the dividend behind the 110 and repeat the process: 1103 / 121

Step 6:
If we divide 1103 by 121, we get 9 and a remainder of 14.
Put 9 as the next digit of the answer. 
Result so far: 7499.0
If we subtract 1089 from 1103, we get 14.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 121

Advancing to step 7:
The number 121 fits into 149 1 times, leaving a remainder of 28.
Put 1 as the next digit of the answer. 
Result so far: 74991.0
If we subtract 121 from 149, we get 28.
Include the next digit (5) from the dividend after 28, then repeat: 285 / 121

Going ahead to step 8:
121 goes into 285 2 times with a remainder of 43.
Record the quotient 2 as the next digit in the result. 
Result so far: 749912.0
Deduct 242 from 285 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 9:
121 can be fit into 430 3 times, resulting in a remainder of 67.
Record the quotient 3 as the next digit in the result. 
Result so far: 749912.3
Deduct 363 from 430 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 10:
121 goes into 670 5 times with a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 749912.35
The remainder is 65 after subtracting 605 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 11:
121 can be fit into 650 5 times, resulting in a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 749912.355
The remainder is 45 after subtracting 605 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Our division results in 749912.355 with a remaining 0.0045.
