We divide 90519045 by 121
We want to divide 90519045 by 121.

On to step 1:
The number 121 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 121

Step 2:
121 goes into 90 0 times with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Bring next digit (5) of the dividend behind the 90 and repeat the process: 905 / 121

Let's proceed to step 3:
If we divide 905 by 121, we get 7 and a remainder of 58.
The next digit of our result is 7. 
Result so far: 7.0
If we take 847 away from 905, we end up with 58.
Take the next digit (1) from the dividend and append it to 58, then repeat: 581 / 121

Going ahead to step 4:
When dividing 581 by 121, we get 4 with a remainder of 97.
Record the quotient 4 as the next digit in the result. 
Result so far: 74.0
Subtract 484 from 581 to get 97.
Append the next digit (9) from the dividend to 97 and continue with: 979 / 121

Going ahead to step 5:
121 goes into 979 8 times with a remainder of 11.
Use 8 as the next digit of our solution. 
Result so far: 748.0
If we subtract 968 from 979, we get 11.
Bring next digit (0) of the dividend behind the 11 and repeat the process: 110 / 121

Step 6:
121 goes into 110 0 times with a remainder of 110.
The next digit of our result is 0. 
Result so far: 7480.0
Deduct 0 from 110 and we're left with 110.
Grab the next digit (4) from the dividend, add it to 110, then carry on: 1104 / 121

Advancing to step 7:
1104 divided by 121 is 9 with a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 74809.0
The remainder is 15 after subtracting 1089 from 1104.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 121

Going ahead to step 8:
The number 121 fits into 155 1 times, leaving a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 748091.0
Deduct 121 from 155 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 9:
The number 121 fits into 340 2 times, leaving a remainder of 98.
The next digit of our result is 2. 
Result so far: 748091.2
If we take 242 away from 340, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 10:
980 divided by 121 is 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 748091.28
Subtract 968 from 980 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 11:
The number 121 fits into 120 0 times, leaving a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 748091.28
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 12:
When dividing 1200 by 121, we get 9 with a remainder of 111.
The next digit of our result is 9. 
Result so far: 748091.2809
The remainder is 111 after subtracting 1089 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Advancing to step 13:
The number 121 fits into 1110 9 times, leaving a remainder of 21.
The next digit of our result is 9. 
Result so far: 748091.28099
If we take 1089 away from 1110, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final outcome is 748091.28099, with a leftover of 2.1e-05.
