We look at the division of 31072798 by 121 
Our goal is to divide 31072798 by 121.

Step 1:
121 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 121

Advancing to step 2:
When dividing 31 by 121, we get 0 with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Append the next digit (0) from the dividend to 31 and continue with: 310 / 121

Let's proceed to step 3:
121 can be fit into 310 2 times, resulting in a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 242 away from 310, we end up with 68.
Grab the next digit (7) from the dividend, add it to 68, then carry on: 687 / 121

Step 4:
If we divide 687 by 121, we get 5 and a remainder of 82.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Deduct 605 from 687 and we're left with 82.
Grab the next digit (2) from the dividend, add it to 82, then carry on: 822 / 121

Going ahead to step 5:
822 divided by 121 is 6 with a remainder of 96.
Write down 6 as next digit of the result. 
Result so far: 256.0
Subtracting 726 from 822 leaves us with 96.
Fetch the next digit (7) from the dividend, attach it to 96 and continue: 967 / 121

On to step 6:
If we divide 967 by 121, we get 7 and a remainder of 120.
Write down 7 as next digit of the result. 
Result so far: 2567.0
If we take 847 away from 967, we end up with 120.
Include the next digit (9) from the dividend after 120, then repeat: 1209 / 121

Step 7:
1209 divided by 121 is 9 with a remainder of 120.
Write down 9 as next digit of the result. 
Result so far: 25679.0
Subtracting 1089 from 1209 leaves us with 120.
Fetch the next digit (8) from the dividend, attach it to 120 and continue: 1208 / 121

Step 8:
1208 divided by 121 is 9 with a remainder of 119.
The next digit of our result is 9. 
Result so far: 256799.0
If we subtract 1089 from 1208, we get 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Step 9:
When dividing 1190 by 121, we get 9 with a remainder of 101.
Use 9 as the next digit of our solution. 
Result so far: 256799.9
Deduct 1089 from 1190 and we're left with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Let's proceed to step 10:
121 goes into 1010 8 times with a remainder of 42.
The next digit of our result is 8. 
Result so far: 256799.98
If we subtract 968 from 1010, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 11:
When dividing 420 by 121, we get 3 with a remainder of 57.
Use 3 as the next digit of our solution. 
Result so far: 256799.983
Subtract 363 from 420 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 12:
570 divided by 121 is 4 with a remainder of 86.
Put 4 as the next digit of the answer. 
Result so far: 256799.9834
Deduct 484 from 570 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 13:
121 can be fit into 860 7 times, resulting in a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 256799.98347
Deduct 847 from 860 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 14:
If we divide 130 by 121, we get 1 and a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 256799.983471
If we subtract 121 from 130, we get 9.
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 15:
The number 121 fits into 90 0 times, leaving a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 256799.983471
If we take 0 away from 90, we end up 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 16:
If we divide 900 by 121, we get 7 and a remainder of 53.
Record the quotient 7 as the next digit in the result. 
Result so far: 256799.98347107
If we take 847 away from 900, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Our division results in 256799.98347107 with a remaining 5.3e-08.
