We look at the division of 8503882 by 121 
Let's see how many times 121 fits into 8503882.

On to step 1:
When dividing 8 by 121, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 121

Step 2:
When dividing 85 by 121, we get 0 with a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Include the next digit (0) from the dividend after 85, then repeat: 850 / 121

Step 3:
850 divided by 121 is 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 3 after subtracting 847 from 850.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 121

Let's proceed to step 4:
If we divide 33 by 121, we get 0 and a remainder of 33.
The next digit of our result is 0. 
Result so far: 70.0
If we take 0 away from 33, we end up with 33.
Grab the next digit (8) from the dividend, add it to 33, then carry on: 338 / 121

Step 5:
The number 121 fits into 338 2 times, leaving a remainder of 96.
The number 2 becomes the next digit in our result. 
Result so far: 702.0
Subtract 242 from 338 to get 96.
Include the next digit (8) from the dividend after 96, then repeat: 968 / 121

Let's proceed to step 6:
If we divide 968 by 121, we get 8 and a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 7028.0
The remainder is 0 after subtracting 968 from 968.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 121

Moving on to step 7:
121 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 70280.0
If we subtract 0 from 2, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
When dividing 20 by 121, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 70280.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
If we divide 200 by 121, we get 1 and a remainder of 79.
Put 1 as the next digit of the answer. 
Result so far: 70280.01
If we take 121 away from 200, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 10:
The number 121 fits into 790 6 times, leaving a remainder of 64.
The next digit of our result is 6. 
Result so far: 70280.016
Subtract 726 from 790 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 11:
If we divide 640 by 121, we get 5 and a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 70280.0165
If we subtract 605 from 640, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 12:
121 goes into 350 2 times with a remainder of 108.
Record the quotient 2 as the next digit in the result. 
Result so far: 70280.01652
The remainder is 108 after subtracting 242 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Let's proceed to step 13:
The number 121 fits into 1080 8 times, leaving a remainder of 112.
Put 8 as the next digit of the answer. 
Result so far: 70280.016528
Subtracting 968 from 1080 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 14:
1120 divided by 121 is 9 with a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 70280.0165289
Subtract 1089 from 1120 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 15:
If we divide 310 by 121, we get 2 and a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 70280.01652892
The remainder is 68 after subtracting 242 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The quotient of the division is 70280.01652892, and the remainder is 6.8e-08.
