Let's divide 87975943 by 121
We want to divide 87975943 by 121.

On to step 1:
121 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 121

Let's proceed to step 2:
121 can be fit into 87 0 times, resulting in a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Fetch the next digit (9) from the dividend, attach it to 87 and continue: 879 / 121

Step 3:
879 divided by 121 is 7 with a remainder of 32.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 847 from 879, we get 32.
Append the next digit (7) from the dividend to 32 and continue with: 327 / 121

Step 4:
121 goes into 327 2 times with a remainder of 85.
The number 2 becomes the next digit in our result. 
Result so far: 72.0
Deduct 242 from 327 and we're left with 85.
Take the next digit (5) from the dividend and append it to 85, then repeat: 855 / 121

Moving on to step 5:
121 can be fit into 855 7 times, resulting in a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 727.0
If we take 847 away from 855, we end up with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 121

Let's proceed to step 6:
121 can be fit into 89 0 times, resulting in a remainder of 89.
Record the quotient 0 as the next digit in the result. 
Result so far: 7270.0
Subtracting 0 from 89 leaves us with 89.
Append the next digit (4) from the dividend to 89 and continue with: 894 / 121

Advancing to step 7:
When dividing 894 by 121, we get 7 with a remainder of 47.
Record the quotient 7 as the next digit in the result. 
Result so far: 72707.0
Subtracting 847 from 894 leaves us with 47.
Append the next digit (3) from the dividend to 47 and continue with: 473 / 121

Advancing to step 8:
The number 121 fits into 473 3 times, leaving a remainder of 110.
The number 3 becomes the next digit in our result. 
Result so far: 727073.0
Subtract 363 from 473 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 9:
When dividing 1100 by 121, we get 9 with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 727073.9
Deduct 1089 from 1100 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 10:
121 can be fit into 110 0 times, resulting in a remainder of 110.
Use 0 as the next digit of our solution. 
Result so far: 727073.9
Subtracting 0 from 110 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 11:
1100 divided by 121 is 9 with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 727073.909
Subtracting 1089 from 1100 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 12:
121 goes into 110 0 times with a remainder of 110.
The number 0 becomes the next digit in our result. 
Result so far: 727073.909
If we take 0 away from 110, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 13:
The number 121 fits into 1100 9 times, leaving a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 727073.90909
Deduct 1089 from 1100 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 14:
If we divide 110 by 121, we get 0 and a remainder of 110.
Put 0 as the next digit of the answer. 
Result so far: 727073.90909
Deduct 0 from 110 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 15:
When dividing 1100 by 121, we get 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 727073.9090909
Deduct 1089 from 1100 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 16:
121 goes into 110 0 times with a remainder of 110.
Write down 0 as next digit of the result. 
Result so far: 727073.9090909
The remainder is 110 after subtracting 0 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

The final result is 727073.9090909 with a remainder of 1.1e-07.
