We're dividing 24120121 by 851 
Our goal is to divide 24120121 by 851.

On to step 1:
If we divide 2 by 851, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 851

Going ahead to step 2:
When dividing 24 by 851, we get 0 with a remainder of 24.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 24, we get 24.
Include the next digit (1) from the dividend after 24, then repeat: 241 / 851

Moving on to step 3:
241 divided by 851 is 0 with a remainder of 241.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 241 after subtracting 0 from 241.
Bring next digit (2) of the dividend behind the 241 and repeat the process: 2412 / 851

Going ahead to step 4:
2412 divided by 851 is 2 with a remainder of 710.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 1702 from 2412 leaves us with 710.
Bring next digit (0) of the dividend behind the 710 and repeat the process: 7100 / 851

Moving on to step 5:
The number 851 fits into 7100 8 times, leaving a remainder of 292.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Deduct 6808 from 7100 and we're left with 292.
Include the next digit (1) from the dividend after 292, then repeat: 2921 / 851

On to step 6:
2921 divided by 851 is 3 with a remainder of 368.
Use 3 as the next digit of our solution. 
Result so far: 283.0
Deduct 2553 from 2921 and we're left with 368.
Take the next digit (2) from the dividend and append it to 368, then repeat: 3682 / 851

Let's proceed to step 7:
When dividing 3682 by 851, we get 4 with a remainder of 278.
Put 4 as the next digit of the answer. 
Result so far: 2834.0
If we subtract 3404 from 3682, we get 278.
Take the next digit (1) from the dividend and append it to 278, then repeat: 2781 / 851

On to step 8:
851 can be fit into 2781 3 times, resulting in a remainder of 228.
Put 3 as the next digit of the answer. 
Result so far: 28343.0
Subtract 2553 from 2781 to get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Advancing to step 9:
851 can be fit into 2280 2 times, resulting in a remainder of 578.
Record the quotient 2 as the next digit in the result. 
Result so far: 28343.2
Subtracting 1702 from 2280 leaves us with 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Advancing to step 10:
If we divide 5780 by 851, we get 6 and a remainder of 674.
Record the quotient 6 as the next digit in the result. 
Result so far: 28343.26
If we subtract 5106 from 5780, we get 674.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6740, and continue the process.

Moving on to step 11:
851 can be fit into 6740 7 times, resulting in a remainder of 783.
Use 7 as the next digit of our solution. 
Result so far: 28343.267
Subtracting 5957 from 6740 leaves us with 783.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7830, and continue the process.

Going ahead to step 12:
7830 divided by 851 is 9 with a remainder of 171.
The next digit of our result is 9. 
Result so far: 28343.2679
If we take 7659 away from 7830, we end up with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Moving on to step 13:
851 can be fit into 1710 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 28343.26792
Subtracting 1702 from 1710 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 14:
80 divided by 851 is 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 28343.26792
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 15:
When dividing 800 by 851, we get 0 with a remainder of 800.
Record the quotient 0 as the next digit in the result. 
Result so far: 28343.26792
Subtract 0 from 800 to get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

The final result is 28343.26792 with a remainder of 8e-06.
