We look at the division of 76651798 by 421 
Our goal is to divide 76651798 by 421.

Let's proceed to step 1:
If we divide 7 by 421, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 421

On to step 2:
If we divide 76 by 421, we get 0 and a remainder of 76.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 76, we get 76.
Take the next digit (6) from the dividend and append it to 76, then repeat: 766 / 421

Moving on to step 3:
The number 421 fits into 766 1 times, leaving a remainder of 345.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 421 from 766 leaves us with 345.
Take the next digit (5) from the dividend and append it to 345, then repeat: 3455 / 421

On to step 4:
The number 421 fits into 3455 8 times, leaving a remainder of 87.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtract 3368 from 3455 to get 87.
Append the next digit (1) from the dividend to 87 and continue with: 871 / 421

Moving on to step 5:
421 can be fit into 871 2 times, resulting in a remainder of 29.
Record the quotient 2 as the next digit in the result. 
Result so far: 182.0
If we subtract 842 from 871, we get 29.
Include the next digit (7) from the dividend after 29, then repeat: 297 / 421

Advancing to step 6:
If we divide 297 by 421, we get 0 and a remainder of 297.
Record the quotient 0 as the next digit in the result. 
Result so far: 1820.0
The remainder is 297 after subtracting 0 from 297.
Fetch the next digit (9) from the dividend, attach it to 297 and continue: 2979 / 421

Going ahead to step 7:
2979 divided by 421 is 7 with a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 18207.0
The remainder is 32 after subtracting 2947 from 2979.
Bring next digit (8) of the dividend behind the 32 and repeat the process: 328 / 421

Step 8:
If we divide 328 by 421, we get 0 and a remainder of 328.
Use 0 as the next digit of our solution. 
Result so far: 182070.0
Deduct 0 from 328 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Step 9:
3280 divided by 421 is 7 with a remainder of 333.
The next digit of our result is 7. 
Result so far: 182070.7
Subtract 2947 from 3280 to get 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Let's proceed to step 10:
421 can be fit into 3330 7 times, resulting in a remainder of 383.
The next digit of our result is 7. 
Result so far: 182070.77
Deduct 2947 from 3330 and we're left with 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

The final result is 182070.77 with a remainder of 0.383.
