Let's divide 78839432 by 451
Our goal is to divide 78839432 by 451.

Moving on to step 1:
7 divided by 451 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 451

Advancing to step 2:
When dividing 78 by 451, we get 0 with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Fetch the next digit (8) from the dividend, attach it to 78 and continue: 788 / 451

Step 3:
When dividing 788 by 451, we get 1 with a remainder of 337.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 451 from 788 and we're left with 337.
Fetch the next digit (3) from the dividend, attach it to 337 and continue: 3373 / 451

Let's proceed to step 4:
When dividing 3373 by 451, we get 7 with a remainder of 216.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtracting 3157 from 3373 leaves us with 216.
Include the next digit (9) from the dividend after 216, then repeat: 2169 / 451

Going ahead to step 5:
2169 divided by 451 is 4 with a remainder of 365.
The next digit of our result is 4. 
Result so far: 174.0
If we take 1804 away from 2169, we end up with 365.
Bring next digit (4) of the dividend behind the 365 and repeat the process: 3654 / 451

Advancing to step 6:
451 goes into 3654 8 times with a remainder of 46.
Use 8 as the next digit of our solution. 
Result so far: 1748.0
The remainder is 46 after subtracting 3608 from 3654.
Append the next digit (3) from the dividend to 46 and continue with: 463 / 451

Going ahead to step 7:
451 can be fit into 463 1 times, resulting in a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 17481.0
Deduct 451 from 463 and we're left with 12.
Fetch the next digit (2) from the dividend, attach it to 12 and continue: 122 / 451

Going ahead to step 8:
The number 451 fits into 122 0 times, leaving a remainder of 122.
Put 0 as the next digit of the answer. 
Result so far: 174810.0
Subtract 0 from 122 to get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

On to step 9:
451 can be fit into 1220 2 times, resulting in a remainder of 318.
Put 2 as the next digit of the answer. 
Result so far: 174810.2
If we take 902 away from 1220, we end up with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Moving on to step 10:
3180 divided by 451 is 7 with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 174810.27
Subtract 3157 from 3180 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 11:
451 can be fit into 230 0 times, resulting in a remainder of 230.
The next digit of our result is 0. 
Result so far: 174810.27
If we take 0 away from 230, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 12:
When dividing 2300 by 451, we get 5 with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 174810.2705
Subtract 2255 from 2300 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 13:
451 can be fit into 450 0 times, resulting in a remainder of 450.
The number 0 becomes the next digit in our result. 
Result so far: 174810.2705
The remainder is 450 after subtracting 0 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Moving on to step 14:
The number 451 fits into 4500 9 times, leaving a remainder of 441.
Record the quotient 9 as the next digit in the result. 
Result so far: 174810.270509
If we subtract 4059 from 4500, we get 441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

Going ahead to step 15:
4410 divided by 451 is 9 with a remainder of 351.
Write down 9 as next digit of the result. 
Result so far: 174810.2705099
Deduct 4059 from 4410 and we're left with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

After the division, we end up with 174810.2705099 and a remainder of 3.51e-06.
