We look at the division of 39873878 by 704 
Our goal is to divide 39873878 by 704.

On to step 1:
If we divide 3 by 704, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 704

On to step 2:
The number 704 fits into 39 0 times, leaving a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Grab the next digit (8) from the dividend, add it to 39, then carry on: 398 / 704

Going ahead to step 3:
When dividing 398 by 704, we get 0 with a remainder of 398.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 398 to get 398.
Grab the next digit (7) from the dividend, add it to 398, then carry on: 3987 / 704

Advancing to step 4:
704 can be fit into 3987 5 times, resulting in a remainder of 467.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 467 after subtracting 3520 from 3987.
Bring next digit (3) of the dividend behind the 467 and repeat the process: 4673 / 704

On to step 5:
4673 divided by 704 is 6 with a remainder of 449.
The next digit of our result is 6. 
Result so far: 56.0
If we subtract 4224 from 4673, we get 449.
Take the next digit (8) from the dividend and append it to 449, then repeat: 4498 / 704

Let's proceed to step 6:
The number 704 fits into 4498 6 times, leaving a remainder of 274.
Write down 6 as next digit of the result. 
Result so far: 566.0
Subtract 4224 from 4498 to get 274.
Bring next digit (7) of the dividend behind the 274 and repeat the process: 2747 / 704

Step 7:
If we divide 2747 by 704, we get 3 and a remainder of 635.
Put 3 as the next digit of the answer. 
Result so far: 5663.0
If we take 2112 away from 2747, we end up with 635.
Append the next digit (8) from the dividend to 635 and continue with: 6358 / 704

On to step 8:
704 can be fit into 6358 9 times, resulting in a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 56639.0
Subtracting 6336 from 6358 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 9:
704 can be fit into 220 0 times, resulting in a remainder of 220.
Use 0 as the next digit of our solution. 
Result so far: 56639.0
If we subtract 0 from 220, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 10:
The number 704 fits into 2200 3 times, leaving a remainder of 88.
Use 3 as the next digit of our solution. 
Result so far: 56639.03
Deduct 2112 from 2200 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 11:
704 goes into 880 1 times with a remainder of 176.
Use 1 as the next digit of our solution. 
Result so far: 56639.031
If we take 704 away from 880, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 12:
704 goes into 1760 2 times with a remainder of 352.
The number 2 becomes the next digit in our result. 
Result so far: 56639.0312
The remainder is 352 after subtracting 1408 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Moving on to step 13:
704 goes into 3520 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 56639.03125
Subtracting 3520 from 3520 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 14:
When dividing 0 by 704, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 56639.03125
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 15:
When dividing 0 by 704, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 56639.03125
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 56639.03125, with a leftover of 0.0.
