We look at the division of 39708221 by 678 
We want to divide 39708221 by 678.

Going ahead to step 1:
When dividing 3 by 678, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 678

Advancing to step 2:
The number 678 fits into 39 0 times, leaving a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Include the next digit (7) from the dividend after 39, then repeat: 397 / 678

Going ahead to step 3:
397 divided by 678 is 0 with a remainder of 397.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 397 leaves us with 397.
Fetch the next digit (0) from the dividend, attach it to 397 and continue: 3970 / 678

On to step 4:
If we divide 3970 by 678, we get 5 and a remainder of 580.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 580 after subtracting 3390 from 3970.
Include the next digit (8) from the dividend after 580, then repeat: 5808 / 678

Advancing to step 5:
The number 678 fits into 5808 8 times, leaving a remainder of 384.
Record the quotient 8 as the next digit in the result. 
Result so far: 58.0
Subtract 5424 from 5808 to get 384.
Append the next digit (2) from the dividend to 384 and continue with: 3842 / 678

Going ahead to step 6:
3842 divided by 678 is 5 with a remainder of 452.
Record the quotient 5 as the next digit in the result. 
Result so far: 585.0
The remainder is 452 after subtracting 3390 from 3842.
Grab the next digit (2) from the dividend, add it to 452, then carry on: 4522 / 678

On to step 7:
The number 678 fits into 4522 6 times, leaving a remainder of 454.
The next digit of our result is 6. 
Result so far: 5856.0
The remainder is 454 after subtracting 4068 from 4522.
Grab the next digit (1) from the dividend, add it to 454, then carry on: 4541 / 678

Advancing to step 8:
4541 divided by 678 is 6 with a remainder of 473.
Record the quotient 6 as the next digit in the result. 
Result so far: 58566.0
The remainder is 473 after subtracting 4068 from 4541.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

Let's proceed to step 9:
678 goes into 4730 6 times with a remainder of 662.
The next digit of our result is 6. 
Result so far: 58566.6
Subtracting 4068 from 4730 leaves us with 662.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

Let's proceed to step 10:
When dividing 6620 by 678, we get 9 with a remainder of 518.
The number 9 becomes the next digit in our result. 
Result so far: 58566.69
If we subtract 6102 from 6620, we get 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

Step 11:
When dividing 5180 by 678, we get 7 with a remainder of 434.
The next digit of our result is 7. 
Result so far: 58566.697
Subtracting 4746 from 5180 leaves us with 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Going ahead to step 12:
678 can be fit into 4340 6 times, resulting in a remainder of 272.
The number 6 becomes the next digit in our result. 
Result so far: 58566.6976
The remainder is 272 after subtracting 4068 from 4340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Let's proceed to step 13:
678 can be fit into 2720 4 times, resulting in a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 58566.69764
Deduct 2712 from 2720 and we're left 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.

Advancing to step 14:
The number 678 fits into 80 0 times, leaving a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 58566.69764
Subtracting 0 from 80 leaves us 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.

Advancing to step 15:
The number 678 fits into 800 1 times, leaving a remainder of 122.
The number 1 becomes the next digit in our result. 
Result so far: 58566.6976401
Subtracting 678 from 800 leaves us with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Moving on to step 16:
678 can be fit into 1220 1 times, resulting in a remainder of 542.
Record the quotient 1 as the next digit in the result. 
Result so far: 58566.69764011
If we take 678 away from 1220, we end up with 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

The final result is 58566.69764011 with a remainder of 5.42e-07.
