We divide 39087739 by 678
We want to figure out the number of times 39087739 can be divided by 678.

On to step 1:
678 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 678

Moving on to step 2:
When dividing 39 by 678, we get 0 with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Take the next digit (0) from the dividend and append it to 39, then repeat: 390 / 678

Step 3:
If we divide 390 by 678, we get 0 and a remainder of 390.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 390 and we're left with 390.
Take the next digit (8) from the dividend and append it to 390, then repeat: 3908 / 678

Going ahead to step 4:
678 goes into 3908 5 times with a remainder of 518.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 3390 from 3908, we get 518.
Include the next digit (7) from the dividend after 518, then repeat: 5187 / 678

Going ahead to step 5:
If we divide 5187 by 678, we get 7 and a remainder of 441.
The next digit of our result is 7. 
Result so far: 57.0
The remainder is 441 after subtracting 4746 from 5187.
Grab the next digit (7) from the dividend, add it to 441, then carry on: 4417 / 678

Let's proceed to step 6:
678 goes into 4417 6 times with a remainder of 349.
The number 6 becomes the next digit in our result. 
Result so far: 576.0
Subtract 4068 from 4417 to get 349.
Grab the next digit (3) from the dividend, add it to 349, then carry on: 3493 / 678

On to step 7:
The number 678 fits into 3493 5 times, leaving a remainder of 103.
Put 5 as the next digit of the answer. 
Result so far: 5765.0
If we take 3390 away from 3493, we end up with 103.
Include the next digit (9) from the dividend after 103, then repeat: 1039 / 678

Moving on to step 8:
When dividing 1039 by 678, we get 1 with a remainder of 361.
The next digit of our result is 1. 
Result so far: 57651.0
Subtract 678 from 1039 to get 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Step 9:
678 can be fit into 3610 5 times, resulting in a remainder of 220.
The next digit of our result is 5. 
Result so far: 57651.5
If we subtract 3390 from 3610, 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.

Going ahead to step 10:
2200 divided by 678 is 3 with a remainder of 166.
The next digit of our result is 3. 
Result so far: 57651.53
If we take 2034 away from 2200, we end up with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Advancing to step 11:
1660 divided by 678 is 2 with a remainder of 304.
Record the quotient 2 as the next digit in the result. 
Result so far: 57651.532
Subtract 1356 from 1660 to get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Going ahead to step 12:
When dividing 3040 by 678, we get 4 with a remainder of 328.
The number 4 becomes the next digit in our result. 
Result so far: 57651.5324
The remainder is 328 after subtracting 2712 from 3040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Advancing to step 13:
If we divide 3280 by 678, we get 4 and a remainder of 568.
Use 4 as the next digit of our solution. 
Result so far: 57651.53244
The remainder is 568 after subtracting 2712 from 3280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

The quotient of the division is 57651.53244, and the remainder is 0.000568.
