Let's divide 85428145 by 678
We want to divide 85428145 by 678.

Going ahead to step 1:
8 divided by 678 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 678

Step 2:
The number 678 fits into 85 0 times, leaving a remainder of 85.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Take the next digit (4) from the dividend and append it to 85, then repeat: 854 / 678

Going ahead to step 3:
678 can be fit into 854 1 times, resulting in a remainder of 176.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 176 after subtracting 678 from 854.
Bring next digit (2) of the dividend behind the 176 and repeat the process: 1762 / 678

On to step 4:
1762 divided by 678 is 2 with a remainder of 406.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 1356 from 1762 leaves us with 406.
Append the next digit (8) from the dividend to 406 and continue with: 4068 / 678

Advancing to step 5:
678 can be fit into 4068 6 times, resulting in a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 126.0
Subtracting 4068 from 4068 leaves us with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 678

Let's proceed to step 6:
If we divide 1 by 678, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 1260.0
If we subtract 0 from 1, we get 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 678

Advancing to step 7:
14 divided by 678 is 0 with a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 12600.0
If we subtract 0 from 14, we get 14.
Take the next digit (5) from the dividend and append it to 14, then repeat: 145 / 678

Going ahead to step 8:
145 divided by 678 is 0 with a remainder of 145.
Write down 0 as next digit of the result. 
Result so far: 126000.0
Subtracting 0 from 145 leaves us with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

On to step 9:
678 goes into 1450 2 times with a remainder of 94.
The next digit of our result is 2. 
Result so far: 126000.2
If we take 1356 away from 1450, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 10:
The number 678 fits into 940 1 times, leaving a remainder of 262.
Record the quotient 1 as the next digit in the result. 
Result so far: 126000.21
Subtract 678 from 940 to get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Step 11:
The number 678 fits into 2620 3 times, leaving a remainder of 586.
The next digit of our result is 3. 
Result so far: 126000.213
If we subtract 2034 from 2620, we get 586.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

On to step 12:
When dividing 5860 by 678, we get 8 with a remainder of 436.
Write down 8 as next digit of the result. 
Result so far: 126000.2138
Subtracting 5424 from 5860 leaves us with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Advancing to step 13:
678 goes into 4360 6 times with a remainder of 292.
Write down 6 as next digit of the result. 
Result so far: 126000.21386
If we subtract 4068 from 4360, we get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

On to step 14:
If we divide 2920 by 678, we get 4 and a remainder of 208.
The number 4 becomes the next digit in our result. 
Result so far: 126000.213864
The remainder is 208 after subtracting 2712 from 2920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

On to step 15:
2080 divided by 678 is 3 with a remainder of 46.
Use 3 as the next digit of our solution. 
Result so far: 126000.2138643
If we subtract 2034 from 2080, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 16:
When dividing 460 by 678, we get 0 with a remainder of 460.
The next digit of our result is 0. 
Result so far: 126000.2138643
If we subtract 0 from 460, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

The final result is 126000.2138643 with a remainder of 4.6e-07.
