We're dividing 3900067 by 888 
We want to figure out the number of times 3900067 can be divided by 888.

Step 1:
If we divide 3 by 888, 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.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 888

Step 2:
888 can be fit into 39 0 times, resulting in 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.
Grab the next digit (0) from the dividend, add it to 39, then carry on: 390 / 888

Advancing to step 3:
888 can be fit into 390 0 times, resulting in a remainder of 390.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 390 and we're left with 390.
Fetch the next digit (0) from the dividend, attach it to 390 and continue: 3900 / 888

Advancing to step 4:
888 can be fit into 3900 4 times, resulting in a remainder of 348.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 3552 away from 3900, we end up with 348.
Include the next digit (0) from the dividend after 348, then repeat: 3480 / 888

On to step 5:
3480 divided by 888 is 3 with a remainder of 816.
The next digit of our result is 3. 
Result so far: 43.0
If we take 2664 away from 3480, we end up with 816.
Append the next digit (6) from the dividend to 816 and continue with: 8166 / 888

Going ahead to step 6:
If we divide 8166 by 888, we get 9 and a remainder of 174.
Use 9 as the next digit of our solution. 
Result so far: 439.0
The remainder is 174 after subtracting 7992 from 8166.
Include the next digit (7) from the dividend after 174, then repeat: 1747 / 888

Moving on to step 7:
888 goes into 1747 1 times with a remainder of 859.
The next digit of our result is 1. 
Result so far: 4391.0
The remainder is 859 after subtracting 888 from 1747.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8590, and continue the process.

Step 8:
8590 divided by 888 is 9 with a remainder of 598.
Write down 9 as next digit of the result. 
Result so far: 4391.9
Subtracting 7992 from 8590 leaves us with 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

On to step 9:
5980 divided by 888 is 6 with a remainder of 652.
Put 6 as the next digit of the answer. 
Result so far: 4391.96
Deduct 5328 from 5980 and we're left with 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

On to step 10:
If we divide 6520 by 888, we get 7 and a remainder of 304.
The next digit of our result is 7. 
Result so far: 4391.967
Subtract 6216 from 6520 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.

Step 11:
3040 divided by 888 is 3 with a remainder of 376.
Record the quotient 3 as the next digit in the result. 
Result so far: 4391.9673
The remainder is 376 after subtracting 2664 from 3040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Step 12:
888 can be fit into 3760 4 times, resulting in a remainder of 208.
The next digit of our result is 4. 
Result so far: 4391.96734
The remainder is 208 after subtracting 3552 from 3760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Step 13:
When dividing 2080 by 888, we get 2 with a remainder of 304.
The next digit of our result is 2. 
Result so far: 4391.967342
Subtract 1776 from 2080 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.

Step 14:
888 can be fit into 3040 3 times, resulting in a remainder of 376.
The number 3 becomes the next digit in our result. 
Result so far: 4391.9673423
If we subtract 2664 from 3040, we get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Step 15:
888 goes into 3760 4 times with a remainder of 208.
Put 4 as the next digit of the answer. 
Result so far: 4391.96734234
Subtract 3552 from 3760 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

The final result is 4391.96734234 with a remainder of 2.08e-07.
