We look at the division of 3686185 by 879 
Our goal is to divide 3686185 by 879.

On to step 1:
3 divided by 879 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 879

Let's proceed to step 2:
If we divide 36 by 879, we get 0 and a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 36 after subtracting 0 from 36.
Append the next digit (8) from the dividend to 36 and continue with: 368 / 879

On to step 3:
The number 879 fits into 368 0 times, leaving a remainder of 368.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 368 and we're left with 368.
Grab the next digit (6) from the dividend, add it to 368, then carry on: 3686 / 879

Going ahead to step 4:
The number 879 fits into 3686 4 times, leaving a remainder of 170.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 3516 from 3686 leaves us with 170.
Fetch the next digit (1) from the dividend, attach it to 170 and continue: 1701 / 879

Going ahead to step 5:
If we divide 1701 by 879, we get 1 and a remainder of 822.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
If we take 879 away from 1701, we end up with 822.
Append the next digit (8) from the dividend to 822 and continue with: 8228 / 879

Advancing to step 6:
When dividing 8228 by 879, we get 9 with a remainder of 317.
The number 9 becomes the next digit in our result. 
Result so far: 419.0
Subtracting 7911 from 8228 leaves us with 317.
Include the next digit (5) from the dividend after 317, then repeat: 3175 / 879

Advancing to step 7:
If we divide 3175 by 879, we get 3 and a remainder of 538.
Write down 3 as next digit of the result. 
Result so far: 4193.0
Subtract 2637 from 3175 to get 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Step 8:
The number 879 fits into 5380 6 times, leaving a remainder of 106.
The next digit of our result is 6. 
Result so far: 4193.6
The remainder is 106 after subtracting 5274 from 5380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 9:
The number 879 fits into 1060 1 times, leaving a remainder of 181.
Write down 1 as next digit of the result. 
Result so far: 4193.61
Subtract 879 from 1060 to get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Step 10:
879 can be fit into 1810 2 times, resulting in a remainder of 52.
Use 2 as the next digit of our solution. 
Result so far: 4193.612
Subtracting 1758 from 1810 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 11:
When dividing 520 by 879, we get 0 with a remainder of 520.
The number 0 becomes the next digit in our result. 
Result so far: 4193.612
If we take 0 away from 520, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 12:
5200 divided by 879 is 5 with a remainder of 805.
Write down 5 as next digit of the result. 
Result so far: 4193.61205
Subtracting 4395 from 5200 leaves us with 805.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8050, and continue the process.

Step 13:
The number 879 fits into 8050 9 times, leaving a remainder of 139.
Put 9 as the next digit of the answer. 
Result so far: 4193.612059
The remainder is 139 after subtracting 7911 from 8050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Step 14:
879 can be fit into 1390 1 times, resulting in a remainder of 511.
Write down 1 as next digit of the result. 
Result so far: 4193.6120591
If we take 879 away from 1390, we end up with 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

Advancing to step 15:
879 can be fit into 5110 5 times, resulting in a remainder of 715.
Put 5 as the next digit of the answer. 
Result so far: 4193.61205915
If we subtract 4395 from 5110, we get 715.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7150, and continue the process.

Our division results in 4193.61205915 with a remaining 7.15e-07.
