We look at the division of 3639716 by 879 
Let's see how many times 879 fits into 3639716.

Moving on to step 1:
When dividing 3 by 879, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 879

Going ahead to step 2:
If we divide 36 by 879, we get 0 and a remainder of 36.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 36 after subtracting 0 from 36.
Append the next digit (3) from the dividend to 36 and continue with: 363 / 879

On to step 3:
The number 879 fits into 363 0 times, leaving a remainder of 363.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 363, we get 363.
Fetch the next digit (9) from the dividend, attach it to 363 and continue: 3639 / 879

Let's proceed to step 4:
879 goes into 3639 4 times with a remainder of 123.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 123 after subtracting 3516 from 3639.
Take the next digit (7) from the dividend and append it to 123, then repeat: 1237 / 879

Let's proceed to step 5:
When dividing 1237 by 879, we get 1 with a remainder of 358.
Use 1 as the next digit of our solution. 
Result so far: 41.0
Deduct 879 from 1237 and we're left with 358.
Include the next digit (1) from the dividend after 358, then repeat: 3581 / 879

Going ahead to step 6:
The number 879 fits into 3581 4 times, leaving a remainder of 65.
Put 4 as the next digit of the answer. 
Result so far: 414.0
Deduct 3516 from 3581 and we're left with 65.
Fetch the next digit (6) from the dividend, attach it to 65 and continue: 656 / 879

Going ahead to step 7:
656 divided by 879 is 0 with a remainder of 656.
The number 0 becomes the next digit in our result. 
Result so far: 4140.0
Deduct 0 from 656 and we're left with 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Moving on to step 8:
When dividing 6560 by 879, we get 7 with a remainder of 407.
Put 7 as the next digit of the answer. 
Result so far: 4140.7
Deduct 6153 from 6560 and we're left with 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Let's proceed to step 9:
The number 879 fits into 4070 4 times, leaving a remainder of 554.
Write down 4 as next digit of the result. 
Result so far: 4140.74
Deduct 3516 from 4070 and we're left with 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Moving on to step 10:
When dividing 5540 by 879, we get 6 with a remainder of 266.
The number 6 becomes the next digit in our result. 
Result so far: 4140.746
The remainder is 266 after subtracting 5274 from 5540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

On to step 11:
When dividing 2660 by 879, we get 3 with a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 4140.7463
The remainder is 23 after subtracting 2637 from 2660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 12:
879 can be fit into 230 0 times, resulting in a remainder of 230.
The number 0 becomes the next digit in our result. 
Result so far: 4140.7463
Deduct 0 from 230 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 13:
879 goes into 2300 2 times with a remainder of 542.
Put 2 as the next digit of the answer. 
Result so far: 4140.746302
Deduct 1758 from 2300 and we're left 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.

On to step 14:
5420 divided by 879 is 6 with a remainder of 146.
Use 6 as the next digit of our solution. 
Result so far: 4140.7463026
Subtracting 5274 from 5420 leaves us with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Going ahead to step 15:
When dividing 1460 by 879, we get 1 with a remainder of 581.
The next digit of our result is 1. 
Result so far: 4140.74630261
If we take 879 away from 1460, we end up with 581.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5810, and continue the process.

Our division results in 4140.74630261 with a remaining 5.81e-07.
