We're dividing 13962613 by 879 
We want to figure out the number of times 13962613 can be divided by 879.

Let's proceed to step 1:
1 divided by 879 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 879

On to step 2:
The number 879 fits into 13 0 times, leaving a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 879

Step 3:
The number 879 fits into 139 0 times, leaving a remainder of 139.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 139, we end up with 139.
Grab the next digit (6) from the dividend, add it to 139, then carry on: 1396 / 879

Moving on to step 4:
879 goes into 1396 1 times with a remainder of 517.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 517 after subtracting 879 from 1396.
Include the next digit (2) from the dividend after 517, then repeat: 5172 / 879

Step 5:
879 goes into 5172 5 times with a remainder of 777.
The next digit of our result is 5. 
Result so far: 15.0
Subtract 4395 from 5172 to get 777.
Append the next digit (6) from the dividend to 777 and continue with: 7776 / 879

Advancing to step 6:
879 can be fit into 7776 8 times, resulting in a remainder of 744.
Put 8 as the next digit of the answer. 
Result so far: 158.0
Deduct 7032 from 7776 and we're left with 744.
Bring next digit (1) of the dividend behind the 744 and repeat the process: 7441 / 879

Advancing to step 7:
The number 879 fits into 7441 8 times, leaving a remainder of 409.
Put 8 as the next digit of the answer. 
Result so far: 1588.0
Deduct 7032 from 7441 and we're left with 409.
Bring next digit (3) of the dividend behind the 409 and repeat the process: 4093 / 879

On to step 8:
The number 879 fits into 4093 4 times, leaving a remainder of 577.
Record the quotient 4 as the next digit in the result. 
Result so far: 15884.0
If we subtract 3516 from 4093, we get 577.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5770, and continue the process.

Let's proceed to step 9:
879 can be fit into 5770 6 times, resulting in a remainder of 496.
The number 6 becomes the next digit in our result. 
Result so far: 15884.6
Deduct 5274 from 5770 and we're left with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

On to step 10:
879 goes into 4960 5 times with a remainder of 565.
Record the quotient 5 as the next digit in the result. 
Result so far: 15884.65
If we take 4395 away from 4960, we end up with 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

Moving on to step 11:
If we divide 5650 by 879, we get 6 and a remainder of 376.
Record the quotient 6 as the next digit in the result. 
Result so far: 15884.656
If we subtract 5274 from 5650, 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 12:
879 goes into 3760 4 times with a remainder of 244.
Record the quotient 4 as the next digit in the result. 
Result so far: 15884.6564
Subtract 3516 from 3760 to get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Moving on to step 13:
879 can be fit into 2440 2 times, resulting in a remainder of 682.
The number 2 becomes the next digit in our result. 
Result so far: 15884.65642
Deduct 1758 from 2440 and we're left with 682.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6820, and continue the process.

Advancing to step 14:
879 goes into 6820 7 times with a remainder of 667.
The next digit of our result is 7. 
Result so far: 15884.656427
Deduct 6153 from 6820 and we're left with 667.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6670, and continue the process.

Moving on to step 15:
879 can be fit into 6670 7 times, resulting in a remainder of 517.
Record the quotient 7 as the next digit in the result. 
Result so far: 15884.6564277
Deduct 6153 from 6670 and we're left with 517.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5170, and continue the process.

The final result is 15884.6564277 with a remainder of 5.17e-06.
