879983 ÷ 87 
We want to figure out the number of times 879983 can be divided by 87.

Going ahead to step 1:
If we divide 8 by 87, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 87

Going ahead to step 2:
The number 87 fits into 87 1 times, leaving a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 87 from 87 leaves us with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 87

On to step 3:
The number 87 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 9, we end up with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 87

On to step 4:
87 goes into 99 1 times with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 101.0
If we take 87 away from 99, we end up with 12.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 87

Going ahead to step 5:
87 goes into 128 1 times with a remainder of 41.
Write down 1 as next digit of the result. 
Result so far: 1011.0
The remainder is 41 after subtracting 87 from 128.
Include the next digit (3) from the dividend after 41, then repeat: 413 / 87

Moving on to step 6:
413 divided by 87 is 4 with a remainder of 65.
Write down 4 as next digit of the result. 
Result so far: 10114.0
Subtracting 348 from 413 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 7:
The number 87 fits into 650 7 times, leaving a remainder of 41.
Record the quotient 7 as the next digit in the result. 
Result so far: 10114.7
If we take 609 away from 650, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 8:
87 goes into 410 4 times with a remainder of 62.
The number 4 becomes the next digit in our result. 
Result so far: 10114.74
Deduct 348 from 410 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 9:
The number 87 fits into 620 7 times, leaving a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 10114.747
Subtract 609 from 620 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 10:
87 goes into 110 1 times with a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 10114.7471
Deduct 87 from 110 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 11:
The number 87 fits into 230 2 times, leaving a remainder of 56.
Record the quotient 2 as the next digit in the result. 
Result so far: 10114.74712
If we take 174 away from 230, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 12:
87 goes into 560 6 times with a remainder of 38.
Record the quotient 6 as the next digit in the result. 
Result so far: 10114.747126
Subtract 522 from 560 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 13:
When dividing 380 by 87, we get 4 with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 10114.7471264
Subtracting 348 from 380 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 14:
87 goes into 320 3 times with a remainder of 59.
Record the quotient 3 as the next digit in the result. 
Result so far: 10114.74712643
If we take 261 away from 320, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

The final outcome is 10114.74712643, with a leftover of 5.9e-08.
