840979 divided by 87 
Let's see how many times 87 fits into 840979.

On to step 1:
The number 87 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 87

Let's proceed to step 2:
84 divided by 87 is 0 with a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 84 to get 84.
Grab the next digit (0) from the dividend, add it to 84, then carry on: 840 / 87

Let's proceed to step 3:
If we divide 840 by 87, we get 9 and a remainder of 57.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 783 from 840, we get 57.
Fetch the next digit (9) from the dividend, attach it to 57 and continue: 579 / 87

Let's proceed to step 4:
87 can be fit into 579 6 times, resulting in a remainder of 57.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
Subtracting 522 from 579 leaves us with 57.
Append the next digit (7) from the dividend to 57 and continue with: 577 / 87

On to step 5:
If we divide 577 by 87, we get 6 and a remainder of 55.
Write down 6 as next digit of the result. 
Result so far: 966.0
The remainder is 55 after subtracting 522 from 577.
Bring next digit (9) of the dividend behind the 55 and repeat the process: 559 / 87

Step 6:
The number 87 fits into 559 6 times, leaving a remainder of 37.
Put 6 as the next digit of the answer. 
Result so far: 9666.0
The remainder is 37 after subtracting 522 from 559.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 7:
When dividing 370 by 87, we get 4 with a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 9666.4
If we subtract 348 from 370, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 8:
87 goes into 220 2 times with a remainder of 46.
Record the quotient 2 as the next digit in the result. 
Result so far: 9666.42
If we subtract 174 from 220, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 9:
87 can be fit into 460 5 times, resulting in a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 9666.425
If we take 435 away from 460, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 10:
If we divide 250 by 87, we get 2 and a remainder of 76.
The number 2 becomes the next digit in our result. 
Result so far: 9666.4252
Subtracting 174 from 250 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 11:
If we divide 760 by 87, we get 8 and a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 9666.42528
The remainder is 64 after subtracting 696 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 12:
640 divided by 87 is 7 with a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 9666.425287
If we subtract 609 from 640, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 13:
310 divided by 87 is 3 with a remainder of 49.
The next digit of our result is 3. 
Result so far: 9666.4252873
Deduct 261 from 310 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 14:
If we divide 490 by 87, we get 5 and a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 9666.42528735
If we take 435 away from 490, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Our division results in 9666.42528735 with a remaining 5.5e-08.
