We look at the division of 939421 by 87 
We want to divide 939421 by 87.

Let's proceed to step 1:
The number 87 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 87

Step 2:
When dividing 93 by 87, we get 1 with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 87 from 93 to get 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 87

On to step 3:
The number 87 fits into 69 0 times, leaving a remainder of 69.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 69 and we're left with 69.
Append the next digit (4) from the dividend to 69 and continue with: 694 / 87

Let's proceed to step 4:
When dividing 694 by 87, we get 7 with a remainder of 85.
Use 7 as the next digit of our solution. 
Result so far: 107.0
If we take 609 away from 694, we end up with 85.
Bring next digit (2) of the dividend behind the 85 and repeat the process: 852 / 87

Moving on to step 5:
If we divide 852 by 87, we get 9 and a remainder of 69.
Record the quotient 9 as the next digit in the result. 
Result so far: 1079.0
The remainder is 69 after subtracting 783 from 852.
Bring next digit (1) of the dividend behind the 69 and repeat the process: 691 / 87

Let's proceed to step 6:
87 goes into 691 7 times with a remainder of 82.
Put 7 as the next digit of the answer. 
Result so far: 10797.0
Deduct 609 from 691 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 7:
If we divide 820 by 87, we get 9 and a remainder of 37.
Write down 9 as next digit of the result. 
Result so far: 10797.9
Deduct 783 from 820 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 8:
If we divide 370 by 87, we get 4 and a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 10797.94
Deduct 348 from 370 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 9:
If we divide 220 by 87, we get 2 and a remainder of 46.
Record the quotient 2 as the next digit in the result. 
Result so far: 10797.942
Deduct 174 from 220 and we're left with 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 10:
When dividing 460 by 87, we get 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 10797.9425
Deduct 435 from 460 and we're left 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.

Let's proceed to step 11:
250 divided by 87 is 2 with a remainder of 76.
Put 2 as the next digit of the answer. 
Result so far: 10797.94252
Subtract 174 from 250 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 12:
760 divided by 87 is 8 with a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 10797.942528
If we subtract 696 from 760, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 13:
640 divided by 87 is 7 with a remainder of 31.
Record the quotient 7 as the next digit in the result. 
Result so far: 10797.9425287
Deduct 609 from 640 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 14:
If we divide 310 by 87, we get 3 and a remainder of 49.
Record the quotient 3 as the next digit in the result. 
Result so far: 10797.94252873
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.

Our division results in 10797.94252873 with a remaining 4.9e-08.
