Let's divide 939423 by 87
Our goal is to divide 939423 by 87.

On to step 1:
The number 87 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 87

Moving on to step 2:
The number 87 fits into 93 1 times, leaving a remainder of 6.
Use 1 as the next digit of our solution. 
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

Let's proceed to step 3:
69 divided by 87 is 0 with a remainder of 69.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 69, we end up with 69.
Fetch the next digit (4) from the dividend, attach it to 69 and continue: 694 / 87

Moving on to step 4:
87 goes into 694 7 times with a remainder of 85.
The number 7 becomes the next digit in our result. 
Result so far: 107.0
The remainder is 85 after subtracting 609 from 694.
Fetch the next digit (2) from the dividend, attach it to 85 and continue: 852 / 87

Let's proceed to step 5:
The number 87 fits into 852 9 times, leaving a remainder of 69.
Put 9 as the next digit of the answer. 
Result so far: 1079.0
Deduct 783 from 852 and we're left with 69.
Bring next digit (3) of the dividend behind the 69 and repeat the process: 693 / 87

Moving on to step 6:
693 divided by 87 is 7 with a remainder of 84.
Put 7 as the next digit of the answer. 
Result so far: 10797.0
If we take 609 away from 693, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 7:
When dividing 840 by 87, we get 9 with a remainder of 57.
Put 9 as the next digit of the answer. 
Result so far: 10797.9
If we take 783 away from 840, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 8:
The number 87 fits into 570 6 times, leaving a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 10797.96
Subtract 522 from 570 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 9:
When dividing 480 by 87, we get 5 with a remainder of 45.
The next digit of our result is 5. 
Result so far: 10797.965
If we take 435 away from 480, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 10:
The number 87 fits into 450 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 10797.9655
Deduct 435 from 450 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

In conclusion, the division gives 10797.9655 with a balance of 0.00015.
