Let's divide 870439 by 63
Our goal is to divide 870439 by 63.

Going ahead to step 1:
When dividing 8 by 63, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 63

Step 2:
63 can be fit into 87 1 times, resulting in a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 63 from 87, we get 24.
Bring next digit (0) of the dividend behind the 24 and repeat the process: 240 / 63

Going ahead to step 3:
240 divided by 63 is 3 with a remainder of 51.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we subtract 189 from 240, we get 51.
Fetch the next digit (4) from the dividend, attach it to 51 and continue: 514 / 63

Going ahead to step 4:
When dividing 514 by 63, we get 8 with a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 138.0
Deduct 504 from 514 and we're left with 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 63

Let's proceed to step 5:
63 goes into 103 1 times with a remainder of 40.
Use 1 as the next digit of our solution. 
Result so far: 1381.0
Subtracting 63 from 103 leaves us with 40.
Bring next digit (9) of the dividend behind the 40 and repeat the process: 409 / 63

Let's proceed to step 6:
63 can be fit into 409 6 times, resulting in a remainder of 31.
The number 6 becomes the next digit in our result. 
Result so far: 13816.0
The remainder is 31 after subtracting 378 from 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 7:
63 goes into 310 4 times with a remainder of 58.
Put 4 as the next digit of the answer. 
Result so far: 13816.4
If we take 252 away from 310, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 8:
When dividing 580 by 63, we get 9 with a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 13816.49
Deduct 567 from 580 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 9:
130 divided by 63 is 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 13816.492
If we take 126 away from 130, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
63 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 13816.492
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
If we divide 400 by 63, we get 6 and a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 13816.49206
Subtracting 378 from 400 leaves us 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.

On to step 12:
When dividing 220 by 63, we get 3 with a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 13816.492063
If we subtract 189 from 220, 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:
When dividing 310 by 63, we get 4 with a remainder of 58.
Write down 4 as next digit of the result. 
Result so far: 13816.4920634
Deduct 252 from 310 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 14:
If we divide 580 by 63, we get 9 and a remainder of 13.
The next digit of our result is 9. 
Result so far: 13816.49206349
Subtract 567 from 580 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

In conclusion, the division gives 13816.49206349 with a balance of 1.3e-08.
