We look at the division of 869786 by 63 
We're looking to find how many times 63 goes into 869786.

Let's proceed to step 1:
63 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 63

Going ahead to step 2:
63 can be fit into 86 1 times, resulting in a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 63 away from 86, we end up with 23.
Take the next digit (9) from the dividend and append it to 23, then repeat: 239 / 63

Going ahead to step 3:
63 can be fit into 239 3 times, resulting in a remainder of 50.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 189 from 239 and we're left with 50.
Grab the next digit (7) from the dividend, add it to 50, then carry on: 507 / 63

Going ahead to step 4:
If we divide 507 by 63, we get 8 and a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 138.0
Deduct 504 from 507 and we're left with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 63

Going ahead to step 5:
The number 63 fits into 38 0 times, leaving a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 1380.0
If we subtract 0 from 38, we get 38.
Bring next digit (6) of the dividend behind the 38 and repeat the process: 386 / 63

Advancing to step 6:
When dividing 386 by 63, we get 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 13806.0
If we subtract 378 from 386, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
63 goes into 80 1 times with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 13806.1
If we take 63 away from 80, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 8:
The number 63 fits into 170 2 times, leaving a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 13806.12
Deduct 126 from 170 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 9:
63 can be fit into 440 6 times, resulting in a remainder of 62.
The next digit of our result is 6. 
Result so far: 13806.126
Deduct 378 from 440 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.

Step 10:
The number 63 fits into 620 9 times, leaving a remainder of 53.
Put 9 as the next digit of the answer. 
Result so far: 13806.1269
The remainder is 53 after subtracting 567 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 11:
When dividing 530 by 63, we get 8 with a remainder of 26.
Put 8 as the next digit of the answer. 
Result so far: 13806.12698
The remainder is 26 after subtracting 504 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 12:
260 divided by 63 is 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 13806.126984
If we subtract 252 from 260, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
63 can be fit into 80 1 times, resulting in a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 13806.1269841
The remainder is 17 after subtracting 63 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 14:
63 goes into 170 2 times with a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 13806.12698412
If we subtract 126 from 170, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

After the division, we end up with 13806.12698412 and a remainder of 4.4e-08.
