We look at the division of 766870 by 63 
Let's see how many times 63 fits into 766870.

Moving on to step 1:
When dividing 7 by 63, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 63

Moving on to step 2:
76 divided by 63 is 1 with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 63 from 76, we get 13.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 63

Moving on to step 3:
If we divide 136 by 63, we get 2 and a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 126 away from 136, we end up with 10.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 63

Going ahead to step 4:
108 divided by 63 is 1 with a remainder of 45.
Record the quotient 1 as the next digit in the result. 
Result so far: 121.0
Subtracting 63 from 108 leaves us with 45.
Take the next digit (7) from the dividend and append it to 45, then repeat: 457 / 63

Let's proceed to step 5:
If we divide 457 by 63, we get 7 and a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 1217.0
If we take 441 away from 457, we end up with 16.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 63

Going ahead to step 6:
The number 63 fits into 160 2 times, leaving a remainder of 34.
Put 2 as the next digit of the answer. 
Result so far: 12172.0
If we take 126 away from 160, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 7:
63 can be fit into 340 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 12172.5
The remainder is 25 after subtracting 315 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 8:
250 divided by 63 is 3 with a remainder of 61.
The next digit of our result is 3. 
Result so far: 12172.53
If we take 189 away from 250, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 9:
610 divided by 63 is 9 with a remainder of 43.
Put 9 as the next digit of the answer. 
Result so far: 12172.539
Deduct 567 from 610 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 10:
63 can be fit into 430 6 times, resulting in a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 12172.5396
If we subtract 378 from 430, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 11:
63 goes into 520 8 times with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 12172.53968
Deduct 504 from 520 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 12:
63 can be fit into 160 2 times, resulting in a remainder of 34.
Put 2 as the next digit of the answer. 
Result so far: 12172.539682
The remainder is 34 after subtracting 126 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 13:
340 divided by 63 is 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 12172.5396825
The remainder is 25 after subtracting 315 from 340.
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 14:
The number 63 fits into 250 3 times, leaving a remainder of 61.
The next digit of our result is 3. 
Result so far: 12172.53968253
Subtract 189 from 250 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

The final outcome is 12172.53968253, with a leftover of 6.1e-08.
