Let's divide 7578789 by 63
Our goal is to divide 7578789 by 63.

Going ahead to step 1:
If we divide 7 by 63, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 63

Let's proceed to step 2:
75 divided by 63 is 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 63 from 75 leaves us with 12.
Fetch the next digit (7) from the dividend, attach it to 12 and continue: 127 / 63

Step 3:
When dividing 127 by 63, we get 2 with a remainder of 1.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 126 from 127, we get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 63

Let's proceed to step 4:
If we divide 18 by 63, we get 0 and a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 120.0
Deduct 0 from 18 and we're left with 18.
Fetch the next digit (7) from the dividend, attach it to 18 and continue: 187 / 63

Moving on to step 5:
63 goes into 187 2 times with a remainder of 61.
The next digit of our result is 2. 
Result so far: 1202.0
The remainder is 61 after subtracting 126 from 187.
Fetch the next digit (8) from the dividend, attach it to 61 and continue: 618 / 63

Step 6:
The number 63 fits into 618 9 times, leaving a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 12029.0
If we take 567 away from 618, we end up with 51.
Bring next digit (9) of the dividend behind the 51 and repeat the process: 519 / 63

On to step 7:
63 goes into 519 8 times with a remainder of 15.
Write down 8 as next digit of the result. 
Result so far: 120298.0
Subtract 504 from 519 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 8:
63 can be fit into 150 2 times, resulting in a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 120298.2
The remainder is 24 after subtracting 126 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 9:
The number 63 fits into 240 3 times, leaving a remainder of 51.
The number 3 becomes the next digit in our result. 
Result so far: 120298.23
The remainder is 51 after subtracting 189 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 10:
The number 63 fits into 510 8 times, leaving a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 120298.238
Subtract 504 from 510 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 11:
The number 63 fits into 60 0 times, leaving a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 120298.238
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 12:
When dividing 600 by 63, we get 9 with a remainder of 33.
Use 9 as the next digit of our solution. 
Result so far: 120298.23809
Deduct 567 from 600 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 13:
63 can be fit into 330 5 times, resulting in a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 120298.238095
Subtract 315 from 330 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 14:
When dividing 150 by 63, we get 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 120298.2380952
The remainder is 24 after subtracting 126 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 15:
240 divided by 63 is 3 with a remainder of 51.
Write down 3 as next digit of the result. 
Result so far: 120298.23809523
Subtracting 189 from 240 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The final outcome is 120298.23809523, with a leftover of 5.1e-08.
