We're dividing 77642392 by 630 
Our goal is to divide 77642392 by 630.

On to step 1:
When dividing 7 by 630, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 630

Advancing to step 2:
The number 630 fits into 77 0 times, leaving a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Append the next digit (6) from the dividend to 77 and continue with: 776 / 630

Moving on to step 3:
When dividing 776 by 630, we get 1 with a remainder of 146.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 630 from 776 to get 146.
Bring next digit (4) of the dividend behind the 146 and repeat the process: 1464 / 630

Advancing to step 4:
630 can be fit into 1464 2 times, resulting in a remainder of 204.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 1260 from 1464 to get 204.
Append the next digit (2) from the dividend to 204 and continue with: 2042 / 630

Let's proceed to step 5:
630 can be fit into 2042 3 times, resulting in a remainder of 152.
Record the quotient 3 as the next digit in the result. 
Result so far: 123.0
Subtract 1890 from 2042 to get 152.
Append the next digit (3) from the dividend to 152 and continue with: 1523 / 630

Advancing to step 6:
The number 630 fits into 1523 2 times, leaving a remainder of 263.
The next digit of our result is 2. 
Result so far: 1232.0
Subtracting 1260 from 1523 leaves us with 263.
Append the next digit (9) from the dividend to 263 and continue with: 2639 / 630

Moving on to step 7:
630 goes into 2639 4 times with a remainder of 119.
Put 4 as the next digit of the answer. 
Result so far: 12324.0
The remainder is 119 after subtracting 2520 from 2639.
Include the next digit (2) from the dividend after 119, then repeat: 1192 / 630

Advancing to step 8:
1192 divided by 630 is 1 with a remainder of 562.
The next digit of our result is 1. 
Result so far: 123241.0
The remainder is 562 after subtracting 630 from 1192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

On to step 9:
The number 630 fits into 5620 8 times, leaving a remainder of 580.
Record the quotient 8 as the next digit in the result. 
Result so far: 123241.8
If we subtract 5040 from 5620, we get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Moving on to step 10:
If we divide 5800 by 630, we get 9 and a remainder of 130.
Use 9 as the next digit of our solution. 
Result so far: 123241.89
Subtracting 5670 from 5800 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 11:
1300 divided by 630 is 2 with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 123241.892
The remainder is 40 after subtracting 1260 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
630 goes into 400 0 times with a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 123241.892
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 13:
If we divide 4000 by 630, we get 6 and a remainder of 220.
The number 6 becomes the next digit in our result. 
Result so far: 123241.89206
If we subtract 3780 from 4000, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 14:
When dividing 2200 by 630, we get 3 with a remainder of 310.
The next digit of our result is 3. 
Result so far: 123241.892063
Subtract 1890 from 2200 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Advancing to step 15:
The number 630 fits into 3100 4 times, leaving a remainder of 580.
Use 4 as the next digit of our solution. 
Result so far: 123241.8920634
Subtracting 2520 from 3100 leaves us with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Let's proceed to step 16:
The number 630 fits into 5800 9 times, leaving a remainder of 130.
Record the quotient 9 as the next digit in the result. 
Result so far: 123241.89206349
If we take 5670 away from 5800, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

The quotient of the division is 123241.89206349, and the remainder is 1.3e-07.
