80121613 divided by 630 
We want to divide 80121613 by 630.

Step 1:
630 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 630

Let's proceed to step 2:
When dividing 80 by 630, we get 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Take the next digit (1) from the dividend and append it to 80, then repeat: 801 / 630

Advancing to step 3:
801 divided by 630 is 1 with a remainder of 171.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 630 from 801 and we're left with 171.
Include the next digit (2) from the dividend after 171, then repeat: 1712 / 630

Let's proceed to step 4:
630 can be fit into 1712 2 times, resulting in a remainder of 452.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 1260 from 1712, we get 452.
Append the next digit (1) from the dividend to 452 and continue with: 4521 / 630

Let's proceed to step 5:
The number 630 fits into 4521 7 times, leaving a remainder of 111.
Use 7 as the next digit of our solution. 
Result so far: 127.0
Subtract 4410 from 4521 to get 111.
Include the next digit (6) from the dividend after 111, then repeat: 1116 / 630

Moving on to step 6:
630 goes into 1116 1 times with a remainder of 486.
Use 1 as the next digit of our solution. 
Result so far: 1271.0
Deduct 630 from 1116 and we're left with 486.
Fetch the next digit (1) from the dividend, attach it to 486 and continue: 4861 / 630

Moving on to step 7:
If we divide 4861 by 630, we get 7 and a remainder of 451.
Put 7 as the next digit of the answer. 
Result so far: 12717.0
Deduct 4410 from 4861 and we're left with 451.
Take the next digit (3) from the dividend and append it to 451, then repeat: 4513 / 630

On to step 8:
If we divide 4513 by 630, we get 7 and a remainder of 103.
The next digit of our result is 7. 
Result so far: 127177.0
If we take 4410 away from 4513, we end up with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Let's proceed to step 9:
630 can be fit into 1030 1 times, resulting in a remainder of 400.
The number 1 becomes the next digit in our result. 
Result so far: 127177.1
If we take 630 away from 1030, we end up with 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 10:
If we divide 4000 by 630, we get 6 and a remainder of 220.
Put 6 as the next digit of the answer. 
Result so far: 127177.16
If we take 3780 away from 4000, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 11:
The number 630 fits into 2200 3 times, leaving a remainder of 310.
The number 3 becomes the next digit in our result. 
Result so far: 127177.163
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 12:
When dividing 3100 by 630, we get 4 with a remainder of 580.
Write down 4 as next digit of the result. 
Result so far: 127177.1634
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.

On to step 13:
630 can be fit into 5800 9 times, resulting in a remainder of 130.
Use 9 as the next digit of our solution. 
Result so far: 127177.16349
The remainder is 130 after subtracting 5670 from 5800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 14:
The number 630 fits into 1300 2 times, leaving a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 127177.163492
If we take 1260 away from 1300, we end up 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.

Step 15:
400 divided by 630 is 0 with a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 127177.163492
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 16:
When dividing 4000 by 630, we get 6 with a remainder of 220.
Write down 6 as next digit of the result. 
Result so far: 127177.16349206
Subtract 3780 from 4000 to 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.

In conclusion, the division gives 127177.16349206 with a balance of 2.2e-07.
