We're dividing 81018061 by 630 
Let's see how many times 630 fits into 81018061.

Let's proceed to step 1:
The number 630 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 630

Going ahead to step 2:
630 can be fit into 81 0 times, resulting in a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Fetch the next digit (0) from the dividend, attach it to 81 and continue: 810 / 630

Step 3:
810 divided by 630 is 1 with a remainder of 180.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 630 away from 810, we end up with 180.
Fetch the next digit (1) from the dividend, attach it to 180 and continue: 1801 / 630

Let's proceed to step 4:
1801 divided by 630 is 2 with a remainder of 541.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 1260 from 1801 to get 541.
Include the next digit (8) from the dividend after 541, then repeat: 5418 / 630

Going ahead to step 5:
When dividing 5418 by 630, we get 8 with a remainder of 378.
Record the quotient 8 as the next digit in the result. 
Result so far: 128.0
The remainder is 378 after subtracting 5040 from 5418.
Grab the next digit (0) from the dividend, add it to 378, then carry on: 3780 / 630

Going ahead to step 6:
630 can be fit into 3780 6 times, resulting in a remainder of 0.
The next digit of our result is 6. 
Result so far: 1286.0
If we take 3780 away from 3780, we end up with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 630

Going ahead to step 7:
630 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 12860.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 630

Let's proceed to step 8:
When dividing 61 by 630, we get 0 with a remainder of 61.
The number 0 becomes the next digit in our result. 
Result so far: 128600.0
If we take 0 away from 61, 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.

Advancing to step 9:
630 can be fit into 610 0 times, resulting in a remainder of 610.
Put 0 as the next digit of the answer. 
Result so far: 128600.0
The remainder is 610 after subtracting 0 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Going ahead to step 10:
6100 divided by 630 is 9 with a remainder of 430.
Use 9 as the next digit of our solution. 
Result so far: 128600.09
If we take 5670 away from 6100, we end up with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

On to step 11:
630 can be fit into 4300 6 times, resulting in a remainder of 520.
Use 6 as the next digit of our solution. 
Result so far: 128600.096
Deduct 3780 from 4300 and we're left with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 12:
630 can be fit into 5200 8 times, resulting in a remainder of 160.
Write down 8 as next digit of the result. 
Result so far: 128600.0968
If we take 5040 away from 5200, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 13:
1600 divided by 630 is 2 with a remainder of 340.
The number 2 becomes the next digit in our result. 
Result so far: 128600.09682
Deduct 1260 from 1600 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 14:
When dividing 3400 by 630, we get 5 with a remainder of 250.
The next digit of our result is 5. 
Result so far: 128600.096825
Subtracting 3150 from 3400 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 15:
When dividing 2500 by 630, we get 3 with a remainder of 610.
Write down 3 as next digit of the result. 
Result so far: 128600.0968253
If we subtract 1890 from 2500, we get 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Advancing to step 16:
6100 divided by 630 is 9 with a remainder of 430.
The number 9 becomes the next digit in our result. 
Result so far: 128600.09682539
Subtracting 5670 from 6100 leaves us with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

The final outcome is 128600.09682539, with a leftover of 4.3e-07.
