We look at the division of 45871370 by 630 
We want to divide 45871370 by 630.

Advancing to step 1:
The number 630 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 630

Advancing to step 2:
45 divided by 630 is 0 with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Fetch the next digit (8) from the dividend, attach it to 45 and continue: 458 / 630

Going ahead to step 3:
630 goes into 458 0 times with a remainder of 458.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 458, we end up with 458.
Append the next digit (7) from the dividend to 458 and continue with: 4587 / 630

Moving on to step 4:
630 can be fit into 4587 7 times, resulting in a remainder of 177.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 4410 from 4587, we get 177.
Bring next digit (1) of the dividend behind the 177 and repeat the process: 1771 / 630

Advancing to step 5:
The number 630 fits into 1771 2 times, leaving a remainder of 511.
The number 2 becomes the next digit in our result. 
Result so far: 72.0
If we subtract 1260 from 1771, we get 511.
Take the next digit (3) from the dividend and append it to 511, then repeat: 5113 / 630

Advancing to step 6:
5113 divided by 630 is 8 with a remainder of 73.
The number 8 becomes the next digit in our result. 
Result so far: 728.0
If we subtract 5040 from 5113, we get 73.
Fetch the next digit (7) from the dividend, attach it to 73 and continue: 737 / 630

Step 7:
630 can be fit into 737 1 times, resulting in a remainder of 107.
Use 1 as the next digit of our solution. 
Result so far: 7281.0
Deduct 630 from 737 and we're left with 107.
Take the next digit (0) from the dividend and append it to 107, then repeat: 1070 / 630

On to step 8:
When dividing 1070 by 630, we get 1 with a remainder of 440.
The number 1 becomes the next digit in our result. 
Result so far: 72811.0
The remainder is 440 after subtracting 630 from 1070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 9:
4400 divided by 630 is 6 with a remainder of 620.
Write down 6 as next digit of the result. 
Result so far: 72811.6
If we subtract 3780 from 4400, we get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

On to step 10:
The number 630 fits into 6200 9 times, leaving a remainder of 530.
The next digit of our result is 9. 
Result so far: 72811.69
If we subtract 5670 from 6200, we get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Going ahead to step 11:
630 goes into 5300 8 times with a remainder of 260.
The next digit of our result is 8. 
Result so far: 72811.698
If we subtract 5040 from 5300, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 12:
The number 630 fits into 2600 4 times, leaving a remainder of 80.
Use 4 as the next digit of our solution. 
Result so far: 72811.6984
Deduct 2520 from 2600 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 13:
800 divided by 630 is 1 with a remainder of 170.
Put 1 as the next digit of the answer. 
Result so far: 72811.69841
Subtracting 630 from 800 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 14:
1700 divided by 630 is 2 with a remainder of 440.
Record the quotient 2 as the next digit in the result. 
Result so far: 72811.698412
Deduct 1260 from 1700 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 15:
When dividing 4400 by 630, we get 6 with a remainder of 620.
The number 6 becomes the next digit in our result. 
Result so far: 72811.6984126
Deduct 3780 from 4400 and we're left with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Let's proceed to step 16:
630 goes into 6200 9 times with a remainder of 530.
Use 9 as the next digit of our solution. 
Result so far: 72811.69841269
If we subtract 5670 from 6200, we get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

The final outcome is 72811.69841269, with a leftover of 5.3e-07.
