We're dividing 80374845 by 630 
We want to figure out the number of times 80374845 can be divided by 630.

Step 1:
8 divided by 630 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 630

Let's proceed to step 2:
630 can be fit into 80 0 times, resulting in a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Append the next digit (3) from the dividend to 80 and continue with: 803 / 630

Step 3:
630 can be fit into 803 1 times, resulting in a remainder of 173.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 630 from 803 to get 173.
Grab the next digit (7) from the dividend, add it to 173, then carry on: 1737 / 630

Going ahead to step 4:
The number 630 fits into 1737 2 times, leaving a remainder of 477.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 1260 from 1737, we get 477.
Fetch the next digit (4) from the dividend, attach it to 477 and continue: 4774 / 630

Going ahead to step 5:
4774 divided by 630 is 7 with a remainder of 364.
Put 7 as the next digit of the answer. 
Result so far: 127.0
The remainder is 364 after subtracting 4410 from 4774.
Include the next digit (8) from the dividend after 364, then repeat: 3648 / 630

Let's proceed to step 6:
630 goes into 3648 5 times with a remainder of 498.
Put 5 as the next digit of the answer. 
Result so far: 1275.0
Subtracting 3150 from 3648 leaves us with 498.
Grab the next digit (4) from the dividend, add it to 498, then carry on: 4984 / 630

Advancing to step 7:
If we divide 4984 by 630, we get 7 and a remainder of 574.
Put 7 as the next digit of the answer. 
Result so far: 12757.0
Subtract 4410 from 4984 to get 574.
Include the next digit (5) from the dividend after 574, then repeat: 5745 / 630

Let's proceed to step 8:
630 goes into 5745 9 times with a remainder of 75.
The next digit of our result is 9. 
Result so far: 127579.0
Deduct 5670 from 5745 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 9:
630 goes into 750 1 times with a remainder of 120.
Use 1 as the next digit of our solution. 
Result so far: 127579.1
Subtract 630 from 750 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 10:
630 can be fit into 1200 1 times, resulting in a remainder of 570.
The number 1 becomes the next digit in our result. 
Result so far: 127579.11
The remainder is 570 after subtracting 630 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

The final result is 127579.11 with a remainder of 0.57.
