64508404 ÷ 630 
We want to figure out the number of times 64508404 can be divided by 630.

Let's proceed to step 1:
630 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 630

Step 2:
When dividing 64 by 630, we get 0 with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Fetch the next digit (5) from the dividend, attach it to 64 and continue: 645 / 630

Advancing to step 3:
If we divide 645 by 630, we get 1 and a remainder of 15.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 630 from 645 to get 15.
Include the next digit (0) from the dividend after 15, then repeat: 150 / 630

Going ahead to step 4:
The number 630 fits into 150 0 times, leaving a remainder of 150.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 150 after subtracting 0 from 150.
Bring next digit (8) of the dividend behind the 150 and repeat the process: 1508 / 630

Step 5:
630 can be fit into 1508 2 times, resulting in a remainder of 248.
Use 2 as the next digit of our solution. 
Result so far: 102.0
If we take 1260 away from 1508, we end up with 248.
Fetch the next digit (4) from the dividend, attach it to 248 and continue: 2484 / 630

Let's proceed to step 6:
630 goes into 2484 3 times with a remainder of 594.
Use 3 as the next digit of our solution. 
Result so far: 1023.0
Subtract 1890 from 2484 to get 594.
Take the next digit (0) from the dividend and append it to 594, then repeat: 5940 / 630

Advancing to step 7:
630 can be fit into 5940 9 times, resulting in a remainder of 270.
Put 9 as the next digit of the answer. 
Result so far: 10239.0
The remainder is 270 after subtracting 5670 from 5940.
Include the next digit (4) from the dividend after 270, then repeat: 2704 / 630

Step 8:
The number 630 fits into 2704 4 times, leaving a remainder of 184.
Write down 4 as next digit of the result. 
Result so far: 102394.0
If we take 2520 away from 2704, we end up with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 9:
The number 630 fits into 1840 2 times, leaving a remainder of 580.
Write down 2 as next digit of the result. 
Result so far: 102394.2
Subtract 1260 from 1840 to 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.

On to step 10:
5800 divided by 630 is 9 with a remainder of 130.
The next digit of our result is 9. 
Result so far: 102394.29
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.

Advancing to step 11:
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: 102394.292
Deduct 1260 from 1300 and we're left 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 12:
If we divide 400 by 630, we get 0 and a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 102394.292
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.

Let's proceed to step 13:
630 can be fit into 4000 6 times, resulting in a remainder of 220.
Put 6 as the next digit of the answer. 
Result so far: 102394.29206
The remainder is 220 after subtracting 3780 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 14:
630 can be fit into 2200 3 times, resulting in a remainder of 310.
Put 3 as the next digit of the answer. 
Result so far: 102394.292063
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.

Moving on to step 15:
If we divide 3100 by 630, we get 4 and a remainder of 580.
Put 4 as the next digit of the answer. 
Result so far: 102394.2920634
If we take 2520 away from 3100, we end up 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.
Put 9 as the next digit of the answer. 
Result so far: 102394.29206349
If we subtract 5670 from 5800, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Our division results in 102394.29206349 with a remaining 1.3e-07.
