Let's divide 54586447 by 630
We want to figure out the number of times 54586447 can be divided by 630.

On to step 1:
If we divide 5 by 630, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 630

Step 2:
630 goes into 54 0 times with a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Bring next digit (5) of the dividend behind the 54 and repeat the process: 545 / 630

Going ahead to step 3:
When dividing 545 by 630, we get 0 with a remainder of 545.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 545 leaves us with 545.
Append the next digit (8) from the dividend to 545 and continue with: 5458 / 630

On to step 4:
630 can be fit into 5458 8 times, resulting in a remainder of 418.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 418 after subtracting 5040 from 5458.
Append the next digit (6) from the dividend to 418 and continue with: 4186 / 630

On to step 5:
When dividing 4186 by 630, we get 6 with a remainder of 406.
The next digit of our result is 6. 
Result so far: 86.0
Subtracting 3780 from 4186 leaves us with 406.
Grab the next digit (4) from the dividend, add it to 406, then carry on: 4064 / 630

Step 6:
4064 divided by 630 is 6 with a remainder of 284.
The next digit of our result is 6. 
Result so far: 866.0
Deduct 3780 from 4064 and we're left with 284.
Take the next digit (4) from the dividend and append it to 284, then repeat: 2844 / 630

Advancing to step 7:
630 goes into 2844 4 times with a remainder of 324.
The next digit of our result is 4. 
Result so far: 8664.0
If we take 2520 away from 2844, we end up with 324.
Append the next digit (7) from the dividend to 324 and continue with: 3247 / 630

Step 8:
630 goes into 3247 5 times with a remainder of 97.
Put 5 as the next digit of the answer. 
Result so far: 86645.0
If we take 3150 away from 3247, we end up with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Going ahead to step 9:
630 can be fit into 970 1 times, resulting in a remainder of 340.
The number 1 becomes the next digit in our result. 
Result so far: 86645.1
If we take 630 away from 970, we end up 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.

On to step 10:
If we divide 3400 by 630, we get 5 and a remainder of 250.
Record the quotient 5 as the next digit in the result. 
Result so far: 86645.15
Subtract 3150 from 3400 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 11:
When dividing 2500 by 630, we get 3 with a remainder of 610.
The next digit of our result is 3. 
Result so far: 86645.153
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.

On to step 12:
630 goes into 6100 9 times with a remainder of 430.
Record the quotient 9 as the next digit in the result. 
Result so far: 86645.1539
The remainder is 430 after subtracting 5670 from 6100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Advancing to step 13:
4300 divided by 630 is 6 with a remainder of 520.
Write down 6 as next digit of the result. 
Result so far: 86645.15396
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.

Advancing to step 14:
630 can be fit into 5200 8 times, resulting in a remainder of 160.
Use 8 as the next digit of our solution. 
Result so far: 86645.153968
Deduct 5040 from 5200 and we're left 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.

Advancing to step 15:
1600 divided by 630 is 2 with a remainder of 340.
The next digit of our result is 2. 
Result so far: 86645.1539682
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 16:
3400 divided by 630 is 5 with a remainder of 250.
The number 5 becomes the next digit in our result. 
Result so far: 86645.15396825
Deduct 3150 from 3400 and we're left 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.

The final outcome is 86645.15396825, with a leftover of 2.5e-07.
