631615 divided by 48 
We want to figure out the number of times 631615 can be divided by 48.

On to step 1:
The number 48 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 48

Step 2:
48 can be fit into 63 1 times, resulting in a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 48 from 63 and we're left with 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 48

Step 3:
48 goes into 151 3 times with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 13.0
The remainder is 7 after subtracting 144 from 151.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 48

Advancing to step 4:
48 goes into 76 1 times with a remainder of 28.
The next digit of our result is 1. 
Result so far: 131.0
If we subtract 48 from 76, we get 28.
Fetch the next digit (1) from the dividend, attach it to 28 and continue: 281 / 48

On to step 5:
If we divide 281 by 48, we get 5 and a remainder of 41.
Write down 5 as next digit of the result. 
Result so far: 1315.0
The remainder is 41 after subtracting 240 from 281.
Bring next digit (5) of the dividend behind the 41 and repeat the process: 415 / 48

Going ahead to step 6:
48 goes into 415 8 times with a remainder of 31.
Record the quotient 8 as the next digit in the result. 
Result so far: 13158.0
Deduct 384 from 415 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 7:
48 goes into 310 6 times with a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 13158.6
Subtracting 288 from 310 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 8:
If we divide 220 by 48, we get 4 and a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 13158.64
Subtracting 192 from 220 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 9:
280 divided by 48 is 5 with a remainder of 40.
The next digit of our result is 5. 
Result so far: 13158.645
The remainder is 40 after subtracting 240 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
48 goes into 400 8 times with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 13158.6458
Subtracting 384 from 400 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
If we divide 160 by 48, we get 3 and a remainder of 16.
The next digit of our result is 3. 
Result so far: 13158.64583
If we subtract 144 from 160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 12:
160 divided by 48 is 3 with a remainder of 16.
The next digit of our result is 3. 
Result so far: 13158.645833
Deduct 144 from 160 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 13158.645833, with a leftover of 1.6e-06.
