We divide 815979 by 48
We're looking to find how many times 48 goes into 815979.

Step 1:
The number 48 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 48

On to step 2:
81 divided by 48 is 1 with a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 48 from 81 and we're left with 33.
Append the next digit (5) from the dividend to 33 and continue with: 335 / 48

Moving on to step 3:
48 goes into 335 6 times with a remainder of 47.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtract 288 from 335 to get 47.
Bring next digit (9) of the dividend behind the 47 and repeat the process: 479 / 48

Advancing to step 4:
If we divide 479 by 48, we get 9 and a remainder of 47.
Use 9 as the next digit of our solution. 
Result so far: 169.0
Subtracting 432 from 479 leaves us with 47.
Grab the next digit (7) from the dividend, add it to 47, then carry on: 477 / 48

Moving on to step 5:
48 can be fit into 477 9 times, resulting in a remainder of 45.
The number 9 becomes the next digit in our result. 
Result so far: 1699.0
If we take 432 away from 477, we end up with 45.
Fetch the next digit (9) from the dividend, attach it to 45 and continue: 459 / 48

Moving on to step 6:
459 divided by 48 is 9 with a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 16999.0
The remainder is 27 after subtracting 432 from 459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 7:
When dividing 270 by 48, we get 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 16999.5
If we subtract 240 from 270, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
48 can be fit into 300 6 times, resulting in a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 16999.56
Deduct 288 from 300 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
48 can be fit into 120 2 times, resulting in a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 16999.562
If we subtract 96 from 120, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 10:
48 can be fit into 240 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 16999.5625
The remainder is 0 after subtracting 240 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
The number 48 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 16999.5625
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 12:
The number 48 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 16999.5625
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 16999.5625, with a leftover of 0.0.
