421778 ÷ 48 
Let's see how many times 48 fits into 421778.

Moving on to step 1:
48 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 48

Moving on to step 2:
The number 48 fits into 42 0 times, leaving a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Append the next digit (1) from the dividend to 42 and continue with: 421 / 48

Going ahead to step 3:
The number 48 fits into 421 8 times, leaving a remainder of 37.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 384 from 421 and we're left with 37.
Grab the next digit (7) from the dividend, add it to 37, then carry on: 377 / 48

On to step 4:
48 can be fit into 377 7 times, resulting in a remainder of 41.
Use 7 as the next digit of our solution. 
Result so far: 87.0
Subtracting 336 from 377 leaves us with 41.
Bring next digit (7) of the dividend behind the 41 and repeat the process: 417 / 48

Advancing to step 5:
48 goes into 417 8 times with a remainder of 33.
Write down 8 as next digit of the result. 
Result so far: 878.0
If we take 384 away from 417, we end up with 33.
Append the next digit (8) from the dividend to 33 and continue with: 338 / 48

Step 6:
If we divide 338 by 48, we get 7 and a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 8787.0
Subtract 336 from 338 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
48 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 8787.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
48 goes into 200 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 8787.04
Subtracting 192 from 200 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
If we divide 80 by 48, we get 1 and a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 8787.041
The remainder is 32 after subtracting 48 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 10:
48 goes into 320 6 times with a remainder of 32.
The next digit of our result is 6. 
Result so far: 8787.0416
If we subtract 288 from 320, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 11:
When dividing 320 by 48, we get 6 with a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 8787.04166
Subtract 288 from 320 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 8787.04166, and the remainder is 3.2e-05.
