212551 ÷ 48 
Let's see how many times 48 fits into 212551.

Step 1:
48 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 48

Advancing to step 2:
48 goes into 21 0 times with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 48

Advancing to step 3:
48 goes into 212 4 times with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 20 after subtracting 192 from 212.
Take the next digit (5) from the dividend and append it to 20, then repeat: 205 / 48

On to step 4:
If we divide 205 by 48, we get 4 and a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 44.0
If we subtract 192 from 205, we get 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 48

Going ahead to step 5:
The number 48 fits into 135 2 times, leaving a remainder of 39.
Put 2 as the next digit of the answer. 
Result so far: 442.0
If we subtract 96 from 135, we get 39.
Grab the next digit (1) from the dividend, add it to 39, then carry on: 391 / 48

Going ahead to step 6:
The number 48 fits into 391 8 times, leaving a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 4428.0
The remainder is 7 after subtracting 384 from 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
48 can be fit into 70 1 times, resulting in a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 4428.1
If we take 48 away from 70, we end up 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.

Advancing to step 8:
220 divided by 48 is 4 with a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 4428.14
If we take 192 away from 220, we end up 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.

Advancing to step 9:
If we divide 280 by 48, we get 5 and a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 4428.145
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:
If we divide 400 by 48, we get 8 and a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 4428.1458
If we take 384 away from 400, we end up 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.

Let's proceed to step 11:
When dividing 160 by 48, we get 3 with a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 4428.14583
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.

On to step 12:
If we divide 160 by 48, we get 3 and a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 4428.145833
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 4428.145833 and a remainder of 1.6e-06.
