Let's divide 212793 by 51
Let's see how many times 51 fits into 212793.

Let's proceed to step 1:
51 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 51

Advancing to step 2:
51 can be fit into 21 0 times, resulting in a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Fetch the next digit (2) from the dividend, attach it to 21 and continue: 212 / 51

Moving on to step 3:
51 goes into 212 4 times with a remainder of 8.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 204 from 212, we get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 51

Moving on to step 4:
51 can be fit into 87 1 times, resulting in a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 41.0
If we subtract 51 from 87, we get 36.
Fetch the next digit (9) from the dividend, attach it to 36 and continue: 369 / 51

On to step 5:
51 can be fit into 369 7 times, resulting in a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 417.0
The remainder is 12 after subtracting 357 from 369.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 51

On to step 6:
123 divided by 51 is 2 with a remainder of 21.
Use 2 as the next digit of our solution. 
Result so far: 4172.0
The remainder is 21 after subtracting 102 from 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 7:
210 divided by 51 is 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 4172.4
If we take 204 away from 210, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
51 can be fit into 60 1 times, resulting in a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 4172.41
If we take 51 away from 60, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 9:
If we divide 90 by 51, we get 1 and a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 4172.411
Subtract 51 from 90 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Our division results in 4172.411 with a remaining 0.0039.
