We're dividing 213146 by 51 
Our goal is to divide 213146 by 51.

Going ahead to step 1:
When dividing 2 by 51, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the 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

Going ahead to step 2:
The number 51 fits into 21 0 times, leaving a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Fetch the next digit (3) from the dividend, attach it to 21 and continue: 213 / 51

Going ahead to step 3:
213 divided by 51 is 4 with a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 204 from 213 leaves us with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 51

Step 4:
91 divided by 51 is 1 with a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
Subtract 51 from 91 to get 40.
Append the next digit (4) from the dividend to 40 and continue with: 404 / 51

Moving on to step 5:
51 can be fit into 404 7 times, resulting in a remainder of 47.
Write down 7 as next digit of the result. 
Result so far: 417.0
Subtracting 357 from 404 leaves us with 47.
Fetch the next digit (6) from the dividend, attach it to 47 and continue: 476 / 51

Going ahead to step 6:
When dividing 476 by 51, we get 9 with a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 4179.0
Subtracting 459 from 476 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 7:
The number 51 fits into 170 3 times, leaving a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 4179.3
If we subtract 153 from 170, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 8:
The number 51 fits into 170 3 times, leaving a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 4179.33
If we subtract 153 from 170, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final outcome is 4179.33, with a leftover of 0.017.
