We look at the division of 622173 by 51 
We're looking to find how many times 51 goes into 622173.

Going ahead to step 1:
51 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 51

Let's proceed to step 2:
62 divided by 51 is 1 with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 51 from 62, we get 11.
Take the next digit (2) from the dividend and append it to 11, then repeat: 112 / 51

Advancing to step 3:
112 divided by 51 is 2 with a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 102 from 112, we get 10.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 51

On to step 4:
51 can be fit into 101 1 times, resulting in a remainder of 50.
The next digit of our result is 1. 
Result so far: 121.0
Subtract 51 from 101 to get 50.
Grab the next digit (7) from the dividend, add it to 50, then carry on: 507 / 51

On to step 5:
When dividing 507 by 51, we get 9 with a remainder of 48.
Write down 9 as next digit of the result. 
Result so far: 1219.0
Subtract 459 from 507 to get 48.
Fetch the next digit (3) from the dividend, attach it to 48 and continue: 483 / 51

Moving on to step 6:
The number 51 fits into 483 9 times, leaving a remainder of 24.
The next digit of our result is 9. 
Result so far: 12199.0
If we subtract 459 from 483, 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 7:
When dividing 240 by 51, we get 4 with a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 12199.4
If we subtract 204 from 240, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 8:
When dividing 360 by 51, we get 7 with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 12199.47
If we take 357 away from 360, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 9:
51 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 12199.47
Subtract 0 from 30 to 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.

Moving on to step 10:
300 divided by 51 is 5 with a remainder of 45.
The next digit of our result is 5. 
Result so far: 12199.4705
Subtract 255 from 300 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 11:
If we divide 450 by 51, we get 8 and a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 12199.47058
If we take 408 away from 450, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 12:
If we divide 420 by 51, we get 8 and a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 12199.470588
Subtracting 408 from 420 leaves us 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.

The final result is 12199.470588 with a remainder of 1.2e-06.
