We're dividing 624180 by 51 
We want to figure out the number of times 624180 can be divided by 51.

Step 1:
When dividing 6 by 51, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 51

Advancing to step 2:
The number 51 fits into 62 1 times, leaving a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 51 from 62, we get 11.
Take the next digit (4) from the dividend and append it to 11, then repeat: 114 / 51

On to step 3:
When dividing 114 by 51, we get 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 102 from 114 leaves us with 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 51

Step 4:
The number 51 fits into 121 2 times, leaving a remainder of 19.
The next digit of our result is 2. 
Result so far: 122.0
If we take 102 away from 121, we end up with 19.
Append the next digit (8) from the dividend to 19 and continue with: 198 / 51

Moving on to step 5:
51 goes into 198 3 times with a remainder of 45.
Write down 3 as next digit of the result. 
Result so far: 1223.0
If we take 153 away from 198, we end up with 45.
Append the next digit (0) from the dividend to 45 and continue with: 450 / 51

On to step 6:
51 can be fit into 450 8 times, resulting in a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 12238.0
If we subtract 408 from 450, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 7:
51 goes into 420 8 times with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 12238.8
Subtract 408 from 420 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
51 can be fit into 120 2 times, resulting in a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 12238.82
If we subtract 102 from 120, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 9:
The number 51 fits into 180 3 times, leaving a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 12238.823
Deduct 153 from 180 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 10:
If we divide 270 by 51, we get 5 and a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 12238.8235
The remainder is 15 after subtracting 255 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 11:
The number 51 fits into 150 2 times, leaving a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 12238.82352
Deduct 102 from 150 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 12:
51 goes into 480 9 times with a remainder of 21.
The next digit of our result is 9. 
Result so far: 12238.823529
Subtract 459 from 480 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 13:
The number 51 fits into 210 4 times, leaving a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 12238.8235294
Deduct 204 from 210 and we're left 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 14:
The number 51 fits into 60 1 times, leaving a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 12238.82352941
Deduct 51 from 60 and we're left 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.

Our division results in 12238.82352941 with a remaining 9e-09.
