We're dividing 66472612 by 620 
Let's see how many times 620 fits into 66472612.

Step 1:
When dividing 6 by 620, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 620

Going ahead to step 2:
If we divide 66 by 620, we get 0 and a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Grab the next digit (4) from the dividend, add it to 66, then carry on: 664 / 620

Step 3:
620 can be fit into 664 1 times, resulting in a remainder of 44.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 620 from 664 to get 44.
Append the next digit (7) from the dividend to 44 and continue with: 447 / 620

Step 4:
When dividing 447 by 620, we get 0 with a remainder of 447.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 447, we end up with 447.
Take the next digit (2) from the dividend and append it to 447, then repeat: 4472 / 620

Moving on to step 5:
If we divide 4472 by 620, we get 7 and a remainder of 132.
Use 7 as the next digit of our solution. 
Result so far: 107.0
Deduct 4340 from 4472 and we're left with 132.
Include the next digit (6) from the dividend after 132, then repeat: 1326 / 620

Step 6:
The number 620 fits into 1326 2 times, leaving a remainder of 86.
The next digit of our result is 2. 
Result so far: 1072.0
If we subtract 1240 from 1326, we get 86.
Fetch the next digit (1) from the dividend, attach it to 86 and continue: 861 / 620

Moving on to step 7:
620 goes into 861 1 times with a remainder of 241.
Use 1 as the next digit of our solution. 
Result so far: 10721.0
Subtracting 620 from 861 leaves us with 241.
Include the next digit (2) from the dividend after 241, then repeat: 2412 / 620

On to step 8:
When dividing 2412 by 620, we get 3 with a remainder of 552.
Write down 3 as next digit of the result. 
Result so far: 107213.0
The remainder is 552 after subtracting 1860 from 2412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Let's proceed to step 9:
The number 620 fits into 5520 8 times, leaving a remainder of 560.
Use 8 as the next digit of our solution. 
Result so far: 107213.8
Subtracting 4960 from 5520 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

On to step 10:
5600 divided by 620 is 9 with a remainder of 20.
The next digit of our result is 9. 
Result so far: 107213.89
If we subtract 5580 from 5600, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
If we divide 200 by 620, we get 0 and a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 107213.89
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 12:
The number 620 fits into 2000 3 times, leaving a remainder of 140.
The next digit of our result is 3. 
Result so far: 107213.8903
Subtract 1860 from 2000 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 13:
620 goes into 1400 2 times with a remainder of 160.
Record the quotient 2 as the next digit in the result. 
Result so far: 107213.89032
Subtracting 1240 from 1400 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 14:
When dividing 1600 by 620, we get 2 with a remainder of 360.
Put 2 as the next digit of the answer. 
Result so far: 107213.890322
Deduct 1240 from 1600 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

In conclusion, the division gives 107213.890322 with a balance of 3.6e-05.
