We're dividing 20115555 by 620 
We want to figure out the number of times 20115555 can be divided by 620.

Moving on to step 1:
If we divide 2 by 620, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 620

Let's proceed to step 2:
If we divide 20 by 620, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Include the next digit (1) from the dividend after 20, then repeat: 201 / 620

Moving on to step 3:
620 goes into 201 0 times with a remainder of 201.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 201 and we're left with 201.
Append the next digit (1) from the dividend to 201 and continue with: 2011 / 620

Moving on to step 4:
620 goes into 2011 3 times with a remainder of 151.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 1860 from 2011 to get 151.
Bring next digit (5) of the dividend behind the 151 and repeat the process: 1515 / 620

Advancing to step 5:
If we divide 1515 by 620, we get 2 and a remainder of 275.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
Subtracting 1240 from 1515 leaves us with 275.
Grab the next digit (5) from the dividend, add it to 275, then carry on: 2755 / 620

Advancing to step 6:
The number 620 fits into 2755 4 times, leaving a remainder of 275.
Record the quotient 4 as the next digit in the result. 
Result so far: 324.0
The remainder is 275 after subtracting 2480 from 2755.
Fetch the next digit (5) from the dividend, attach it to 275 and continue: 2755 / 620

Going ahead to step 7:
620 goes into 2755 4 times with a remainder of 275.
Record the quotient 4 as the next digit in the result. 
Result so far: 3244.0
Subtract 2480 from 2755 to get 275.
Grab the next digit (5) from the dividend, add it to 275, then carry on: 2755 / 620

On to step 8:
620 goes into 2755 4 times with a remainder of 275.
Record the quotient 4 as the next digit in the result. 
Result so far: 32444.0
If we take 2480 away from 2755, we end up with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Going ahead to step 9:
2750 divided by 620 is 4 with a remainder of 270.
Write down 4 as next digit of the result. 
Result so far: 32444.4
Deduct 2480 from 2750 and we're left with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Let's proceed to step 10:
620 can be fit into 2700 4 times, resulting in a remainder of 220.
Use 4 as the next digit of our solution. 
Result so far: 32444.44
Deduct 2480 from 2700 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

In conclusion, the division gives 32444.44 with a balance of 0.22.
