99220655 ÷ 620 
We want to divide 99220655 by 620.

Step 1:
The number 620 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 620

Moving on to step 2:
620 goes into 99 0 times with a remainder of 99.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Append the next digit (2) from the dividend to 99 and continue with: 992 / 620

Advancing to step 3:
The number 620 fits into 992 1 times, leaving a remainder of 372.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 620 from 992 to get 372.
Append the next digit (2) from the dividend to 372 and continue with: 3722 / 620

Moving on to step 4:
3722 divided by 620 is 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we take 3720 away from 3722, we end up with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 620

Step 5:
If we divide 20 by 620, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 160.0
If we take 0 away from 20, we end up with 20.
Bring next digit (6) of the dividend behind the 20 and repeat the process: 206 / 620

Let's proceed to step 6:
206 divided by 620 is 0 with a remainder of 206.
The number 0 becomes the next digit in our result. 
Result so far: 1600.0
Subtract 0 from 206 to get 206.
Take the next digit (5) from the dividend and append it to 206, then repeat: 2065 / 620

Advancing to step 7:
2065 divided by 620 is 3 with a remainder of 205.
Record the quotient 3 as the next digit in the result. 
Result so far: 16003.0
Deduct 1860 from 2065 and we're left with 205.
Append the next digit (5) from the dividend to 205 and continue with: 2055 / 620

Going ahead to step 8:
2055 divided by 620 is 3 with a remainder of 195.
Write down 3 as next digit of the result. 
Result so far: 160033.0
Subtract 1860 from 2055 to get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Step 9:
The number 620 fits into 1950 3 times, leaving a remainder of 90.
The next digit of our result is 3. 
Result so far: 160033.3
If we subtract 1860 from 1950, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 10:
620 can be fit into 900 1 times, resulting in a remainder of 280.
The next digit of our result is 1. 
Result so far: 160033.31
Subtract 620 from 900 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 11:
620 can be fit into 2800 4 times, resulting in a remainder of 320.
Use 4 as the next digit of our solution. 
Result so far: 160033.314
Subtracting 2480 from 2800 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 12:
3200 divided by 620 is 5 with a remainder of 100.
The next digit of our result is 5. 
Result so far: 160033.3145
The remainder is 100 after subtracting 3100 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 13:
When dividing 1000 by 620, we get 1 with a remainder of 380.
Put 1 as the next digit of the answer. 
Result so far: 160033.31451
If we take 620 away from 1000, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 14:
When dividing 3800 by 620, we get 6 with a remainder of 80.
Use 6 as the next digit of our solution. 
Result so far: 160033.314516
If we subtract 3720 from 3800, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 15:
800 divided by 620 is 1 with a remainder of 180.
The next digit of our result is 1. 
Result so far: 160033.3145161
Subtracting 620 from 800 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 16:
1800 divided by 620 is 2 with a remainder of 560.
Write down 2 as next digit of the result. 
Result so far: 160033.31451612
Deduct 1240 from 1800 and we're left 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.

The final result is 160033.31451612 with a remainder of 5.6e-07.
