99343339 divided by 620 
We want to figure out the number of times 99343339 can be divided by 620.

Step 1:
The number 620 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 620

Let's proceed to step 2:
When dividing 99 by 620, we get 0 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.
Fetch the next digit (3) from the dividend, attach it to 99 and continue: 993 / 620

Step 3:
620 can be fit into 993 1 times, resulting in a remainder of 373.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 373 after subtracting 620 from 993.
Bring next digit (4) of the dividend behind the 373 and repeat the process: 3734 / 620

Advancing to step 4:
620 can be fit into 3734 6 times, resulting in a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we take 3720 away from 3734, we end up with 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 620

Advancing to step 5:
620 goes into 143 0 times with a remainder of 143.
The number 0 becomes the next digit in our result. 
Result so far: 160.0
Subtracting 0 from 143 leaves us with 143.
Grab the next digit (3) from the dividend, add it to 143, then carry on: 1433 / 620

Step 6:
When dividing 1433 by 620, we get 2 with a remainder of 193.
Use 2 as the next digit of our solution. 
Result so far: 1602.0
Subtract 1240 from 1433 to get 193.
Bring next digit (3) of the dividend behind the 193 and repeat the process: 1933 / 620

Step 7:
620 goes into 1933 3 times with a remainder of 73.
The number 3 becomes the next digit in our result. 
Result so far: 16023.0
If we subtract 1860 from 1933, we get 73.
Include the next digit (9) from the dividend after 73, then repeat: 739 / 620

On to step 8:
When dividing 739 by 620, we get 1 with a remainder of 119.
The number 1 becomes the next digit in our result. 
Result so far: 160231.0
Subtract 620 from 739 to get 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Moving on to step 9:
When dividing 1190 by 620, we get 1 with a remainder of 570.
Put 1 as the next digit of the answer. 
Result so far: 160231.1
If we take 620 away from 1190, we end up with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Going ahead to step 10:
When dividing 5700 by 620, we get 9 with a remainder of 120.
Put 9 as the next digit of the answer. 
Result so far: 160231.19
Subtract 5580 from 5700 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 11:
The number 620 fits into 1200 1 times, leaving a remainder of 580.
Use 1 as the next digit of our solution. 
Result so far: 160231.191
Deduct 620 from 1200 and we're left with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Advancing to step 12:
5800 divided by 620 is 9 with a remainder of 220.
Put 9 as the next digit of the answer. 
Result so far: 160231.1919
If we take 5580 away from 5800, we end up 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.

Moving on to step 13:
The number 620 fits into 2200 3 times, leaving a remainder of 340.
Use 3 as the next digit of our solution. 
Result so far: 160231.19193
The remainder is 340 after subtracting 1860 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 14:
620 can be fit into 3400 5 times, resulting in a remainder of 300.
The next digit of our result is 5. 
Result so far: 160231.191935
The remainder is 300 after subtracting 3100 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 15:
If we divide 3000 by 620, we get 4 and a remainder of 520.
The number 4 becomes the next digit in our result. 
Result so far: 160231.1919354
Subtracting 2480 from 3000 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 16:
If we divide 5200 by 620, we get 8 and a remainder of 240.
The number 8 becomes the next digit in our result. 
Result so far: 160231.19193548
If we take 4960 away from 5200, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

The final result is 160231.19193548 with a remainder of 2.4e-07.
