We're dividing 79788992 by 620 
We want to figure out the number of times 79788992 can be divided by 620.

Let's proceed to step 1:
620 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 620

Moving on to step 2:
The number 620 fits into 79 0 times, leaving a remainder of 79.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 79 after subtracting 0 from 79.
Include the next digit (7) from the dividend after 79, then repeat: 797 / 620

Let's proceed to step 3:
If we divide 797 by 620, we get 1 and a remainder of 177.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 620 from 797 and we're left with 177.
Include the next digit (8) from the dividend after 177, then repeat: 1778 / 620

Let's proceed to step 4:
The number 620 fits into 1778 2 times, leaving a remainder of 538.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 1240 from 1778 and we're left with 538.
Append the next digit (8) from the dividend to 538 and continue with: 5388 / 620

On to step 5:
5388 divided by 620 is 8 with a remainder of 428.
Write down 8 as next digit of the result. 
Result so far: 128.0
The remainder is 428 after subtracting 4960 from 5388.
Include the next digit (9) from the dividend after 428, then repeat: 4289 / 620

On to step 6:
If we divide 4289 by 620, we get 6 and a remainder of 569.
Use 6 as the next digit of our solution. 
Result so far: 1286.0
Subtract 3720 from 4289 to get 569.
Take the next digit (9) from the dividend and append it to 569, then repeat: 5699 / 620

Moving on to step 7:
The number 620 fits into 5699 9 times, leaving a remainder of 119.
The next digit of our result is 9. 
Result so far: 12869.0
If we take 5580 away from 5699, we end up with 119.
Bring next digit (2) of the dividend behind the 119 and repeat the process: 1192 / 620

On to step 8:
When dividing 1192 by 620, we get 1 with a remainder of 572.
The next digit of our result is 1. 
Result so far: 128691.0
Subtract 620 from 1192 to get 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Let's proceed to step 9:
620 goes into 5720 9 times with a remainder of 140.
The number 9 becomes the next digit in our result. 
Result so far: 128691.9
The remainder is 140 after subtracting 5580 from 5720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 10:
620 goes into 1400 2 times with a remainder of 160.
Use 2 as the next digit of our solution. 
Result so far: 128691.92
Subtract 1240 from 1400 to get 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 11:
The number 620 fits into 1600 2 times, leaving a remainder of 360.
Use 2 as the next digit of our solution. 
Result so far: 128691.922
Subtract 1240 from 1600 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Our division results in 128691.922 with a remaining 0.036.
