We look at the division of 81869396 by 620 
We're looking to find how many times 620 goes into 81869396.

Let's proceed to step 1:
The number 620 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 620

Let's proceed to step 2:
620 goes into 81 0 times with a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Fetch the next digit (8) from the dividend, attach it to 81 and continue: 818 / 620

On to step 3:
The number 620 fits into 818 1 times, leaving a remainder of 198.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 620 from 818, we get 198.
Take the next digit (6) from the dividend and append it to 198, then repeat: 1986 / 620

Step 4:
The number 620 fits into 1986 3 times, leaving a remainder of 126.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we take 1860 away from 1986, we end up with 126.
Grab the next digit (9) from the dividend, add it to 126, then carry on: 1269 / 620

Moving on to step 5:
1269 divided by 620 is 2 with a remainder of 29.
Record the quotient 2 as the next digit in the result. 
Result so far: 132.0
Subtracting 1240 from 1269 leaves us with 29.
Grab the next digit (3) from the dividend, add it to 29, then carry on: 293 / 620

On to step 6:
293 divided by 620 is 0 with a remainder of 293.
The next digit of our result is 0. 
Result so far: 1320.0
If we subtract 0 from 293, we get 293.
Grab the next digit (9) from the dividend, add it to 293, then carry on: 2939 / 620

Let's proceed to step 7:
2939 divided by 620 is 4 with a remainder of 459.
The next digit of our result is 4. 
Result so far: 13204.0
Subtracting 2480 from 2939 leaves us with 459.
Include the next digit (6) from the dividend after 459, then repeat: 4596 / 620

On to step 8:
620 goes into 4596 7 times with a remainder of 256.
The number 7 becomes the next digit in our result. 
Result so far: 132047.0
The remainder is 256 after subtracting 4340 from 4596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 9:
When dividing 2560 by 620, we get 4 with a remainder of 80.
The next digit of our result is 4. 
Result so far: 132047.4
The remainder is 80 after subtracting 2480 from 2560.
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 10:
620 can be fit into 800 1 times, resulting in a remainder of 180.
Put 1 as the next digit of the answer. 
Result so far: 132047.41
Deduct 620 from 800 and we're left 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.

Step 11:
620 can be fit into 1800 2 times, resulting in a remainder of 560.
Record the quotient 2 as the next digit in the result. 
Result so far: 132047.412
If we subtract 1240 from 1800, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 12:
5600 divided by 620 is 9 with a remainder of 20.
The next digit of our result is 9. 
Result so far: 132047.4129
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.

Let's proceed to step 13:
200 divided by 620 is 0 with a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 132047.4129
Subtract 0 from 200 to 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.

Let's proceed to step 14:
620 can be fit into 2000 3 times, resulting in a remainder of 140.
Write down 3 as next digit of the result. 
Result so far: 132047.412903
The remainder is 140 after subtracting 1860 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 15:
The number 620 fits into 1400 2 times, leaving a remainder of 160.
Put 2 as the next digit of the answer. 
Result so far: 132047.4129032
The remainder is 160 after subtracting 1240 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 16:
620 goes into 1600 2 times with a remainder of 360.
The number 2 becomes the next digit in our result. 
Result so far: 132047.41290322
Subtracting 1240 from 1600 leaves us 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.

The final outcome is 132047.41290322, with a leftover of 3.6e-07.
