We're dividing 85661265 by 620 
We want to figure out the number of times 85661265 can be divided by 620.

Going ahead to step 1:
8 divided by 620 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 620

Going ahead to step 2:
The number 620 fits into 85 0 times, leaving a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Fetch the next digit (6) from the dividend, attach it to 85 and continue: 856 / 620

Moving on to step 3:
620 goes into 856 1 times with a remainder of 236.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 620 from 856 to get 236.
Take the next digit (6) from the dividend and append it to 236, then repeat: 2366 / 620

Step 4:
The number 620 fits into 2366 3 times, leaving a remainder of 506.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we subtract 1860 from 2366, we get 506.
Append the next digit (1) from the dividend to 506 and continue with: 5061 / 620

Going ahead to step 5:
If we divide 5061 by 620, we get 8 and a remainder of 101.
Write down 8 as next digit of the result. 
Result so far: 138.0
The remainder is 101 after subtracting 4960 from 5061.
Append the next digit (2) from the dividend to 101 and continue with: 1012 / 620

Let's proceed to step 6:
620 can be fit into 1012 1 times, resulting in a remainder of 392.
The number 1 becomes the next digit in our result. 
Result so far: 1381.0
The remainder is 392 after subtracting 620 from 1012.
Append the next digit (6) from the dividend to 392 and continue with: 3926 / 620

Going ahead to step 7:
620 goes into 3926 6 times with a remainder of 206.
The number 6 becomes the next digit in our result. 
Result so far: 13816.0
If we subtract 3720 from 3926, we get 206.
Include the next digit (5) from the dividend after 206, then repeat: 2065 / 620

Going ahead to step 8:
The number 620 fits into 2065 3 times, leaving a remainder of 205.
Write down 3 as next digit of the result. 
Result so far: 138163.0
If we subtract 1860 from 2065, we get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Advancing to step 9:
If we divide 2050 by 620, we get 3 and a remainder of 190.
Put 3 as the next digit of the answer. 
Result so far: 138163.3
Subtracting 1860 from 2050 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 10:
620 can be fit into 1900 3 times, resulting in a remainder of 40.
Use 3 as the next digit of our solution. 
Result so far: 138163.33
Subtracting 1860 from 1900 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 138163.33, with a leftover of 0.04.
