We're dividing 38640579 by 61 
We want to divide 38640579 by 61.

On to step 1:
If we divide 3 by 61, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 61

Advancing to step 2:
The number 61 fits into 38 0 times, leaving a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Take the next digit (6) from the dividend and append it to 38, then repeat: 386 / 61

Step 3:
61 goes into 386 6 times with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 366 from 386 leaves us with 20.
Bring next digit (4) of the dividend behind the 20 and repeat the process: 204 / 61

Advancing to step 4:
The number 61 fits into 204 3 times, leaving a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 63.0
Subtract 183 from 204 to get 21.
Take the next digit (0) from the dividend and append it to 21, then repeat: 210 / 61

Going ahead to step 5:
When dividing 210 by 61, we get 3 with a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 633.0
The remainder is 27 after subtracting 183 from 210.
Include the next digit (5) from the dividend after 27, then repeat: 275 / 61

Advancing to step 6:
The number 61 fits into 275 4 times, leaving a remainder of 31.
Use 4 as the next digit of our solution. 
Result so far: 6334.0
Subtract 244 from 275 to get 31.
Bring next digit (7) of the dividend behind the 31 and repeat the process: 317 / 61

Going ahead to step 7:
If we divide 317 by 61, we get 5 and a remainder of 12.
Write down 5 as next digit of the result. 
Result so far: 63345.0
If we subtract 305 from 317, we get 12.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 61

Moving on to step 8:
When dividing 129 by 61, we get 2 with a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 633452.0
Deduct 122 from 129 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 9:
61 can be fit into 70 1 times, resulting in a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 633452.1
If we take 61 away from 70, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 10:
61 goes into 90 1 times with a remainder of 29.
The next digit of our result is 1. 
Result so far: 633452.11
Subtracting 61 from 90 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final outcome is 633452.11, with a leftover of 0.029.
