We look at the division of 39645390 by 61 
Our goal is to divide 39645390 by 61.

On to step 1:
61 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 61

Going ahead to step 2:
When dividing 39 by 61, we get 0 with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Fetch the next digit (6) from the dividend, attach it to 39 and continue: 396 / 61

Going ahead to step 3:
If we divide 396 by 61, we get 6 and a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 366 from 396, we get 30.
Grab the next digit (4) from the dividend, add it to 30, then carry on: 304 / 61

Let's proceed to step 4:
61 can be fit into 304 4 times, resulting in a remainder of 60.
Put 4 as the next digit of the answer. 
Result so far: 64.0
Deduct 244 from 304 and we're left with 60.
Append the next digit (5) from the dividend to 60 and continue with: 605 / 61

Advancing to step 5:
When dividing 605 by 61, we get 9 with a remainder of 56.
Use 9 as the next digit of our solution. 
Result so far: 649.0
Subtracting 549 from 605 leaves us with 56.
Grab the next digit (3) from the dividend, add it to 56, then carry on: 563 / 61

Advancing to step 6:
The number 61 fits into 563 9 times, leaving a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 6499.0
Subtracting 549 from 563 leaves us with 14.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 61

Step 7:
If we divide 149 by 61, we get 2 and a remainder of 27.
Put 2 as the next digit of the answer. 
Result so far: 64992.0
The remainder is 27 after subtracting 122 from 149.
Fetch the next digit (0) from the dividend, attach it to 27 and continue: 270 / 61

Advancing to step 8:
61 goes into 270 4 times with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 649924.0
The remainder is 26 after subtracting 244 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 9:
If we divide 260 by 61, we get 4 and a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 649924.4
Deduct 244 from 260 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 10:
160 divided by 61 is 2 with a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 649924.42
Deduct 122 from 160 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 11:
380 divided by 61 is 6 with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 649924.426
If we take 366 away from 380, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 12:
140 divided by 61 is 2 with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 649924.4262
Subtracting 122 from 140 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 13:
61 goes into 180 2 times with a remainder of 58.
Record the quotient 2 as the next digit in the result. 
Result so far: 649924.42622
Subtracting 122 from 180 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Our division results in 649924.42622 with a remaining 5.8e-05.
