We look at the division of 390409 by 61 
Our goal is to divide 390409 by 61.

Step 1:
61 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 61

Going ahead to step 2:
39 divided by 61 is 0 with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Grab the next digit (0) from the dividend, add it to 39, then carry on: 390 / 61

Let's proceed to step 3:
390 divided by 61 is 6 with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 366 from 390, we get 24.
Take the next digit (4) from the dividend and append it to 24, then repeat: 244 / 61

Advancing to step 4:
When dividing 244 by 61, we get 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 64.0
Subtracting 244 from 244 leaves us with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 61

Moving on to step 5:
61 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 640.0
If we subtract 0 from 0, we get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 61

On to step 6:
61 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 6400.0
The remainder is 9 after subtracting 0 from 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
If we divide 90 by 61, we get 1 and a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 6400.1
If we take 61 away from 90, we end up 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.

On to step 8:
61 can be fit into 290 4 times, resulting in a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 6400.14
If we subtract 244 from 290, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 9:
61 can be fit into 460 7 times, resulting in a remainder of 33.
The next digit of our result is 7. 
Result so far: 6400.147
If we subtract 427 from 460, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 10:
The number 61 fits into 330 5 times, leaving a remainder of 25.
The next digit of our result is 5. 
Result so far: 6400.1475
If we take 305 away from 330, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 11:
When dividing 250 by 61, we get 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 6400.14754
Subtract 244 from 250 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 12:
When dividing 60 by 61, we get 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 6400.14754
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 13:
61 goes into 600 9 times with a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 6400.1475409
Subtract 549 from 600 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 14:
61 goes into 510 8 times with a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 6400.14754098
Deduct 488 from 510 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 6400.14754098 with a remainder of 2.2e-08.
