We look at the division of 398409 by 61 
Let's see how many times 61 fits into 398409.

Advancing to step 1:
The number 61 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 61

Moving on to step 2:
61 can be fit into 39 0 times, resulting in a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Grab the next digit (8) from the dividend, add it to 39, then carry on: 398 / 61

Advancing to step 3:
61 can be fit into 398 6 times, resulting in a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 366 away from 398, we end up with 32.
Bring next digit (4) of the dividend behind the 32 and repeat the process: 324 / 61

Advancing to step 4:
The number 61 fits into 324 5 times, leaving a remainder of 19.
The next digit of our result is 5. 
Result so far: 65.0
Subtract 305 from 324 to get 19.
Append the next digit (0) from the dividend to 19 and continue with: 190 / 61

Let's proceed to step 5:
61 can be fit into 190 3 times, resulting in a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 653.0
Subtract 183 from 190 to get 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 61

Advancing to step 6:
When dividing 79 by 61, we get 1 with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 6531.0
Subtract 61 from 79 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 7:
61 can be fit into 180 2 times, resulting in a remainder of 58.
Write down 2 as next digit of the result. 
Result so far: 6531.2
Subtract 122 from 180 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 8:
If we divide 580 by 61, we get 9 and a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 6531.29
Subtract 549 from 580 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 9:
61 can be fit into 310 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 6531.295
The remainder is 5 after subtracting 305 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 10:
61 can be fit into 50 0 times, resulting in a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 6531.295
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 11:
The number 61 fits into 500 8 times, leaving a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 6531.29508
Subtract 488 from 500 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 12:
If we divide 120 by 61, we get 1 and a remainder of 59.
Put 1 as the next digit of the answer. 
Result so far: 6531.295081
Subtracting 61 from 120 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 13:
The number 61 fits into 590 9 times, leaving a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 6531.2950819
Subtract 549 from 590 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 14:
The number 61 fits into 410 6 times, leaving a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 6531.29508196
If we subtract 366 from 410, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final result is 6531.29508196 with a remainder of 4.4e-08.
