390403 ÷ 61 
Our goal is to divide 390403 by 61.

On to step 1:
61 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 61

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
Subtract 0 from 39 to get 39.
Bring next digit (0) of the dividend behind the 39 and repeat the process: 390 / 61

On to step 3:
61 goes into 390 6 times with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 24 after subtracting 366 from 390.
Append the next digit (4) from the dividend to 24 and continue with: 244 / 61

Step 4:
If we divide 244 by 61, we get 4 and a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 64.0
If we subtract 244 from 244, we get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 61

Let's proceed to step 5:
The number 61 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 640.0
Subtract 0 from 0 to get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 61

Going ahead to step 6:
The number 61 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 6400.0
Deduct 0 from 3 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
The number 61 fits into 30 0 times, leaving a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 6400.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
The number 61 fits into 300 4 times, leaving a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 6400.04
If we take 244 away from 300, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 9:
61 goes into 560 9 times with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 6400.049
Deduct 549 from 560 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 10:
61 goes into 110 1 times with a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 6400.0491
Subtract 61 from 110 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 11:
61 can be fit into 490 8 times, resulting in a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 6400.04918
The remainder is 2 after subtracting 488 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 12:
61 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 6400.04918
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 13:
61 can be fit into 200 3 times, resulting in a remainder of 17.
The next digit of our result is 3. 
Result so far: 6400.0491803
Subtracting 183 from 200 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 14:
If we divide 170 by 61, we get 2 and a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 6400.04918032
Subtract 122 from 170 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Our division results in 6400.04918032 with a remaining 4.8e-08.
