403639 ÷ 61 
We want to divide 403639 by 61.

Advancing to step 1:
The number 61 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 61

Advancing to step 2:
If we divide 40 by 61, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Fetch the next digit (3) from the dividend, attach it to 40 and continue: 403 / 61

Moving on to step 3:
61 goes into 403 6 times with a remainder of 37.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 366 away from 403, we end up with 37.
Include the next digit (6) from the dividend after 37, then repeat: 376 / 61

Advancing to step 4:
61 can be fit into 376 6 times, resulting in a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 66.0
If we take 366 away from 376, we end up with 10.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 61

Let's proceed to step 5:
103 divided by 61 is 1 with a remainder of 42.
The next digit of our result is 1. 
Result so far: 661.0
Subtracting 61 from 103 leaves us with 42.
Include the next digit (9) from the dividend after 42, then repeat: 429 / 61

On to step 6:
429 divided by 61 is 7 with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 6617.0
Subtract 427 from 429 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
61 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 6617.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
61 can be fit into 200 3 times, resulting in a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 6617.03
If we take 183 away from 200, we end up 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.

On to step 9:
The number 61 fits into 170 2 times, leaving a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 6617.032
Deduct 122 from 170 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 10:
When dividing 480 by 61, we get 7 with a remainder of 53.
The next digit of our result is 7. 
Result so far: 6617.0327
If we subtract 427 from 480, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 11:
530 divided by 61 is 8 with a remainder of 42.
The next digit of our result is 8. 
Result so far: 6617.03278
Subtract 488 from 530 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 12:
If we divide 420 by 61, we get 6 and a remainder of 54.
Use 6 as the next digit of our solution. 
Result so far: 6617.032786
If we subtract 366 from 420, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 13:
If we divide 540 by 61, we get 8 and a remainder of 52.
The next digit of our result is 8. 
Result so far: 6617.0327868
If we take 488 away from 540, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 14:
520 divided by 61 is 8 with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 6617.03278688
The remainder is 32 after subtracting 488 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 6617.03278688, and the remainder is 3.2e-08.
