400936 ÷ 39 
We're looking to find how many times 39 goes into 400936.

Going ahead to step 1:
The number 39 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 39

Advancing to step 2:
The number 39 fits into 40 1 times, leaving a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 39 from 40, we get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 39

Moving on to step 3:
10 divided by 39 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 10 and we're left with 10.
Fetch the next digit (9) from the dividend, attach it to 10 and continue: 109 / 39

Advancing to step 4:
39 can be fit into 109 2 times, resulting in a remainder of 31.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
Subtracting 78 from 109 leaves us with 31.
Include the next digit (3) from the dividend after 31, then repeat: 313 / 39

Step 5:
The number 39 fits into 313 8 times, leaving a remainder of 1.
The next digit of our result is 8. 
Result so far: 1028.0
If we take 312 away from 313, we end up with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 39

Step 6:
16 divided by 39 is 0 with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 10280.0
If we subtract 0 from 16, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
39 can be fit into 160 4 times, resulting in a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 10280.4
If we subtract 156 from 160, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
When dividing 40 by 39, we get 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 10280.41
The remainder is 1 after subtracting 39 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
When dividing 10 by 39, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 10280.41
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
When dividing 100 by 39, we get 2 with a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 10280.4102
The remainder is 22 after subtracting 78 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 11:
39 can be fit into 220 5 times, resulting in a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 10280.41025
Subtracting 195 from 220 leaves us 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.

On to step 12:
39 can be fit into 250 6 times, resulting in a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 10280.410256
If we take 234 away from 250, we end up 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.

On to step 13:
The number 39 fits into 160 4 times, leaving a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 10280.4102564
The remainder is 4 after subtracting 156 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 14:
40 divided by 39 is 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 10280.41025641
If we take 39 away from 40, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The quotient of the division is 10280.41025641, and the remainder is 1e-09.
