418237 ÷ 39 
We're looking to find how many times 39 goes into 418237.

Going ahead to step 1:
The number 39 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 39

Advancing to step 2:
39 goes into 41 1 times with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 39 away from 41, we end up with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 39

Going ahead to step 3:
When dividing 28 by 39, we get 0 with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 28, we end up with 28.
Fetch the next digit (2) from the dividend, attach it to 28 and continue: 282 / 39

Moving on to step 4:
39 goes into 282 7 times with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 107.0
The remainder is 9 after subtracting 273 from 282.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 39

Moving on to step 5:
39 goes into 93 2 times with a remainder of 15.
The next digit of our result is 2. 
Result so far: 1072.0
Deduct 78 from 93 and we're left with 15.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 39

Moving on to step 6:
The number 39 fits into 157 4 times, leaving a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 10724.0
Subtract 156 from 157 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
The number 39 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 10724.0
Subtracting 0 from 10 leaves us 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.

Let's proceed to step 8:
39 can be fit into 100 2 times, resulting in a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 10724.02
If we take 78 away from 100, we end up 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.

Advancing to step 9:
39 goes into 220 5 times with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 10724.025
Subtract 195 from 220 to get 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 10:
The number 39 fits into 250 6 times, leaving a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 10724.0256
Deduct 234 from 250 and we're left 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.

Step 11:
160 divided by 39 is 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 10724.02564
Deduct 156 from 160 and we're left with 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 12:
39 goes into 40 1 times with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 10724.025641
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.

Moving on to step 13:
When dividing 10 by 39, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 10724.025641
Subtract 0 from 10 to get 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 14:
When dividing 100 by 39, we get 2 with a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 10724.02564102
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.

The final outcome is 10724.02564102, with a leftover of 2.2e-08.
