427438 divided by 39 
Our goal is to divide 427438 by 39.

Advancing to step 1:
39 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 39

Step 2:
The number 39 fits into 42 1 times, leaving a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 39 away from 42, we end up with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 39

Moving on to step 3:
The number 39 fits into 37 0 times, leaving a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 37, we end up with 37.
Append the next digit (4) from the dividend to 37 and continue with: 374 / 39

Let's proceed to step 4:
39 goes into 374 9 times with a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 109.0
The remainder is 23 after subtracting 351 from 374.
Append the next digit (3) from the dividend to 23 and continue with: 233 / 39

Moving on to step 5:
39 goes into 233 5 times with a remainder of 38.
Use 5 as the next digit of our solution. 
Result so far: 1095.0
The remainder is 38 after subtracting 195 from 233.
Include the next digit (8) from the dividend after 38, then repeat: 388 / 39

Step 6:
If we divide 388 by 39, we get 9 and a remainder of 37.
Put 9 as the next digit of the answer. 
Result so far: 10959.0
Subtracting 351 from 388 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 7:
370 divided by 39 is 9 with a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 10959.9
If we subtract 351 from 370, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 8:
The number 39 fits into 190 4 times, leaving a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 10959.94
Subtract 156 from 190 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 9:
340 divided by 39 is 8 with a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 10959.948
Subtract 312 from 340 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 10:
If we divide 280 by 39, we get 7 and a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 10959.9487
Deduct 273 from 280 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 11:
70 divided by 39 is 1 with a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 10959.94871
If we take 39 away from 70, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 12:
When dividing 310 by 39, we get 7 with a remainder of 37.
The next digit of our result is 7. 
Result so far: 10959.948717
The remainder is 37 after subtracting 273 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 13:
39 can be fit into 370 9 times, resulting in a remainder of 19.
The next digit of our result is 9. 
Result so far: 10959.9487179
Deduct 351 from 370 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 14:
39 can be fit into 190 4 times, resulting in a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 10959.94871794
The remainder is 34 after subtracting 156 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final outcome is 10959.94871794, with a leftover of 3.4e-08.
