We're dividing 545429 by 39 
We're looking to find how many times 39 goes into 545429.

Step 1:
39 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 39

Going ahead to step 2:
The number 39 fits into 54 1 times, leaving a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 39 from 54 leaves us with 15.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 39

Step 3:
The number 39 fits into 155 3 times, leaving a remainder of 38.
Write down 3 as next digit of the result. 
Result so far: 13.0
The remainder is 38 after subtracting 117 from 155.
Append the next digit (4) from the dividend to 38 and continue with: 384 / 39

On to step 4:
39 can be fit into 384 9 times, resulting in a remainder of 33.
The number 9 becomes the next digit in our result. 
Result so far: 139.0
If we subtract 351 from 384, we get 33.
Bring next digit (2) of the dividend behind the 33 and repeat the process: 332 / 39

Step 5:
39 goes into 332 8 times with a remainder of 20.
The next digit of our result is 8. 
Result so far: 1398.0
Subtract 312 from 332 to get 20.
Grab the next digit (9) from the dividend, add it to 20, then carry on: 209 / 39

Moving on to step 6:
When dividing 209 by 39, we get 5 with a remainder of 14.
The next digit of our result is 5. 
Result so far: 13985.0
If we subtract 195 from 209, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
39 goes into 140 3 times with a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 13985.3
If we subtract 117 from 140, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 8:
39 goes into 230 5 times with a remainder of 35.
The next digit of our result is 5. 
Result so far: 13985.35
If we subtract 195 from 230, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 9:
350 divided by 39 is 8 with a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 13985.358
Deduct 312 from 350 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 10:
When dividing 380 by 39, we get 9 with a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 13985.3589
Subtract 351 from 380 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 11:
If we divide 290 by 39, we get 7 and a remainder of 17.
The next digit of our result is 7. 
Result so far: 13985.35897
If we take 273 away from 290, 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.

Going ahead to step 12:
170 divided by 39 is 4 with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 13985.358974
If we take 156 away from 170, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 13:
39 goes into 140 3 times with a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 13985.3589743
If we take 117 away from 140, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 14:
39 goes into 230 5 times with a remainder of 35.
The next digit of our result is 5. 
Result so far: 13985.35897435
Subtract 195 from 230 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Our division results in 13985.35897435 with a remaining 3.5e-08.
