We're dividing 615429 by 39 
We're looking to find how many times 39 goes into 615429.

On to step 1:
The number 39 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 39

Let's proceed to step 2:
39 can be fit into 61 1 times, resulting in a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 22 after subtracting 39 from 61.
Fetch the next digit (5) from the dividend, attach it to 22 and continue: 225 / 39

Going ahead to step 3:
39 goes into 225 5 times with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtracting 195 from 225 leaves us with 30.
Grab the next digit (4) from the dividend, add it to 30, then carry on: 304 / 39

Moving on to step 4:
39 goes into 304 7 times with a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 157.0
The remainder is 31 after subtracting 273 from 304.
Fetch the next digit (2) from the dividend, attach it to 31 and continue: 312 / 39

Moving on to step 5:
39 can be fit into 312 8 times, resulting in a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 1578.0
Subtracting 312 from 312 leaves us with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 39

Step 6:
The number 39 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 15780.0
Deduct 0 from 9 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
If we divide 90 by 39, we get 2 and a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 15780.2
Subtracting 78 from 90 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 8:
39 can be fit into 120 3 times, resulting in a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 15780.23
Deduct 117 from 120 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 9:
The number 39 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 15780.23
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
When dividing 300 by 39, we get 7 with a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 15780.2307
Subtract 273 from 300 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 11:
The number 39 fits into 270 6 times, leaving a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 15780.23076
If we take 234 away from 270, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 12:
360 divided by 39 is 9 with a remainder of 9.
The next digit of our result is 9. 
Result so far: 15780.230769
Subtracting 351 from 360 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 13:
39 goes into 90 2 times with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 15780.2307692
Subtract 78 from 90 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 14:
If we divide 120 by 39, we get 3 and a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 15780.23076923
If we subtract 117 from 120, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

After the division, we end up with 15780.23076923 and a remainder of 3e-09.
