630452 divided by 39 
We're looking to find how many times 39 goes into 630452.

On to step 1:
6 divided by 39 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 39

Advancing to step 2:
When dividing 63 by 39, we get 1 with a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 24 after subtracting 39 from 63.
Include the next digit (0) from the dividend after 24, then repeat: 240 / 39

Advancing to step 3:
240 divided by 39 is 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 16.0
The remainder is 6 after subtracting 234 from 240.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 39

Going ahead to step 4:
39 goes into 64 1 times with a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 161.0
Deduct 39 from 64 and we're left with 25.
Fetch the next digit (5) from the dividend, attach it to 25 and continue: 255 / 39

Moving on to step 5:
39 goes into 255 6 times with a remainder of 21.
The number 6 becomes the next digit in our result. 
Result so far: 1616.0
The remainder is 21 after subtracting 234 from 255.
Fetch the next digit (2) from the dividend, attach it to 21 and continue: 212 / 39

On to step 6:
212 divided by 39 is 5 with a remainder of 17.
The next digit of our result is 5. 
Result so far: 16165.0
The remainder is 17 after subtracting 195 from 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
39 can be fit into 170 4 times, resulting in a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 16165.4
The remainder is 14 after subtracting 156 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
The number 39 fits into 140 3 times, leaving a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 16165.43
The remainder is 23 after subtracting 117 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 9:
The number 39 fits into 230 5 times, leaving a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 16165.435
The remainder is 35 after subtracting 195 from 230.
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 10:
The number 39 fits into 350 8 times, leaving a remainder of 38.
Record the quotient 8 as the next digit in the result. 
Result so far: 16165.4358
Subtract 312 from 350 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 11:
The number 39 fits into 380 9 times, leaving a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 16165.43589
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.

On to step 12:
If we divide 290 by 39, we get 7 and a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 16165.435897
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.

Let's proceed to step 13:
If we divide 170 by 39, we get 4 and a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 16165.4358974
Subtracting 156 from 170 leaves us 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.

Step 14:
If we divide 140 by 39, we get 3 and a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 16165.43589743
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.

The final outcome is 16165.43589743, with a leftover of 2.3e-08.
