612448 divided by 39 
Our goal is to divide 612448 by 39.

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

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.
Append the next digit (2) from the dividend to 22 and continue with: 222 / 39

Moving on to step 3:
The number 39 fits into 222 5 times, leaving a remainder of 27.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we take 195 away from 222, we end up with 27.
Append the next digit (4) from the dividend to 27 and continue with: 274 / 39

Going ahead to step 4:
39 goes into 274 7 times with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 157.0
Deduct 273 from 274 and we're left with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 39

Advancing to step 5:
39 can be fit into 14 0 times, resulting in a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 1570.0
Deduct 0 from 14 and we're left with 14.
Include the next digit (8) from the dividend after 14, then repeat: 148 / 39

Going ahead to step 6:
39 can be fit into 148 3 times, resulting in a remainder of 31.
Use 3 as the next digit of our solution. 
Result so far: 15703.0
Subtracting 117 from 148 leaves us 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.

Advancing to step 7:
If we divide 310 by 39, we get 7 and a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 15703.7
If we take 273 away from 310, we end up 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.

Step 8:
370 divided by 39 is 9 with a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 15703.79
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 9:
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: 15703.794
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.

Step 10:
39 goes into 340 8 times with a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 15703.7948
If we subtract 312 from 340, we 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.

Advancing to step 11:
The number 39 fits into 280 7 times, leaving a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 15703.79487
The remainder is 7 after subtracting 273 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 12:
39 goes into 70 1 times with a remainder of 31.
The next digit of our result is 1. 
Result so far: 15703.794871
Subtracting 39 from 70 leaves us 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 13:
If we divide 310 by 39, we get 7 and a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 15703.7948717
Subtracting 273 from 310 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.

Let's proceed to step 14:
370 divided by 39 is 9 with a remainder of 19.
The next digit of our result is 9. 
Result so far: 15703.79487179
If we take 351 away from 370, we end up 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.

The final result is 15703.79487179 with a remainder of 1.9e-08.
