We're dividing 616643 by 39 
Our goal is to divide 616643 by 39.

Step 1:
The number 39 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 39

On to step 2:
61 divided by 39 is 1 with a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 39 from 61, we get 22.
Bring next digit (6) of the dividend behind the 22 and repeat the process: 226 / 39

On to step 3:
If we divide 226 by 39, we get 5 and a remainder of 31.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 195 from 226, we get 31.
Fetch the next digit (6) from the dividend, attach it to 31 and continue: 316 / 39

Let's proceed to step 4:
The number 39 fits into 316 8 times, leaving a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 158.0
If we take 312 away from 316, we end up with 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 39

Advancing to step 5:
When dividing 44 by 39, we get 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1581.0
If we take 39 away from 44, we end up with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 39

On to step 6:
When dividing 53 by 39, we get 1 with a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 15811.0
If we take 39 away from 53, 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.

Let's proceed to step 7:
39 goes into 140 3 times with a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 15811.3
Subtract 117 from 140 to 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.

Going ahead to step 8:
39 can be fit into 230 5 times, resulting in a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 15811.35
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.

Advancing to step 9:
If we divide 350 by 39, we get 8 and a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 15811.358
The remainder is 38 after subtracting 312 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 10:
If we divide 380 by 39, we get 9 and a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 15811.3589
If we take 351 away from 380, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 11:
The number 39 fits into 290 7 times, leaving a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 15811.35897
The remainder is 17 after subtracting 273 from 290.
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 12:
When dividing 170 by 39, we get 4 with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 15811.358974
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.

On to step 13:
140 divided by 39 is 3 with a remainder of 23.
The next digit of our result is 3. 
Result so far: 15811.3589743
Subtract 117 from 140 to 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.

Advancing to step 14:
39 goes into 230 5 times with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 15811.35897435
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.

The quotient of the division is 15811.35897435, and the remainder is 3.5e-08.
