We look at the division of 642649 by 39 
We want to figure out the number of times 642649 can be divided by 39.

Let's proceed to step 1:
39 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 39

Going ahead to step 2:
When dividing 64 by 39, we get 1 with a remainder of 25.
The next digit of our result is 1. 
Result so far: 1.0
If we take 39 away from 64, we end up with 25.
Fetch the next digit (2) from the dividend, attach it to 25 and continue: 252 / 39

Step 3:
If we divide 252 by 39, we get 6 and a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 16.0
Deduct 234 from 252 and we're left with 18.
Bring next digit (6) of the dividend behind the 18 and repeat the process: 186 / 39

Step 4:
The number 39 fits into 186 4 times, leaving a remainder of 30.
Record the quotient 4 as the next digit in the result. 
Result so far: 164.0
The remainder is 30 after subtracting 156 from 186.
Take the next digit (4) from the dividend and append it to 30, then repeat: 304 / 39

Let's proceed to step 5:
If we divide 304 by 39, we get 7 and a remainder of 31.
The next digit of our result is 7. 
Result so far: 1647.0
If we take 273 away from 304, we end up with 31.
Append the next digit (9) from the dividend to 31 and continue with: 319 / 39

Let's proceed to step 6:
39 can be fit into 319 8 times, resulting in a remainder of 7.
The next digit of our result is 8. 
Result so far: 16478.0
If we subtract 312 from 319, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
When dividing 70 by 39, we get 1 with a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 16478.1
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.

Let's proceed to step 8:
39 can be fit into 310 7 times, resulting in a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 16478.17
Subtract 273 from 310 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 9:
39 goes into 370 9 times with a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 16478.179
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.

Step 10:
If we divide 190 by 39, we get 4 and a remainder of 34.
The next digit of our result is 4. 
Result so far: 16478.1794
If we subtract 156 from 190, we 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.

Going ahead to step 11:
340 divided by 39 is 8 with a remainder of 28.
The next digit of our result is 8. 
Result so far: 16478.17948
Subtract 312 from 340 to 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.

Moving on to step 12:
39 can be fit into 280 7 times, resulting in a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 16478.179487
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.

Moving on to step 13:
39 goes into 70 1 times with a remainder of 31.
The next digit of our result is 1. 
Result so far: 16478.1794871
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.

Going ahead to step 14:
39 can be fit into 310 7 times, resulting in a remainder of 37.
The next digit of our result is 7. 
Result so far: 16478.17948717
Deduct 273 from 310 and we're left 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.

Our division results in 16478.17948717 with a remaining 3.7e-08.
