641859 divided by 39 
Let's see how many times 39 fits into 641859.

Going ahead to step 1:
When dividing 6 by 39, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 39

Advancing to step 2:
If we divide 64 by 39, we get 1 and a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 39 away from 64, we end up with 25.
Grab the next digit (1) from the dividend, add it to 25, then carry on: 251 / 39

Going ahead to step 3:
251 divided by 39 is 6 with a remainder of 17.
The next digit of our result is 6. 
Result so far: 16.0
Subtract 234 from 251 to get 17.
Take the next digit (8) from the dividend and append it to 17, then repeat: 178 / 39

Advancing to step 4:
If we divide 178 by 39, we get 4 and a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 164.0
If we take 156 away from 178, we end up with 22.
Bring next digit (5) of the dividend behind the 22 and repeat the process: 225 / 39

On to step 5:
225 divided by 39 is 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 1645.0
If we subtract 195 from 225, we get 30.
Bring next digit (9) of the dividend behind the 30 and repeat the process: 309 / 39

Step 6:
The number 39 fits into 309 7 times, leaving a remainder of 36.
Put 7 as the next digit of the answer. 
Result so far: 16457.0
If we subtract 273 from 309, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 7:
When dividing 360 by 39, we get 9 with a remainder of 9.
The next digit of our result is 9. 
Result so far: 16457.9
Deduct 351 from 360 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.

Going ahead to step 8:
39 goes into 90 2 times with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 16457.92
If we take 78 away from 90, we end up 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.

On to step 9:
120 divided by 39 is 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 16457.923
Subtracting 117 from 120 leaves us 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.

Let's proceed to step 10:
The number 39 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 16457.923
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 11:
The number 39 fits into 300 7 times, leaving a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 16457.92307
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.

Going ahead to step 12:
39 goes into 270 6 times with a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 16457.923076
If we subtract 234 from 270, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 13:
If we divide 360 by 39, we get 9 and a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 16457.9230769
If we take 351 away from 360, we end up 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.

Going ahead to step 14:
The number 39 fits into 90 2 times, leaving a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 16457.92307692
Deduct 78 from 90 and we're left 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.

The quotient of the division is 16457.92307692, and the remainder is 1.2e-08.
