We're dividing 159719 by 39 
We want to figure out the number of times 159719 can be divided by 39.

On to step 1:
1 divided by 39 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 39

Let's proceed to step 2:
If we divide 15 by 39, we get 0 and a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 39

Advancing to step 3:
159 divided by 39 is 4 with a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 3 after subtracting 156 from 159.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 39

Going ahead to step 4:
The number 39 fits into 37 0 times, leaving a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
If we subtract 0 from 37, we get 37.
Bring next digit (1) of the dividend behind the 37 and repeat the process: 371 / 39

On to step 5:
371 divided by 39 is 9 with a remainder of 20.
Record the quotient 9 as the next digit in the result. 
Result so far: 409.0
Subtracting 351 from 371 leaves us with 20.
Grab the next digit (9) from the dividend, add it to 20, then carry on: 209 / 39

Moving on to step 6:
The number 39 fits into 209 5 times, leaving a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 4095.0
Subtracting 195 from 209 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.

Advancing to step 7:
When dividing 140 by 39, we get 3 with a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 4095.3
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.

Let's proceed to step 8:
The number 39 fits into 230 5 times, leaving a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 4095.35
Deduct 195 from 230 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 9:
39 goes into 350 8 times with a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 4095.358
Subtracting 312 from 350 leaves us with 38.
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:
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: 4095.3589
The remainder is 29 after subtracting 351 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 11:
290 divided by 39 is 7 with a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 4095.35897
Subtracting 273 from 290 leaves us 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.

On to step 12:
39 can be fit into 170 4 times, resulting in a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 4095.358974
Deduct 156 from 170 and we're left 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 13:
39 can be fit into 140 3 times, resulting in a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 4095.3589743
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.

Moving on to step 14:
If we divide 230 by 39, we get 5 and a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 4095.35897435
Deduct 195 from 230 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Our division results in 4095.35897435 with a remaining 3.5e-08.
