We look at the division of 159997 by 39 
We want to figure out the number of times 159997 can be divided by 39.

Step 1:
39 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 39

Going ahead to step 2:
39 can be fit into 15 0 times, resulting in a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 39

Moving on to step 3:
39 can be fit into 159 4 times, resulting in a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 156 from 159 and we're left with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 39

Moving on to step 4:
When dividing 39 by 39, we get 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 41.0
Subtracting 39 from 39 leaves us with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 39

Step 5:
39 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 410.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 39

Going ahead to step 6:
39 goes into 97 2 times with a remainder of 19.
Write down 2 as next digit of the result. 
Result so far: 4102.0
Subtract 78 from 97 to 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.

Let's proceed to step 7:
39 can be fit into 190 4 times, resulting in a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 4102.4
The remainder is 34 after subtracting 156 from 190.
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 8:
39 goes into 340 8 times with a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 4102.48
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.

Advancing to step 9:
The number 39 fits into 280 7 times, leaving a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 4102.487
If we take 273 away from 280, we end up with 7.
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 10:
When dividing 70 by 39, we get 1 with a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 4102.4871
If we subtract 39 from 70, we get 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 11:
When dividing 310 by 39, we get 7 with a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 4102.48717
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.

Going ahead to step 12:
39 goes into 370 9 times with a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 4102.487179
Subtract 351 from 370 to 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 13:
If we divide 190 by 39, we get 4 and a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 4102.4871794
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.

Moving on to step 14:
340 divided by 39 is 8 with a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 4102.48717948
The remainder is 28 after subtracting 312 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The quotient of the division is 4102.48717948, and the remainder is 2.8e-08.
