Let's divide 170489 by 39
We want to divide 170489 by 39.

Let's proceed to step 1:
When dividing 1 by 39, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 39

Going ahead to step 2:
39 goes into 17 0 times with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Include the next digit (0) from the dividend after 17, then repeat: 170 / 39

On to step 3:
If we divide 170 by 39, we get 4 and a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 14 after subtracting 156 from 170.
Take the next digit (4) from the dividend and append it to 14, then repeat: 144 / 39

On to step 4:
39 can be fit into 144 3 times, resulting in a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 43.0
Deduct 117 from 144 and we're left with 27.
Bring next digit (8) of the dividend behind the 27 and repeat the process: 278 / 39

On to step 5:
If we divide 278 by 39, we get 7 and a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 437.0
Deduct 273 from 278 and we're left with 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 39

Going ahead to step 6:
59 divided by 39 is 1 with a remainder of 20.
The next digit of our result is 1. 
Result so far: 4371.0
Subtracting 39 from 59 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 7:
If we divide 200 by 39, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 4371.5
Deduct 195 from 200 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 8:
When dividing 50 by 39, we get 1 with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 4371.51
The remainder is 11 after subtracting 39 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 9:
110 divided by 39 is 2 with a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 4371.512
The remainder is 32 after subtracting 78 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 10:
When dividing 320 by 39, we get 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 4371.5128
Deduct 312 from 320 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
39 can be fit into 80 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 4371.51282
If we take 78 away from 80, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 12:
The number 39 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 4371.51282
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 13:
39 goes into 200 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 4371.5128205
The remainder is 5 after subtracting 195 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 14:
The number 39 fits into 50 1 times, leaving a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 4371.51282051
Deduct 39 from 50 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

After the division, we end up with 4371.51282051 and a remainder of 1.1e-08.
