We look at the division of 173049 by 39 
We want to figure out the number of times 173049 can be divided by 39.

On to step 1:
The number 39 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 39

Let's proceed to step 2:
39 can be fit into 17 0 times, resulting in a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 39

Let's proceed to step 3:
The number 39 fits into 173 4 times, leaving a remainder of 17.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 156 from 173, we get 17.
Include the next digit (0) from the dividend after 17, then repeat: 170 / 39

Advancing to step 4:
The number 39 fits into 170 4 times, leaving a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 44.0
Deduct 156 from 170 and we're left with 14.
Take the next digit (4) from the dividend and append it to 14, then repeat: 144 / 39

Advancing to step 5:
39 can be fit into 144 3 times, resulting in a remainder of 27.
The next digit of our result is 3. 
Result so far: 443.0
The remainder is 27 after subtracting 117 from 144.
Include the next digit (9) from the dividend after 27, then repeat: 279 / 39

On to step 6:
When dividing 279 by 39, we get 7 with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 4437.0
If we subtract 273 from 279, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
39 goes into 60 1 times with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 4437.1
If we take 39 away from 60, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 8:
210 divided by 39 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 4437.15
If we subtract 195 from 210, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 9:
150 divided by 39 is 3 with a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 4437.153
Subtracting 117 from 150 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 10:
If we divide 330 by 39, we get 8 and a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 4437.1538
If we take 312 away from 330, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 11:
180 divided by 39 is 4 with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 4437.15384
Subtracting 156 from 180 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 12:
If we divide 240 by 39, we get 6 and a remainder of 6.
The next digit of our result is 6. 
Result so far: 4437.153846
If we take 234 away from 240, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 13:
39 can be fit into 60 1 times, resulting in a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 4437.1538461
Subtracting 39 from 60 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 14:
39 can be fit into 210 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 4437.15384615
The remainder is 15 after subtracting 195 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final outcome is 4437.15384615, with a leftover of 1.5e-08.
