We look at the division of 170103 by 39 
We want to divide 170103 by 39.

Advancing to step 1:
1 divided by 39 is 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.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 39

Step 2:
39 goes into 17 0 times with a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 39

Let's proceed to step 3:
170 divided by 39 is 4 with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 156 from 170 and we're left with 14.
Take the next digit (1) from the dividend and append it to 14, then repeat: 141 / 39

Advancing to step 4:
The number 39 fits into 141 3 times, leaving a remainder of 24.
The next digit of our result is 3. 
Result so far: 43.0
The remainder is 24 after subtracting 117 from 141.
Include the next digit (0) from the dividend after 24, then repeat: 240 / 39

Going ahead to step 5:
When dividing 240 by 39, we get 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 436.0
The remainder is 6 after subtracting 234 from 240.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 39

Going ahead to step 6:
39 goes into 63 1 times with a remainder of 24.
Use 1 as the next digit of our solution. 
Result so far: 4361.0
If we subtract 39 from 63, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 7:
39 goes into 240 6 times with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 4361.6
Deduct 234 from 240 and we're left 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.

On to step 8:
If we divide 60 by 39, we get 1 and a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 4361.61
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.

Step 9:
39 goes into 210 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 4361.615
Subtract 195 from 210 to 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.

On to step 10:
39 can be fit into 150 3 times, resulting in a remainder of 33.
The next digit of our result is 3. 
Result so far: 4361.6153
If we subtract 117 from 150, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 11:
The number 39 fits into 330 8 times, leaving a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 4361.61538
Deduct 312 from 330 and we're left 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.

Advancing to step 12:
180 divided by 39 is 4 with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 4361.615384
The remainder is 24 after subtracting 156 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 13:
39 can be fit into 240 6 times, resulting in a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 4361.6153846
Subtracting 234 from 240 leaves us 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.

Step 14:
60 divided by 39 is 1 with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 4361.61538461
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.

The quotient of the division is 4361.61538461, and the remainder is 2.1e-08.
