We look at the division of 103245 by 35 
We want to figure out the number of times 103245 can be divided by 35.

On to step 1:
If we divide 1 by 35, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 35

On to step 2:
The number 35 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 35

Let's proceed to step 3:
When dividing 103 by 35, we get 2 with a remainder of 33.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 70 from 103 and we're left with 33.
Grab the next digit (2) from the dividend, add it to 33, then carry on: 332 / 35

Advancing to step 4:
When dividing 332 by 35, we get 9 with a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
If we take 315 away from 332, we end up with 17.
Grab the next digit (4) from the dividend, add it to 17, then carry on: 174 / 35

Moving on to step 5:
When dividing 174 by 35, we get 4 with a remainder of 34.
The next digit of our result is 4. 
Result so far: 294.0
Subtracting 140 from 174 leaves us with 34.
Append the next digit (5) from the dividend to 34 and continue with: 345 / 35

Going ahead to step 6:
The number 35 fits into 345 9 times, leaving a remainder of 30.
The next digit of our result is 9. 
Result so far: 2949.0
If we take 315 away from 345, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 7:
The number 35 fits into 300 8 times, leaving a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 2949.8
Deduct 280 from 300 and we're left 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.

Going ahead to step 8:
When dividing 200 by 35, we get 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 2949.85
Deduct 175 from 200 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 9:
When dividing 250 by 35, we get 7 with a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 2949.857
If we take 245 away from 250, we end up 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.

Step 10:
35 can be fit into 50 1 times, resulting in a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 2949.8571
If we take 35 away from 50, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 11:
When dividing 150 by 35, we get 4 with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 2949.85714
If we take 140 away from 150, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 12:
100 divided by 35 is 2 with a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 2949.857142
If we take 70 away from 100, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 13:
The number 35 fits into 300 8 times, leaving a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 2949.8571428
Subtract 280 from 300 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 14:
35 goes into 200 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 2949.85714285
If we subtract 175 from 200, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final outcome is 2949.85714285, with a leftover of 2.5e-08.
