We look at the division of 10430215 by 703 
We're looking to find how many times 703 goes into 10430215.

Going ahead to step 1:
When dividing 1 by 703, we get 0 with a remainder of 1.
Write down 0 as next digit of the 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 / 703

Let's proceed to step 2:
703 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 703

On to step 3:
If we divide 104 by 703, we get 0 and a remainder of 104.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 104, we get 104.
Include the next digit (3) from the dividend after 104, then repeat: 1043 / 703

On to step 4:
1043 divided by 703 is 1 with a remainder of 340.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 703 from 1043 to get 340.
Include the next digit (0) from the dividend after 340, then repeat: 3400 / 703

Going ahead to step 5:
The number 703 fits into 3400 4 times, leaving a remainder of 588.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we subtract 2812 from 3400, we get 588.
Grab the next digit (2) from the dividend, add it to 588, then carry on: 5882 / 703

Advancing to step 6:
703 goes into 5882 8 times with a remainder of 258.
The next digit of our result is 8. 
Result so far: 148.0
Subtracting 5624 from 5882 leaves us with 258.
Fetch the next digit (1) from the dividend, attach it to 258 and continue: 2581 / 703

Going ahead to step 7:
When dividing 2581 by 703, we get 3 with a remainder of 472.
The number 3 becomes the next digit in our result. 
Result so far: 1483.0
Subtract 2109 from 2581 to get 472.
Fetch the next digit (5) from the dividend, attach it to 472 and continue: 4725 / 703

Moving on to step 8:
When dividing 4725 by 703, we get 6 with a remainder of 507.
Record the quotient 6 as the next digit in the result. 
Result so far: 14836.0
Subtracting 4218 from 4725 leaves us with 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

Let's proceed to step 9:
If we divide 5070 by 703, we get 7 and a remainder of 149.
Put 7 as the next digit of the answer. 
Result so far: 14836.7
Deduct 4921 from 5070 and we're left with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Advancing to step 10:
If we divide 1490 by 703, we get 2 and a remainder of 84.
The number 2 becomes the next digit in our result. 
Result so far: 14836.72
Deduct 1406 from 1490 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 11:
703 goes into 840 1 times with a remainder of 137.
Use 1 as the next digit of our solution. 
Result so far: 14836.721
The remainder is 137 after subtracting 703 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Step 12:
The number 703 fits into 1370 1 times, leaving a remainder of 667.
Use 1 as the next digit of our solution. 
Result so far: 14836.7211
If we take 703 away from 1370, we end up with 667.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6670, and continue the process.

After the division, we end up with 14836.7211 and a remainder of 0.00667.
