We look at the division of 16370642 by 203 
Our goal is to divide 16370642 by 203.

On to step 1:
When dividing 1 by 203, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 203

Moving on to step 2:
203 goes into 16 0 times with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Include the next digit (3) from the dividend after 16, then repeat: 163 / 203

Moving on to step 3:
The number 203 fits into 163 0 times, leaving a remainder of 163.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 163 leaves us with 163.
Take the next digit (7) from the dividend and append it to 163, then repeat: 1637 / 203

Going ahead to step 4:
203 goes into 1637 8 times with a remainder of 13.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 1624 from 1637 to get 13.
Fetch the next digit (0) from the dividend, attach it to 13 and continue: 130 / 203

Going ahead to step 5:
203 goes into 130 0 times with a remainder of 130.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
Subtract 0 from 130 to get 130.
Append the next digit (6) from the dividend to 130 and continue with: 1306 / 203

Let's proceed to step 6:
The number 203 fits into 1306 6 times, leaving a remainder of 88.
Write down 6 as next digit of the result. 
Result so far: 806.0
The remainder is 88 after subtracting 1218 from 1306.
Append the next digit (4) from the dividend to 88 and continue with: 884 / 203

Going ahead to step 7:
When dividing 884 by 203, we get 4 with a remainder of 72.
The next digit of our result is 4. 
Result so far: 8064.0
The remainder is 72 after subtracting 812 from 884.
Take the next digit (2) from the dividend and append it to 72, then repeat: 722 / 203

Going ahead to step 8:
When dividing 722 by 203, we get 3 with a remainder of 113.
Use 3 as the next digit of our solution. 
Result so far: 80643.0
Deduct 609 from 722 and we're left with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Going ahead to step 9:
1130 divided by 203 is 5 with a remainder of 115.
The next digit of our result is 5. 
Result so far: 80643.5
Subtract 1015 from 1130 to get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Moving on to step 10:
203 can be fit into 1150 5 times, resulting in a remainder of 135.
The next digit of our result is 5. 
Result so far: 80643.55
Deduct 1015 from 1150 and we're left with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

The quotient of the division is 80643.55, and the remainder is 0.135.
