We're dividing 953503 by 40 
Our goal is to divide 953503 by 40.

Advancing to step 1:
9 divided by 40 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 40

Going ahead to step 2:
40 can be fit into 95 2 times, resulting in a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 80 from 95 and we're left with 15.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 40

On to step 3:
153 divided by 40 is 3 with a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 23.0
If we take 120 away from 153, we end up with 33.
Bring next digit (5) of the dividend behind the 33 and repeat the process: 335 / 40

Advancing to step 4:
40 goes into 335 8 times with a remainder of 15.
Record the quotient 8 as the next digit in the result. 
Result so far: 238.0
If we subtract 320 from 335, we get 15.
Grab the next digit (0) from the dividend, add it to 15, then carry on: 150 / 40

Going ahead to step 5:
When dividing 150 by 40, we get 3 with a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 2383.0
The remainder is 30 after subtracting 120 from 150.
Append the next digit (3) from the dividend to 30 and continue with: 303 / 40

On to step 6:
When dividing 303 by 40, we get 7 with a remainder of 23.
The next digit of our result is 7. 
Result so far: 23837.0
Subtract 280 from 303 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 7:
If we divide 230 by 40, we get 5 and a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 23837.5
The remainder is 30 after subtracting 200 from 230.
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 8:
40 can be fit into 300 7 times, resulting in a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 23837.57
Subtracting 280 from 300 leaves us 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.

Step 9:
When dividing 200 by 40, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 23837.575
Subtracting 200 from 200 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 23837.575
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 23837.575
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 23837.575 with a remainder of 0.0.
