We look at the division of 629103 by 40 
We want to figure out the number of times 629103 can be divided by 40.

Advancing to step 1:
6 divided by 40 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 40

Going ahead to step 2:
The number 40 fits into 62 1 times, leaving a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 40 from 62 leaves us with 22.
Grab the next digit (9) from the dividend, add it to 22, then carry on: 229 / 40

On to step 3:
40 goes into 229 5 times with a remainder of 29.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we subtract 200 from 229, we get 29.
Fetch the next digit (1) from the dividend, attach it to 29 and continue: 291 / 40

Step 4:
The number 40 fits into 291 7 times, leaving a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 157.0
If we subtract 280 from 291, we get 11.
Include the next digit (0) from the dividend after 11, then repeat: 110 / 40

Advancing to step 5:
40 goes into 110 2 times with a remainder of 30.
The next digit of our result is 2. 
Result so far: 1572.0
Deduct 80 from 110 and we're left with 30.
Include the next digit (3) from the dividend after 30, then repeat: 303 / 40

Advancing to step 6:
The number 40 fits into 303 7 times, leaving a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 15727.0
The remainder is 23 after subtracting 280 from 303.
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:
230 divided by 40 is 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 15727.5
If we take 200 away from 230, 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 8:
40 goes into 300 7 times with a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 15727.57
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.

On to step 9:
40 goes into 200 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 15727.575
If we subtract 200 from 200, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
40 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 15727.575
Subtract 0 from 0 to get 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:
40 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 15727.575
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 outcome is 15727.575, with a leftover of 0.0.
