Let's divide 620593 by 40
We want to figure out the number of times 620593 can be divided by 40.

Advancing to step 1:
40 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 40

Going ahead to step 2:
62 divided by 40 is 1 with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 40 from 62, we get 22.
Fetch the next digit (0) from the dividend, attach it to 22 and continue: 220 / 40

Let's proceed to step 3:
40 can be fit into 220 5 times, resulting in a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we subtract 200 from 220, we get 20.
Append the next digit (5) from the dividend to 20 and continue with: 205 / 40

Going ahead to step 4:
205 divided by 40 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 155.0
Deduct 200 from 205 and we're left with 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 40

Going ahead to step 5:
If we divide 59 by 40, we get 1 and a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 1551.0
Subtracting 40 from 59 leaves us with 19.
Grab the next digit (3) from the dividend, add it to 19, then carry on: 193 / 40

Step 6:
40 goes into 193 4 times with a remainder of 33.
Put 4 as the next digit of the answer. 
Result so far: 15514.0
Subtracting 160 from 193 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 7:
40 goes into 330 8 times with a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 15514.8
The remainder is 10 after subtracting 320 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
40 goes into 100 2 times with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 15514.82
Subtract 80 from 100 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.

Step 9:
40 goes into 200 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 15514.825
Subtract 200 from 200 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.

On to step 10:
40 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 15514.825
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.

On to step 11:
The number 40 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 15514.825
If we subtract 0 from 0, 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.

The final outcome is 15514.825, with a leftover of 0.0.
