Let's divide 221629 by 40
We want to figure out the number of times 221629 can be divided by 40.

Advancing to step 1:
If we divide 2 by 40, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 40

On to step 2:
The number 40 fits into 22 0 times, leaving a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 22 to get 22.
Take the next digit (1) from the dividend and append it to 22, then repeat: 221 / 40

Let's proceed to step 3:
221 divided by 40 is 5 with a remainder of 21.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 200 from 221 to get 21.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 40

Going ahead to step 4:
40 goes into 216 5 times with a remainder of 16.
The number 5 becomes the next digit in our result. 
Result so far: 55.0
Deduct 200 from 216 and we're left with 16.
Grab the next digit (2) from the dividend, add it to 16, then carry on: 162 / 40

On to step 5:
When dividing 162 by 40, we get 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 554.0
If we subtract 160 from 162, we get 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 40

Going ahead to step 6:
When dividing 29 by 40, we get 0 with a remainder of 29.
Write down 0 as next digit of the result. 
Result so far: 5540.0
Deduct 0 from 29 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 7:
The number 40 fits into 290 7 times, leaving a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 5540.7
The remainder is 10 after subtracting 280 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
40 goes into 100 2 times with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 5540.72
If we take 80 away from 100, we end up 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:
When dividing 200 by 40, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 5540.725
The remainder is 0 after subtracting 200 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
The number 40 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 5540.725
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.

Going ahead 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: 5540.725
The remainder is 0 after subtracting 0 from 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 5540.725 with a remainder of 0.0.
