21929106 ÷ 40 
We're looking to find how many times 40 goes into 21929106.

Advancing to step 1:
If we divide 2 by 40, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 40

Going ahead to step 2:
When dividing 21 by 40, we get 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Include the next digit (9) from the dividend after 21, then repeat: 219 / 40

Let's proceed to step 3:
If we divide 219 by 40, we get 5 and a remainder of 19.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 200 away from 219, we end up with 19.
Append the next digit (2) from the dividend to 19 and continue with: 192 / 40

Step 4:
40 goes into 192 4 times with a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 54.0
Deduct 160 from 192 and we're left with 32.
Take the next digit (9) from the dividend and append it to 32, then repeat: 329 / 40

Let's proceed to step 5:
40 goes into 329 8 times with a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 548.0
The remainder is 9 after subtracting 320 from 329.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 40

On to step 6:
91 divided by 40 is 2 with a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 5482.0
If we take 80 away from 91, we end up with 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 40

Step 7:
The number 40 fits into 110 2 times, leaving a remainder of 30.
The next digit of our result is 2. 
Result so far: 54822.0
If we subtract 80 from 110, we get 30.
Append the next digit (6) from the dividend to 30 and continue with: 306 / 40

Advancing to step 8:
40 can be fit into 306 7 times, resulting in a remainder of 26.
Record the quotient 7 as the next digit in the result. 
Result so far: 548227.0
Deduct 280 from 306 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 9:
When dividing 260 by 40, we get 6 with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 548227.6
Deduct 240 from 260 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.

Going ahead to step 10:
If we divide 200 by 40, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 548227.65
If we take 200 away from 200, 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.

On to step 11:
0 divided by 40 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 548227.65
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.

Advancing to step 12:
If we divide 0 by 40, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 548227.65
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 outcome is 548227.65, with a leftover of 0.0.
