80912722 ÷ 42 
We want to figure out the number of times 80912722 can be divided by 42.

On to step 1:
When dividing 8 by 42, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 42

Let's proceed to step 2:
42 can be fit into 80 1 times, resulting in a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 38 after subtracting 42 from 80.
Bring next digit (9) of the dividend behind the 38 and repeat the process: 389 / 42

Advancing to step 3:
42 can be fit into 389 9 times, resulting in a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Deduct 378 from 389 and we're left with 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 42

Going ahead to step 4:
111 divided by 42 is 2 with a remainder of 27.
Put 2 as the next digit of the answer. 
Result so far: 192.0
Deduct 84 from 111 and we're left with 27.
Grab the next digit (2) from the dividend, add it to 27, then carry on: 272 / 42

Going ahead to step 5:
When dividing 272 by 42, we get 6 with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 1926.0
The remainder is 20 after subtracting 252 from 272.
Take the next digit (7) from the dividend and append it to 20, then repeat: 207 / 42

On to step 6:
If we divide 207 by 42, we get 4 and a remainder of 39.
Put 4 as the next digit of the answer. 
Result so far: 19264.0
The remainder is 39 after subtracting 168 from 207.
Fetch the next digit (2) from the dividend, attach it to 39 and continue: 392 / 42

Advancing to step 7:
392 divided by 42 is 9 with a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 192649.0
If we subtract 378 from 392, we get 14.
Fetch the next digit (2) from the dividend, attach it to 14 and continue: 142 / 42

Let's proceed to step 8:
42 goes into 142 3 times with a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 1926493.0
Subtract 126 from 142 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 9:
The number 42 fits into 160 3 times, leaving a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 1926493.3
Subtracting 126 from 160 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 10:
340 divided by 42 is 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 1926493.38
Subtract 336 from 340 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 11:
The number 42 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 1926493.38
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
42 can be fit into 400 9 times, resulting in a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 1926493.3809
Deduct 378 from 400 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 13:
42 can be fit into 220 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 1926493.38095
The remainder is 10 after subtracting 210 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
42 goes into 100 2 times with a remainder of 16.
The next digit of our result is 2. 
Result so far: 1926493.380952
If we take 84 away from 100, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 15:
If we divide 160 by 42, we get 3 and a remainder of 34.
The next digit of our result is 3. 
Result so far: 1926493.3809523
Subtracting 126 from 160 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 16:
If we divide 340 by 42, we get 8 and a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 1926493.38095238
If we subtract 336 from 340, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 1926493.38095238, with a leftover of 4e-09.
