41742020 ÷ 81 
We're looking to find how many times 81 goes into 41742020.

On to step 1:
81 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 81

Advancing to step 2:
41 divided by 81 is 0 with a remainder of 41.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 41 to get 41.
Take the next digit (7) from the dividend and append it to 41, then repeat: 417 / 81

Moving on to step 3:
81 can be fit into 417 5 times, resulting in a remainder of 12.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 405 from 417 to get 12.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 81

Step 4:
81 goes into 124 1 times with a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 51.0
If we subtract 81 from 124, we get 43.
Take the next digit (2) from the dividend and append it to 43, then repeat: 432 / 81

Let's proceed to step 5:
When dividing 432 by 81, we get 5 with a remainder of 27.
The number 5 becomes the next digit in our result. 
Result so far: 515.0
Subtract 405 from 432 to get 27.
Take the next digit (0) from the dividend and append it to 27, then repeat: 270 / 81

Moving on to step 6:
The number 81 fits into 270 3 times, leaving a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 5153.0
If we take 243 away from 270, we end up with 27.
Bring next digit (2) of the dividend behind the 27 and repeat the process: 272 / 81

Advancing to step 7:
When dividing 272 by 81, we get 3 with a remainder of 29.
The next digit of our result is 3. 
Result so far: 51533.0
The remainder is 29 after subtracting 243 from 272.
Take the next digit (0) from the dividend and append it to 29, then repeat: 290 / 81

Moving on to step 8:
81 goes into 290 3 times with a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 515333.0
The remainder is 47 after subtracting 243 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 9:
If we divide 470 by 81, we get 5 and a remainder of 65.
The next digit of our result is 5. 
Result so far: 515333.5
Subtracting 405 from 470 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 10:
81 can be fit into 650 8 times, resulting in a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 515333.58
Subtracting 648 from 650 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 11:
81 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 515333.58
Subtract 0 from 20 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.

On to step 12:
The number 81 fits into 200 2 times, leaving a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 515333.5802
Subtract 162 from 200 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 13:
If we divide 380 by 81, we get 4 and a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 515333.58024
If we subtract 324 from 380, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 14:
81 goes into 560 6 times with a remainder of 74.
The next digit of our result is 6. 
Result so far: 515333.580246
Deduct 486 from 560 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 15:
740 divided by 81 is 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 515333.5802469
Deduct 729 from 740 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 16:
The number 81 fits into 110 1 times, leaving a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 515333.58024691
If we subtract 81 from 110, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final result is 515333.58024691 with a remainder of 2.9e-08.
