80917521 divided by 41 
We want to figure out the number of times 80917521 can be divided by 41.

On to step 1:
When dividing 8 by 41, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 41

Let's proceed to step 2:
When dividing 80 by 41, we get 1 with a remainder of 39.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 41 from 80 leaves us with 39.
Grab the next digit (9) from the dividend, add it to 39, then carry on: 399 / 41

Going ahead to step 3:
When dividing 399 by 41, we get 9 with a remainder of 30.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtracting 369 from 399 leaves us with 30.
Take the next digit (1) from the dividend and append it to 30, then repeat: 301 / 41

Let's proceed to step 4:
The number 41 fits into 301 7 times, leaving a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 197.0
Subtract 287 from 301 to get 14.
Grab the next digit (7) from the dividend, add it to 14, then carry on: 147 / 41

Moving on to step 5:
The number 41 fits into 147 3 times, leaving a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 1973.0
Subtracting 123 from 147 leaves us with 24.
Bring next digit (5) of the dividend behind the 24 and repeat the process: 245 / 41

Moving on to step 6:
41 can be fit into 245 5 times, resulting in a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 19735.0
If we take 205 away from 245, we end up with 40.
Take the next digit (2) from the dividend and append it to 40, then repeat: 402 / 41

Going ahead to step 7:
If we divide 402 by 41, we get 9 and a remainder of 33.
Put 9 as the next digit of the answer. 
Result so far: 197359.0
Subtract 369 from 402 to get 33.
Bring next digit (1) of the dividend behind the 33 and repeat the process: 331 / 41

Moving on to step 8:
If we divide 331 by 41, we get 8 and a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 1973598.0
Subtracting 328 from 331 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
When dividing 30 by 41, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 1973598.0
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
300 divided by 41 is 7 with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 1973598.07
If we subtract 287 from 300, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 11:
41 can be fit into 130 3 times, resulting in a remainder of 7.
The next digit of our result is 3. 
Result so far: 1973598.073
If we take 123 away from 130, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 12:
41 can be fit into 70 1 times, resulting in a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 1973598.0731
The remainder is 29 after subtracting 41 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 13:
The number 41 fits into 290 7 times, leaving a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 1973598.07317
If we take 287 away from 290, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 14:
The number 41 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 1973598.07317
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 15:
41 goes into 300 7 times with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 1973598.0731707
The remainder is 13 after subtracting 287 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 16:
The number 41 fits into 130 3 times, leaving a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 1973598.07317073
Deduct 123 from 130 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

In conclusion, the division gives 1973598.07317073 with a balance of 7e-09.
