82915991 ÷ 42 
Our goal is to divide 82915991 by 42.

Step 1:
42 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 42

Advancing to step 2:
42 goes into 82 1 times with a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 42 from 82, we get 40.
Bring next digit (9) of the dividend behind the 40 and repeat the process: 409 / 42

Going ahead to step 3:
The number 42 fits into 409 9 times, leaving a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 19.0
If we take 378 away from 409, we end up with 31.
Append the next digit (1) from the dividend to 31 and continue with: 311 / 42

On to step 4:
When dividing 311 by 42, we get 7 with a remainder of 17.
The next digit of our result is 7. 
Result so far: 197.0
If we subtract 294 from 311, we get 17.
Fetch the next digit (5) from the dividend, attach it to 17 and continue: 175 / 42

Let's proceed to step 5:
When dividing 175 by 42, we get 4 with a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 1974.0
If we subtract 168 from 175, we get 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 42

On to step 6:
If we divide 79 by 42, we get 1 and a remainder of 37.
The next digit of our result is 1. 
Result so far: 19741.0
If we take 42 away from 79, we end up with 37.
Include the next digit (9) from the dividend after 37, then repeat: 379 / 42

Advancing to step 7:
If we divide 379 by 42, we get 9 and a remainder of 1.
The next digit of our result is 9. 
Result so far: 197419.0
Deduct 378 from 379 and we're left with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 42

Step 8:
If we divide 11 by 42, we get 0 and a remainder of 11.
The next digit of our result is 0. 
Result so far: 1974190.0
Subtract 0 from 11 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 9:
42 can be fit into 110 2 times, resulting in a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 1974190.2
Subtract 84 from 110 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 10:
42 goes into 260 6 times with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 1974190.26
Deduct 252 from 260 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 11:
The number 42 fits into 80 1 times, leaving a remainder of 38.
The next digit of our result is 1. 
Result so far: 1974190.261
Subtract 42 from 80 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.

Let's proceed to step 12:
42 goes into 380 9 times with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 1974190.2619
The remainder is 2 after subtracting 378 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 13:
42 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 1974190.2619
If we take 0 away from 20, 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.

Advancing to step 14:
If we divide 200 by 42, we get 4 and a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 1974190.261904
Deduct 168 from 200 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 15:
42 can be fit into 320 7 times, resulting in a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 1974190.2619047
Subtract 294 from 320 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 16:
42 goes into 260 6 times with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 1974190.26190476
If we subtract 252 from 260, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 1974190.26190476, and the remainder is 8e-09.
