61978638 ÷ 82 
Our goal is to divide 61978638 by 82.

Going ahead to step 1:
If we divide 6 by 82, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 82

On to step 2:
If we divide 61 by 82, we get 0 and a remainder of 61.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 61 and we're left with 61.
Grab the next digit (9) from the dividend, add it to 61, then carry on: 619 / 82

Let's proceed to step 3:
82 can be fit into 619 7 times, resulting in a remainder of 45.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 574 away from 619, we end up with 45.
Append the next digit (7) from the dividend to 45 and continue with: 457 / 82

Moving on to step 4:
The number 82 fits into 457 5 times, leaving a remainder of 47.
Put 5 as the next digit of the answer. 
Result so far: 75.0
Subtracting 410 from 457 leaves us with 47.
Take the next digit (8) from the dividend and append it to 47, then repeat: 478 / 82

Step 5:
The number 82 fits into 478 5 times, leaving a remainder of 68.
Put 5 as the next digit of the answer. 
Result so far: 755.0
If we take 410 away from 478, we end up with 68.
Append the next digit (6) from the dividend to 68 and continue with: 686 / 82

Let's proceed to step 6:
The number 82 fits into 686 8 times, leaving a remainder of 30.
The number 8 becomes the next digit in our result. 
Result so far: 7558.0
Subtracting 656 from 686 leaves us with 30.
Take the next digit (3) from the dividend and append it to 30, then repeat: 303 / 82

Moving on to step 7:
If we divide 303 by 82, we get 3 and a remainder of 57.
Record the quotient 3 as the next digit in the result. 
Result so far: 75583.0
Subtracting 246 from 303 leaves us with 57.
Bring next digit (8) of the dividend behind the 57 and repeat the process: 578 / 82

Moving on to step 8:
82 goes into 578 7 times with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 755837.0
Subtract 574 from 578 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.

Going ahead to step 9:
The number 82 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 755837.0
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
82 goes into 400 4 times with a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 755837.04
The remainder is 72 after subtracting 328 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 11:
When dividing 720 by 82, we get 8 with a remainder of 64.
The next digit of our result is 8. 
Result so far: 755837.048
Deduct 656 from 720 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 12:
82 can be fit into 640 7 times, resulting in a remainder of 66.
Use 7 as the next digit of our solution. 
Result so far: 755837.0487
If we take 574 away from 640, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 13:
If we divide 660 by 82, we get 8 and a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 755837.04878
If we subtract 656 from 660, 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.

Let's proceed to step 14:
82 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 755837.04878
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 15:
400 divided by 82 is 4 with a remainder of 72.
The next digit of our result is 4. 
Result so far: 755837.0487804
Deduct 328 from 400 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 16:
720 divided by 82 is 8 with a remainder of 64.
Record the quotient 8 as the next digit in the result. 
Result so far: 755837.04878048
If we subtract 656 from 720, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 755837.04878048 with a remainder of 6.4e-08.
