Let's divide 78241122 by 486
Our goal is to divide 78241122 by 486.

On to step 1:
486 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 486

Advancing to step 2:
When dividing 78 by 486, we get 0 with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Bring next digit (2) of the dividend behind the 78 and repeat the process: 782 / 486

Advancing to step 3:
The number 486 fits into 782 1 times, leaving a remainder of 296.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 486 from 782, we get 296.
Include the next digit (4) from the dividend after 296, then repeat: 2964 / 486

Step 4:
The number 486 fits into 2964 6 times, leaving a remainder of 48.
The next digit of our result is 6. 
Result so far: 16.0
Subtract 2916 from 2964 to get 48.
Include the next digit (1) from the dividend after 48, then repeat: 481 / 486

On to step 5:
If we divide 481 by 486, we get 0 and a remainder of 481.
Record the quotient 0 as the next digit in the result. 
Result so far: 160.0
If we subtract 0 from 481, we get 481.
Grab the next digit (1) from the dividend, add it to 481, then carry on: 4811 / 486

Moving on to step 6:
The number 486 fits into 4811 9 times, leaving a remainder of 437.
Put 9 as the next digit of the answer. 
Result so far: 1609.0
Deduct 4374 from 4811 and we're left with 437.
Grab the next digit (2) from the dividend, add it to 437, then carry on: 4372 / 486

Step 7:
4372 divided by 486 is 8 with a remainder of 484.
Write down 8 as next digit of the result. 
Result so far: 16098.0
If we subtract 3888 from 4372, we get 484.
Take the next digit (2) from the dividend and append it to 484, then repeat: 4842 / 486

Advancing to step 8:
486 goes into 4842 9 times with a remainder of 468.
Use 9 as the next digit of our solution. 
Result so far: 160989.0
Subtract 4374 from 4842 to get 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Advancing to step 9:
When dividing 4680 by 486, we get 9 with a remainder of 306.
The number 9 becomes the next digit in our result. 
Result so far: 160989.9
Subtracting 4374 from 4680 leaves us with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Advancing to step 10:
If we divide 3060 by 486, we get 6 and a remainder of 144.
The next digit of our result is 6. 
Result so far: 160989.96
Subtract 2916 from 3060 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Moving on to step 11:
486 can be fit into 1440 2 times, resulting in a remainder of 468.
Put 2 as the next digit of the answer. 
Result so far: 160989.962
If we take 972 away from 1440, we end up with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Step 12:
When dividing 4680 by 486, we get 9 with a remainder of 306.
The next digit of our result is 9. 
Result so far: 160989.9629
If we take 4374 away from 4680, we end up with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Step 13:
When dividing 3060 by 486, we get 6 with a remainder of 144.
Write down 6 as next digit of the result. 
Result so far: 160989.96296
If we subtract 2916 from 3060, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 14:
486 can be fit into 1440 2 times, resulting in a remainder of 468.
Use 2 as the next digit of our solution. 
Result so far: 160989.962962
The remainder is 468 after subtracting 972 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Moving on to step 15:
486 goes into 4680 9 times with a remainder of 306.
The next digit of our result is 9. 
Result so far: 160989.9629629
Subtracting 4374 from 4680 leaves us with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Going ahead to step 16:
3060 divided by 486 is 6 with a remainder of 144.
Write down 6 as next digit of the result. 
Result so far: 160989.96296296
If we subtract 2916 from 3060, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

The quotient of the division is 160989.96296296, and the remainder is 1.44e-07.
