Let's divide 81887321 by 484
We want to divide 81887321 by 484.

Step 1:
If we divide 8 by 484, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 484

Advancing to step 2:
If we divide 81 by 484, we get 0 and a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Fetch the next digit (8) from the dividend, attach it to 81 and continue: 818 / 484

Going ahead to step 3:
484 can be fit into 818 1 times, resulting in a remainder of 334.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 334 after subtracting 484 from 818.
Append the next digit (8) from the dividend to 334 and continue with: 3348 / 484

On to step 4:
3348 divided by 484 is 6 with a remainder of 444.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
The remainder is 444 after subtracting 2904 from 3348.
Take the next digit (7) from the dividend and append it to 444, then repeat: 4447 / 484

Step 5:
If we divide 4447 by 484, we get 9 and a remainder of 91.
The next digit of our result is 9. 
Result so far: 169.0
Deduct 4356 from 4447 and we're left with 91.
Grab the next digit (3) from the dividend, add it to 91, then carry on: 913 / 484

Let's proceed to step 6:
484 can be fit into 913 1 times, resulting in a remainder of 429.
Use 1 as the next digit of our solution. 
Result so far: 1691.0
Subtracting 484 from 913 leaves us with 429.
Bring next digit (2) of the dividend behind the 429 and repeat the process: 4292 / 484

Moving on to step 7:
When dividing 4292 by 484, we get 8 with a remainder of 420.
Put 8 as the next digit of the answer. 
Result so far: 16918.0
The remainder is 420 after subtracting 3872 from 4292.
Include the next digit (1) from the dividend after 420, then repeat: 4201 / 484

Going ahead to step 8:
The number 484 fits into 4201 8 times, leaving a remainder of 329.
Use 8 as the next digit of our solution. 
Result so far: 169188.0
If we subtract 3872 from 4201, we get 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Moving on to step 9:
484 goes into 3290 6 times with a remainder of 386.
Record the quotient 6 as the next digit in the result. 
Result so far: 169188.6
The remainder is 386 after subtracting 2904 from 3290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Moving on to step 10:
3860 divided by 484 is 7 with a remainder of 472.
Record the quotient 7 as the next digit in the result. 
Result so far: 169188.67
Subtract 3388 from 3860 to get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Going ahead to step 11:
484 goes into 4720 9 times with a remainder of 364.
Use 9 as the next digit of our solution. 
Result so far: 169188.679
The remainder is 364 after subtracting 4356 from 4720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Moving on to step 12:
The number 484 fits into 3640 7 times, leaving a remainder of 252.
Record the quotient 7 as the next digit in the result. 
Result so far: 169188.6797
The remainder is 252 after subtracting 3388 from 3640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Step 13:
The number 484 fits into 2520 5 times, leaving a remainder of 100.
The next digit of our result is 5. 
Result so far: 169188.67975
If we subtract 2420 from 2520, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 14:
484 goes into 1000 2 times with a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 169188.679752
Subtract 968 from 1000 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 15:
If we divide 320 by 484, we get 0 and a remainder of 320.
Use 0 as the next digit of our solution. 
Result so far: 169188.679752
Deduct 0 from 320 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 16:
The number 484 fits into 3200 6 times, leaving a remainder of 296.
The next digit of our result is 6. 
Result so far: 169188.67975206
Deduct 2904 from 3200 and we're left with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

After the division, we end up with 169188.67975206 and a remainder of 2.96e-07.
