We look at the division of 80531921 by 388 
We want to divide 80531921 by 388.

On to step 1:
8 divided by 388 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 388

Step 2:
When dividing 80 by 388, we get 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Append the next digit (5) from the dividend to 80 and continue with: 805 / 388

On to step 3:
388 goes into 805 2 times with a remainder of 29.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 776 from 805 to get 29.
Grab the next digit (3) from the dividend, add it to 29, then carry on: 293 / 388

Let's proceed to step 4:
The number 388 fits into 293 0 times, leaving a remainder of 293.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
The remainder is 293 after subtracting 0 from 293.
Fetch the next digit (1) from the dividend, attach it to 293 and continue: 2931 / 388

Let's proceed to step 5:
The number 388 fits into 2931 7 times, leaving a remainder of 215.
The number 7 becomes the next digit in our result. 
Result so far: 207.0
Subtract 2716 from 2931 to get 215.
Grab the next digit (9) from the dividend, add it to 215, then carry on: 2159 / 388

Moving on to step 6:
388 can be fit into 2159 5 times, resulting in a remainder of 219.
Write down 5 as next digit of the result. 
Result so far: 2075.0
Deduct 1940 from 2159 and we're left with 219.
Include the next digit (2) from the dividend after 219, then repeat: 2192 / 388

Step 7:
2192 divided by 388 is 5 with a remainder of 252.
Record the quotient 5 as the next digit in the result. 
Result so far: 20755.0
Deduct 1940 from 2192 and we're left with 252.
Include the next digit (1) from the dividend after 252, then repeat: 2521 / 388

On to step 8:
388 goes into 2521 6 times with a remainder of 193.
Use 6 as the next digit of our solution. 
Result so far: 207556.0
Subtracting 2328 from 2521 leaves us with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Step 9:
The number 388 fits into 1930 4 times, leaving a remainder of 378.
The number 4 becomes the next digit in our result. 
Result so far: 207556.4
Subtracting 1552 from 1930 leaves us with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Moving on to step 10:
When dividing 3780 by 388, we get 9 with a remainder of 288.
Use 9 as the next digit of our solution. 
Result so far: 207556.49
Deduct 3492 from 3780 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Advancing to step 11:
If we divide 2880 by 388, we get 7 and a remainder of 164.
The number 7 becomes the next digit in our result. 
Result so far: 207556.497
If we take 2716 away from 2880, we end up with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Moving on to step 12:
388 can be fit into 1640 4 times, resulting in a remainder of 88.
Put 4 as the next digit of the answer. 
Result so far: 207556.4974
The remainder is 88 after subtracting 1552 from 1640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 13:
388 goes into 880 2 times with a remainder of 104.
The number 2 becomes the next digit in our result. 
Result so far: 207556.49742
Deduct 776 from 880 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 14:
388 goes into 1040 2 times with a remainder of 264.
Use 2 as the next digit of our solution. 
Result so far: 207556.497422
Subtracting 776 from 1040 leaves us with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

The final result is 207556.497422 with a remainder of 2.64e-05.
