Let's divide 80030755 by 81
Let's see how many times 81 fits into 80030755.

Let's proceed to step 1:
81 goes into 8 0 times with 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.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 81

Step 2:
81 goes into 80 0 times with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Append the next digit (0) from the dividend to 80 and continue with: 800 / 81

Going ahead to step 3:
When dividing 800 by 81, we get 9 with a remainder of 71.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 729 from 800, we get 71.
Bring next digit (3) of the dividend behind the 71 and repeat the process: 713 / 81

Going ahead to step 4:
81 can be fit into 713 8 times, resulting in a remainder of 65.
Write down 8 as next digit of the result. 
Result so far: 98.0
Subtract 648 from 713 to get 65.
Include the next digit (0) from the dividend after 65, then repeat: 650 / 81

Advancing to step 5:
The number 81 fits into 650 8 times, leaving a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 988.0
Deduct 648 from 650 and we're left with 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 81

Let's proceed to step 6:
81 goes into 27 0 times with a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 9880.0
Deduct 0 from 27 and we're left with 27.
Bring next digit (5) of the dividend behind the 27 and repeat the process: 275 / 81

Advancing to step 7:
275 divided by 81 is 3 with a remainder of 32.
Put 3 as the next digit of the answer. 
Result so far: 98803.0
Subtracting 243 from 275 leaves us with 32.
Grab the next digit (5) from the dividend, add it to 32, then carry on: 325 / 81

Step 8:
81 goes into 325 4 times with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 988034.0
Subtract 324 from 325 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
10 divided by 81 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 988034.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
81 can be fit into 100 1 times, resulting in a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 988034.01
The remainder is 19 after subtracting 81 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 11:
The number 81 fits into 190 2 times, leaving a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 988034.012
If we subtract 162 from 190, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 12:
280 divided by 81 is 3 with a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 988034.0123
Deduct 243 from 280 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 13:
When dividing 370 by 81, we get 4 with a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 988034.01234
If we subtract 324 from 370, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 14:
81 can be fit into 460 5 times, resulting in a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 988034.012345
If we subtract 405 from 460, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 15:
550 divided by 81 is 6 with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 988034.0123456
If we take 486 away from 550, we end up 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.

Going ahead to step 16:
If we divide 640 by 81, we get 7 and a remainder of 73.
The number 7 becomes the next digit in our result. 
Result so far: 988034.01234567
Deduct 567 from 640 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Our division results in 988034.01234567 with a remaining 7.3e-08.
