Let's divide 308451 by 81
We're looking to find how many times 81 goes into 308451.

Let's proceed to step 1:
3 divided by 81 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 81

Step 2:
81 goes into 30 0 times with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Include the next digit (8) from the dividend after 30, then repeat: 308 / 81

Advancing to step 3:
308 divided by 81 is 3 with a remainder of 65.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 243 from 308 and we're left with 65.
Grab the next digit (4) from the dividend, add it to 65, then carry on: 654 / 81

Going ahead to step 4:
If we divide 654 by 81, we get 8 and a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
Subtracting 648 from 654 leaves us with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 81

Going ahead to step 5:
If we divide 65 by 81, we get 0 and a remainder of 65.
Write down 0 as next digit of the result. 
Result so far: 380.0
If we subtract 0 from 65, we get 65.
Take the next digit (1) from the dividend and append it to 65, then repeat: 651 / 81

Moving on to step 6:
If we divide 651 by 81, we get 8 and a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 3808.0
If we take 648 away from 651, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
The number 81 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 3808.0
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
When dividing 300 by 81, we get 3 with a remainder of 57.
The number 3 becomes the next digit in our result. 
Result so far: 3808.03
Subtracting 243 from 300 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 9:
570 divided by 81 is 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 3808.037
Subtracting 567 from 570 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 10:
81 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 3808.037
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 11:
81 goes into 300 3 times with a remainder of 57.
The number 3 becomes the next digit in our result. 
Result so far: 3808.03703
Deduct 243 from 300 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 12:
81 can be fit into 570 7 times, resulting in a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 3808.037037
The remainder is 3 after subtracting 567 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 13:
The number 81 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 3808.037037
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 14:
81 can be fit into 300 3 times, resulting in a remainder of 57.
Record the quotient 3 as the next digit in the result. 
Result so far: 3808.03703703
If we subtract 243 from 300, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

After the division, we end up with 3808.03703703 and a remainder of 5.7e-08.
