We divide 638610 by 81
Our goal is to divide 638610 by 81.

Moving on to step 1:
6 divided by 81 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 81

Step 2:
81 goes into 63 0 times with a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Fetch the next digit (8) from the dividend, attach it to 63 and continue: 638 / 81

Advancing to step 3:
81 can be fit into 638 7 times, resulting in a remainder of 71.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 567 from 638, we get 71.
Grab the next digit (6) from the dividend, add it to 71, then carry on: 716 / 81

Let's proceed to step 4:
The number 81 fits into 716 8 times, leaving a remainder of 68.
Use 8 as the next digit of our solution. 
Result so far: 78.0
The remainder is 68 after subtracting 648 from 716.
Grab the next digit (1) from the dividend, add it to 68, then carry on: 681 / 81

Let's proceed to step 5:
When dividing 681 by 81, we get 8 with a remainder of 33.
Use 8 as the next digit of our solution. 
Result so far: 788.0
The remainder is 33 after subtracting 648 from 681.
Take the next digit (0) from the dividend and append it to 33, then repeat: 330 / 81

Let's proceed to step 6:
81 goes into 330 4 times with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 7884.0
Subtracting 324 from 330 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
If we divide 60 by 81, we get 0 and a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 7884.0
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 8:
The number 81 fits into 600 7 times, leaving a remainder of 33.
The next digit of our result is 7. 
Result so far: 7884.07
The remainder is 33 after subtracting 567 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 9:
330 divided by 81 is 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 7884.074
The remainder is 6 after subtracting 324 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 10:
60 divided by 81 is 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 7884.074
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 11:
The number 81 fits into 600 7 times, leaving a remainder of 33.
Use 7 as the next digit of our solution. 
Result so far: 7884.07407
The remainder is 33 after subtracting 567 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 12:
81 can be fit into 330 4 times, resulting in a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 7884.074074
If we subtract 324 from 330, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 13:
The number 81 fits into 60 0 times, leaving a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 7884.074074
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 14:
81 can be fit into 600 7 times, resulting in a remainder of 33.
The next digit of our result is 7. 
Result so far: 7884.07407407
If we take 567 away from 600, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

The final outcome is 7884.07407407, with a leftover of 3.3e-08.
