Let's divide 81235389 by 806
We're looking to find how many times 806 goes into 81235389.

On to step 1:
806 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 806

Moving on to step 2:
The number 806 fits into 81 0 times, leaving a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Append the next digit (2) from the dividend to 81 and continue with: 812 / 806

Let's proceed to step 3:
When dividing 812 by 806, we get 1 with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 806 from 812 to get 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 806

Moving on to step 4:
806 can be fit into 63 0 times, resulting in a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 63, we get 63.
Include the next digit (5) from the dividend after 63, then repeat: 635 / 806

Let's proceed to step 5:
The number 806 fits into 635 0 times, leaving a remainder of 635.
Use 0 as the next digit of our solution. 
Result so far: 100.0
Subtracting 0 from 635 leaves us with 635.
Append the next digit (3) from the dividend to 635 and continue with: 6353 / 806

Moving on to step 6:
When dividing 6353 by 806, we get 7 with a remainder of 711.
Record the quotient 7 as the next digit in the result. 
Result so far: 1007.0
Subtracting 5642 from 6353 leaves us with 711.
Bring next digit (8) of the dividend behind the 711 and repeat the process: 7118 / 806

Let's proceed to step 7:
When dividing 7118 by 806, we get 8 with a remainder of 670.
Record the quotient 8 as the next digit in the result. 
Result so far: 10078.0
If we take 6448 away from 7118, we end up with 670.
Fetch the next digit (9) from the dividend, attach it to 670 and continue: 6709 / 806

Going ahead to step 8:
806 goes into 6709 8 times with a remainder of 261.
The number 8 becomes the next digit in our result. 
Result so far: 100788.0
Subtracting 6448 from 6709 leaves us with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Step 9:
2610 divided by 806 is 3 with a remainder of 192.
The next digit of our result is 3. 
Result so far: 100788.3
Subtract 2418 from 2610 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 10:
806 goes into 1920 2 times with a remainder of 308.
Put 2 as the next digit of the answer. 
Result so far: 100788.32
The remainder is 308 after subtracting 1612 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Going ahead to step 11:
If we divide 3080 by 806, we get 3 and a remainder of 662.
The number 3 becomes the next digit in our result. 
Result so far: 100788.323
If we take 2418 away from 3080, we end up with 662.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

Going ahead to step 12:
If we divide 6620 by 806, we get 8 and a remainder of 172.
The number 8 becomes the next digit in our result. 
Result so far: 100788.3238
Subtract 6448 from 6620 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Advancing to step 13:
806 goes into 1720 2 times with a remainder of 108.
Use 2 as the next digit of our solution. 
Result so far: 100788.32382
Subtracting 1612 from 1720 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 14:
The number 806 fits into 1080 1 times, leaving a remainder of 274.
Put 1 as the next digit of the answer. 
Result so far: 100788.323821
If we take 806 away from 1080, we end up with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Let's proceed to step 15:
The number 806 fits into 2740 3 times, leaving a remainder of 322.
Write down 3 as next digit of the result. 
Result so far: 100788.3238213
If we take 2418 away from 2740, we end up with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Moving on to step 16:
If we divide 3220 by 806, we get 3 and a remainder of 802.
Write down 3 as next digit of the result. 
Result so far: 100788.32382133
The remainder is 802 after subtracting 2418 from 3220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8020, and continue the process.

The final result is 100788.32382133 with a remainder of 8.02e-07.
