We're dividing 81220454 by 835 
We're looking to find how many times 835 goes into 81220454.

On to step 1:
835 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 835

On to step 2:
When dividing 81 by 835, we get 0 with 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.
Fetch the next digit (2) from the dividend, attach it to 81 and continue: 812 / 835

Let's proceed to step 3:
If we divide 812 by 835, we get 0 and a remainder of 812.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 812 and we're left with 812.
Append the next digit (2) from the dividend to 812 and continue with: 8122 / 835

Moving on to step 4:
The number 835 fits into 8122 9 times, leaving a remainder of 607.
The next digit of our result is 9. 
Result so far: 9.0
If we take 7515 away from 8122, we end up with 607.
Take the next digit (0) from the dividend and append it to 607, then repeat: 6070 / 835

Advancing to step 5:
835 goes into 6070 7 times with a remainder of 225.
Write down 7 as next digit of the result. 
Result so far: 97.0
The remainder is 225 after subtracting 5845 from 6070.
Include the next digit (4) from the dividend after 225, then repeat: 2254 / 835

Going ahead to step 6:
When dividing 2254 by 835, we get 2 with a remainder of 584.
Record the quotient 2 as the next digit in the result. 
Result so far: 972.0
The remainder is 584 after subtracting 1670 from 2254.
Include the next digit (5) from the dividend after 584, then repeat: 5845 / 835

Let's proceed to step 7:
When dividing 5845 by 835, we get 7 with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 9727.0
If we take 5845 away from 5845, we end up with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 835

Step 8:
When dividing 4 by 835, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 97270.0
Deduct 0 from 4 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
40 divided by 835 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 97270.0
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
If we divide 400 by 835, we get 0 and a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 97270.0
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final result is 97270.0 with a remainder of 0.4.
