We're dividing 81225176 by 507 
We want to divide 81225176 by 507.

Step 1:
When dividing 8 by 507, we get 0 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.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 507

Advancing to step 2:
507 can be fit into 81 0 times, resulting in a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Include the next digit (2) from the dividend after 81, then repeat: 812 / 507

Let's proceed to step 3:
812 divided by 507 is 1 with a remainder of 305.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 507 from 812, we get 305.
Take the next digit (2) from the dividend and append it to 305, then repeat: 3052 / 507

Moving on to step 4:
507 goes into 3052 6 times with a remainder of 10.
The next digit of our result is 6. 
Result so far: 16.0
The remainder is 10 after subtracting 3042 from 3052.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 507

Let's proceed to step 5:
105 divided by 507 is 0 with a remainder of 105.
Write down 0 as next digit of the result. 
Result so far: 160.0
Deduct 0 from 105 and we're left with 105.
Grab the next digit (1) from the dividend, add it to 105, then carry on: 1051 / 507

Advancing to step 6:
If we divide 1051 by 507, we get 2 and a remainder of 37.
Use 2 as the next digit of our solution. 
Result so far: 1602.0
If we take 1014 away from 1051, we end up with 37.
Fetch the next digit (7) from the dividend, attach it to 37 and continue: 377 / 507

Let's proceed to step 7:
377 divided by 507 is 0 with a remainder of 377.
Write down 0 as next digit of the result. 
Result so far: 16020.0
Subtract 0 from 377 to get 377.
Take the next digit (6) from the dividend and append it to 377, then repeat: 3776 / 507

Let's proceed to step 8:
507 goes into 3776 7 times with a remainder of 227.
Record the quotient 7 as the next digit in the result. 
Result so far: 160207.0
If we subtract 3549 from 3776, we get 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

On to step 9:
The number 507 fits into 2270 4 times, leaving a remainder of 242.
Record the quotient 4 as the next digit in the result. 
Result so far: 160207.4
If we subtract 2028 from 2270, we get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Advancing to step 10:
507 goes into 2420 4 times with a remainder of 392.
The next digit of our result is 4. 
Result so far: 160207.44
If we take 2028 away from 2420, we end up with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

The quotient of the division is 160207.44, and the remainder is 0.392.
