We're dividing 80477390 by 525 
We want to divide 80477390 by 525.

Let's proceed to step 1:
When dividing 8 by 525, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 525

Moving on to step 2:
80 divided by 525 is 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Fetch the next digit (4) from the dividend, attach it to 80 and continue: 804 / 525

Step 3:
If we divide 804 by 525, we get 1 and a remainder of 279.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 525 from 804 to get 279.
Include the next digit (7) from the dividend after 279, then repeat: 2797 / 525

Going ahead to step 4:
2797 divided by 525 is 5 with a remainder of 172.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 2625 from 2797 to get 172.
Take the next digit (7) from the dividend and append it to 172, then repeat: 1727 / 525

On to step 5:
When dividing 1727 by 525, we get 3 with a remainder of 152.
Use 3 as the next digit of our solution. 
Result so far: 153.0
Deduct 1575 from 1727 and we're left with 152.
Bring next digit (3) of the dividend behind the 152 and repeat the process: 1523 / 525

Moving on to step 6:
When dividing 1523 by 525, we get 2 with a remainder of 473.
The number 2 becomes the next digit in our result. 
Result so far: 1532.0
Subtracting 1050 from 1523 leaves us with 473.
Take the next digit (9) from the dividend and append it to 473, then repeat: 4739 / 525

Moving on to step 7:
When dividing 4739 by 525, we get 9 with a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 15329.0
Subtracting 4725 from 4739 leaves us with 14.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 525

Let's proceed to step 8:
140 divided by 525 is 0 with a remainder of 140.
The next digit of our result is 0. 
Result so far: 153290.0
Subtract 0 from 140 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 9:
When dividing 1400 by 525, we get 2 with a remainder of 350.
The number 2 becomes the next digit in our result. 
Result so far: 153290.2
Subtracting 1050 from 1400 leaves us with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Advancing to step 10:
525 goes into 3500 6 times with a remainder of 350.
The number 6 becomes the next digit in our result. 
Result so far: 153290.26
If we subtract 3150 from 3500, we get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Moving on to step 11:
3500 divided by 525 is 6 with a remainder of 350.
Record the quotient 6 as the next digit in the result. 
Result so far: 153290.266
If we take 3150 away from 3500, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

The final outcome is 153290.266, with a leftover of 0.035.
