80646689 ÷ 562 
Our goal is to divide 80646689 by 562.

On to step 1:
When dividing 8 by 562, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 562

Advancing to step 2:
When dividing 80 by 562, we get 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Append the next digit (6) from the dividend to 80 and continue with: 806 / 562

Let's proceed to step 3:
If we divide 806 by 562, we get 1 and a remainder of 244.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 562 from 806, we get 244.
Include the next digit (4) from the dividend after 244, then repeat: 2444 / 562

On to step 4:
The number 562 fits into 2444 4 times, leaving a remainder of 196.
Use 4 as the next digit of our solution. 
Result so far: 14.0
The remainder is 196 after subtracting 2248 from 2444.
Fetch the next digit (6) from the dividend, attach it to 196 and continue: 1966 / 562

Let's proceed to step 5:
1966 divided by 562 is 3 with a remainder of 280.
Record the quotient 3 as the next digit in the result. 
Result so far: 143.0
If we subtract 1686 from 1966, we get 280.
Grab the next digit (6) from the dividend, add it to 280, then carry on: 2806 / 562

Let's proceed to step 6:
When dividing 2806 by 562, we get 4 with a remainder of 558.
Use 4 as the next digit of our solution. 
Result so far: 1434.0
Subtract 2248 from 2806 to get 558.
Fetch the next digit (8) from the dividend, attach it to 558 and continue: 5588 / 562

On to step 7:
5588 divided by 562 is 9 with a remainder of 530.
The number 9 becomes the next digit in our result. 
Result so far: 14349.0
Deduct 5058 from 5588 and we're left with 530.
Grab the next digit (9) from the dividend, add it to 530, then carry on: 5309 / 562

Moving on to step 8:
562 goes into 5309 9 times with a remainder of 251.
Record the quotient 9 as the next digit in the result. 
Result so far: 143499.0
Deduct 5058 from 5309 and we're left with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

On to step 9:
2510 divided by 562 is 4 with a remainder of 262.
Record the quotient 4 as the next digit in the result. 
Result so far: 143499.4
If we subtract 2248 from 2510, we get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Moving on to step 10:
If we divide 2620 by 562, we get 4 and a remainder of 372.
Record the quotient 4 as the next digit in the result. 
Result so far: 143499.44
Subtracting 2248 from 2620 leaves us with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

After the division, we end up with 143499.44 and a remainder of 0.372.
