Let's divide 80991876 by 557
We want to divide 80991876 by 557.

On to step 1:
8 divided by 557 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 557

Let's proceed to step 2:
When dividing 80 by 557, we get 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Bring next digit (9) of the dividend behind the 80 and repeat the process: 809 / 557

On to step 3:
When dividing 809 by 557, we get 1 with a remainder of 252.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 557 from 809 to get 252.
Grab the next digit (9) from the dividend, add it to 252, then carry on: 2529 / 557

Moving on to step 4:
557 can be fit into 2529 4 times, resulting in a remainder of 301.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
The remainder is 301 after subtracting 2228 from 2529.
Grab the next digit (1) from the dividend, add it to 301, then carry on: 3011 / 557

Going ahead to step 5:
The number 557 fits into 3011 5 times, leaving a remainder of 226.
Use 5 as the next digit of our solution. 
Result so far: 145.0
Subtract 2785 from 3011 to get 226.
Append the next digit (8) from the dividend to 226 and continue with: 2268 / 557

Moving on to step 6:
When dividing 2268 by 557, we get 4 with a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 1454.0
Deduct 2228 from 2268 and we're left with 40.
Include the next digit (7) from the dividend after 40, then repeat: 407 / 557

Going ahead to step 7:
If we divide 407 by 557, we get 0 and a remainder of 407.
Record the quotient 0 as the next digit in the result. 
Result so far: 14540.0
If we take 0 away from 407, we end up with 407.
Include the next digit (6) from the dividend after 407, then repeat: 4076 / 557

On to step 8:
557 can be fit into 4076 7 times, resulting in a remainder of 177.
Write down 7 as next digit of the result. 
Result so far: 145407.0
Deduct 3899 from 4076 and we're left with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Let's proceed to step 9:
When dividing 1770 by 557, we get 3 with a remainder of 99.
Use 3 as the next digit of our solution. 
Result so far: 145407.3
The remainder is 99 after subtracting 1671 from 1770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Going ahead to step 10:
990 divided by 557 is 1 with a remainder of 433.
Record the quotient 1 as the next digit in the result. 
Result so far: 145407.31
Subtracting 557 from 990 leaves us with 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Advancing to step 11:
When dividing 4330 by 557, we get 7 with a remainder of 431.
Write down 7 as next digit of the result. 
Result so far: 145407.317
Subtracting 3899 from 4330 leaves us with 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

Moving on to step 12:
The number 557 fits into 4310 7 times, leaving a remainder of 411.
The next digit of our result is 7. 
Result so far: 145407.3177
Subtract 3899 from 4310 to get 411.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

Our division results in 145407.3177 with a remaining 0.00411.
