Let's divide 12859560 by 557
Our goal is to divide 12859560 by 557.

Going ahead to step 1:
If we divide 1 by 557, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 557

Moving on to step 2:
557 goes into 12 0 times with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 557

On to step 3:
128 divided by 557 is 0 with a remainder of 128.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 128, we get 128.
Append the next digit (5) from the dividend to 128 and continue with: 1285 / 557

Let's proceed to step 4:
The number 557 fits into 1285 2 times, leaving a remainder of 171.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 1114 away from 1285, we end up with 171.
Append the next digit (9) from the dividend to 171 and continue with: 1719 / 557

On to step 5:
557 can be fit into 1719 3 times, resulting in a remainder of 48.
Put 3 as the next digit of the answer. 
Result so far: 23.0
If we take 1671 away from 1719, we end up with 48.
Bring next digit (5) of the dividend behind the 48 and repeat the process: 485 / 557

Advancing to step 6:
When dividing 485 by 557, we get 0 with a remainder of 485.
Use 0 as the next digit of our solution. 
Result so far: 230.0
If we take 0 away from 485, we end up with 485.
Take the next digit (6) from the dividend and append it to 485, then repeat: 4856 / 557

Going ahead to step 7:
When dividing 4856 by 557, we get 8 with a remainder of 400.
The next digit of our result is 8. 
Result so far: 2308.0
Subtracting 4456 from 4856 leaves us with 400.
Include the next digit (0) from the dividend after 400, then repeat: 4000 / 557

Advancing to step 8:
If we divide 4000 by 557, we get 7 and a remainder of 101.
The next digit of our result is 7. 
Result so far: 23087.0
Subtracting 3899 from 4000 leaves us with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Let's proceed to step 9:
When dividing 1010 by 557, we get 1 with a remainder of 453.
Use 1 as the next digit of our solution. 
Result so far: 23087.1
If we take 557 away from 1010, we end up with 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

Advancing to step 10:
557 goes into 4530 8 times with a remainder of 74.
The number 8 becomes the next digit in our result. 
Result so far: 23087.18
Deduct 4456 from 4530 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 11:
The number 557 fits into 740 1 times, leaving a remainder of 183.
The next digit of our result is 1. 
Result so far: 23087.181
The remainder is 183 after subtracting 557 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Let's proceed to step 12:
The number 557 fits into 1830 3 times, leaving a remainder of 159.
Use 3 as the next digit of our solution. 
Result so far: 23087.1813
If we subtract 1671 from 1830, we get 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Advancing to step 13:
The number 557 fits into 1590 2 times, leaving a remainder of 476.
The number 2 becomes the next digit in our result. 
Result so far: 23087.18132
If we take 1114 away from 1590, we end up with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Step 14:
When dividing 4760 by 557, we get 8 with a remainder of 304.
The number 8 becomes the next digit in our result. 
Result so far: 23087.181328
If we take 4456 away from 4760, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Advancing to step 15:
If we divide 3040 by 557, we get 5 and a remainder of 255.
Put 5 as the next digit of the answer. 
Result so far: 23087.1813285
Deduct 2785 from 3040 and we're left with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Let's proceed to step 16:
The number 557 fits into 2550 4 times, leaving a remainder of 322.
The next digit of our result is 4. 
Result so far: 23087.18132854
Subtracting 2228 from 2550 leaves us with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

The quotient of the division is 23087.18132854, and the remainder is 3.22e-07.
