We look at the division of 85510203 by 559 
We want to divide 85510203 by 559.

On to step 1:
559 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 559

On to step 2:
If we divide 85 by 559, we get 0 and a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 85 leaves us with 85.
Append the next digit (5) from the dividend to 85 and continue with: 855 / 559

Step 3:
The number 559 fits into 855 1 times, leaving a remainder of 296.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 296 after subtracting 559 from 855.
Fetch the next digit (1) from the dividend, attach it to 296 and continue: 2961 / 559

Step 4:
When dividing 2961 by 559, we get 5 with a remainder of 166.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Deduct 2795 from 2961 and we're left with 166.
Grab the next digit (0) from the dividend, add it to 166, then carry on: 1660 / 559

Let's proceed to step 5:
If we divide 1660 by 559, we get 2 and a remainder of 542.
Use 2 as the next digit of our solution. 
Result so far: 152.0
If we subtract 1118 from 1660, we get 542.
Grab the next digit (2) from the dividend, add it to 542, then carry on: 5422 / 559

Advancing to step 6:
559 can be fit into 5422 9 times, resulting in a remainder of 391.
Record the quotient 9 as the next digit in the result. 
Result so far: 1529.0
The remainder is 391 after subtracting 5031 from 5422.
Take the next digit (0) from the dividend and append it to 391, then repeat: 3910 / 559

Moving on to step 7:
If we divide 3910 by 559, we get 6 and a remainder of 556.
The next digit of our result is 6. 
Result so far: 15296.0
If we subtract 3354 from 3910, we get 556.
Append the next digit (3) from the dividend to 556 and continue with: 5563 / 559

On to step 8:
The number 559 fits into 5563 9 times, leaving a remainder of 532.
Use 9 as the next digit of our solution. 
Result so far: 152969.0
Subtract 5031 from 5563 to get 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Going ahead to step 9:
559 can be fit into 5320 9 times, resulting in a remainder of 289.
The next digit of our result is 9. 
Result so far: 152969.9
If we subtract 5031 from 5320, we get 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Step 10:
2890 divided by 559 is 5 with a remainder of 95.
Use 5 as the next digit of our solution. 
Result so far: 152969.95
The remainder is 95 after subtracting 2795 from 2890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Advancing to step 11:
The number 559 fits into 950 1 times, leaving a remainder of 391.
Put 1 as the next digit of the answer. 
Result so far: 152969.951
If we take 559 away from 950, we end up with 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Step 12:
If we divide 3910 by 559, we get 6 and a remainder of 556.
Write down 6 as next digit of the result. 
Result so far: 152969.9516
The remainder is 556 after subtracting 3354 from 3910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

On to step 13:
When dividing 5560 by 559, we get 9 with a remainder of 529.
The next digit of our result is 9. 
Result so far: 152969.95169
The remainder is 529 after subtracting 5031 from 5560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5290, and continue the process.

Step 14:
5290 divided by 559 is 9 with a remainder of 259.
Put 9 as the next digit of the answer. 
Result so far: 152969.951699
If we take 5031 away from 5290, we end up with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

The final result is 152969.951699 with a remainder of 2.59e-05.
