Advancing to step 4:
If we divide 583 by 636, we get 0 and a remainder of 583.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 583, we get 583.
Take the next digit (8) from the dividend and append it to 583, then repeat: 5838 / 636

Going ahead to step 5:
636 can be fit into 5838 9 times, resulting in a remainder of 114.
The number 9 becomes the next digit in our result. 
Result so far: 109.0
Subtracting 5724 from 5838 leaves us with 114.
Grab the next digit (3) from the dividend, add it to 114, then carry on: 1143 / 636

Going ahead to step 6:
The number 636 fits into 1143 1 times, leaving a remainder of 507.
The next digit of our result is 1. 
Result so far: 1091.0
Subtract 636 from 1143 to get 507.
Fetch the next digit (1) from the dividend, attach it to 507 and continue: 5071 / 636

On to step 7:
636 can be fit into 5071 7 times, resulting in a remainder of 619.
The next digit of our result is 7. 
Result so far: 10917.0
Subtract 4452 from 5071 to get 619.
Include the next digit (1) from the dividend after 619, then repeat: 6191 / 636

Step 8:
If we divide 6191 by 636, we get 9 and a remainder of 467.
Use 9 as the next digit of our solution. 
Result so far: 109179.0
Deduct 5724 from 6191 and we're left with 467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

Moving on to step 9:
The number 636 fits into 4670 7 times, leaving a remainder of 218.
The number 7 becomes the next digit in our result. 
Result so far: 109179.7
Subtract 4452 from 4670 to get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

On to step 10:
When dividing 2180 by 636, we get 3 with a remainder of 272.
Put 3 as the next digit of the answer. 
Result so far: 109179.73
Subtract 1908 from 2180 to get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Let's proceed to step 11:
636 goes into 2720 4 times with a remainder of 176.
Use 4 as the next digit of our solution. 
Result so far: 109179.734
The remainder is 176 after subtracting 2544 from 2720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 12:
636 can be fit into 1760 2 times, resulting in a remainder of 488.
The next digit of our result is 2. 
Result so far: 109179.7342
Deduct 1272 from 1760 and we're left with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Let's proceed to step 13:
The number 636 fits into 4880 7 times, leaving a remainder of 428.
The number 7 becomes the next digit in our result. 
Result so far: 109179.73427
Subtracting 4452 from 4880 leaves us with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Let's proceed to step 14:
636 can be fit into 4280 6 times, resulting in a remainder of 464.
Put 6 as the next digit of the answer. 
Result so far: 109179.734276
Deduct 3816 from 4280 and we're left with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Going ahead to step 15:
636 can be fit into 4640 7 times, resulting in a remainder of 188.
The number 7 becomes the next digit in our result. 
Result so far: 109179.7342767
Deduct 4452 from 4640 and we're left with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Advancing to step 16:
636 goes into 1880 2 times with a remainder of 608.
Write down 2 as next digit of the result. 
Result so far: 109179.73427672
The remainder is 608 after subtracting 1272 from 1880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

In conclusion, the division gives 109179.73427672 with a balance of 6.08e-07.
