We look at the division of 15594207 by 85 
Let's see how many times 85 fits into 15594207.

Going ahead to step 1:
The number 85 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 85

Advancing to step 2:
85 can be fit into 15 0 times, resulting in a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 85

Let's proceed to step 3:
The number 85 fits into 155 1 times, leaving a remainder of 70.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 85 from 155 to get 70.
Include the next digit (9) from the dividend after 70, then repeat: 709 / 85

On to step 4:
85 can be fit into 709 8 times, resulting in a remainder of 29.
The next digit of our result is 8. 
Result so far: 18.0
Deduct 680 from 709 and we're left with 29.
Bring next digit (4) of the dividend behind the 29 and repeat the process: 294 / 85

On to step 5:
The number 85 fits into 294 3 times, leaving a remainder of 39.
Write down 3 as next digit of the result. 
Result so far: 183.0
If we subtract 255 from 294, we get 39.
Append the next digit (2) from the dividend to 39 and continue with: 392 / 85

On to step 6:
392 divided by 85 is 4 with a remainder of 52.
Record the quotient 4 as the next digit in the result. 
Result so far: 1834.0
Subtract 340 from 392 to get 52.
Grab the next digit (0) from the dividend, add it to 52, then carry on: 520 / 85

Advancing to step 7:
85 goes into 520 6 times with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 18346.0
Subtracting 510 from 520 leaves us with 10.
Append the next digit (7) from the dividend to 10 and continue with: 107 / 85

Going ahead to step 8:
When dividing 107 by 85, we get 1 with a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 183461.0
The remainder is 22 after subtracting 85 from 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 9:
85 can be fit into 220 2 times, resulting in a remainder of 50.
The number 2 becomes the next digit in our result. 
Result so far: 183461.2
The remainder is 50 after subtracting 170 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
85 can be fit into 500 5 times, resulting in a remainder of 75.
The next digit of our result is 5. 
Result so far: 183461.25
Subtracting 425 from 500 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 11:
750 divided by 85 is 8 with a remainder of 70.
Use 8 as the next digit of our solution. 
Result so far: 183461.258
Subtracting 680 from 750 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 12:
If we divide 700 by 85, we get 8 and a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 183461.2588
The remainder is 20 after subtracting 680 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 183461.2588, with a leftover of 0.0002.
