We look at the division of 354585 by 87 
We want to divide 354585 by 87.

Advancing to step 1:
87 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 87

Advancing to step 2:
35 divided by 87 is 0 with a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Take the next digit (4) from the dividend and append it to 35, then repeat: 354 / 87

On to step 3:
When dividing 354 by 87, we get 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 348 from 354 leaves us with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 87

Moving on to step 4:
The number 87 fits into 65 0 times, leaving a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
Subtract 0 from 65 to get 65.
Bring next digit (8) of the dividend behind the 65 and repeat the process: 658 / 87

Step 5:
If we divide 658 by 87, we get 7 and a remainder of 49.
Record the quotient 7 as the next digit in the result. 
Result so far: 407.0
The remainder is 49 after subtracting 609 from 658.
Bring next digit (5) of the dividend behind the 49 and repeat the process: 495 / 87

Moving on to step 6:
495 divided by 87 is 5 with a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 4075.0
If we take 435 away from 495, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 7:
87 can be fit into 600 6 times, resulting in a remainder of 78.
Put 6 as the next digit of the answer. 
Result so far: 4075.6
Deduct 522 from 600 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 8:
87 can be fit into 780 8 times, resulting in a remainder of 84.
Record the quotient 8 as the next digit in the result. 
Result so far: 4075.68
Subtracting 696 from 780 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 9:
If we divide 840 by 87, we get 9 and a remainder of 57.
The next digit of our result is 9. 
Result so far: 4075.689
The remainder is 57 after subtracting 783 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 10:
87 goes into 570 6 times with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 4075.6896
Deduct 522 from 570 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 11:
When dividing 480 by 87, we get 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 4075.68965
Deduct 435 from 480 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 12:
The number 87 fits into 450 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 4075.689655
The remainder is 15 after subtracting 435 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Our division results in 4075.689655 with a remaining 1.5e-06.
