We're dividing 308507 by 87 
We want to figure out the number of times 308507 can be divided by 87.

Going ahead to step 1:
If we divide 3 by 87, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 87

Going ahead to step 2:
If we divide 30 by 87, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Grab the next digit (8) from the dividend, add it to 30, then carry on: 308 / 87

On to step 3:
87 goes into 308 3 times with a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 261 from 308 leaves us with 47.
Include the next digit (5) from the dividend after 47, then repeat: 475 / 87

Moving on to step 4:
475 divided by 87 is 5 with a remainder of 40.
The next digit of our result is 5. 
Result so far: 35.0
If we subtract 435 from 475, we get 40.
Bring next digit (0) of the dividend behind the 40 and repeat the process: 400 / 87

Step 5:
400 divided by 87 is 4 with a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 354.0
If we take 348 away from 400, we end up with 52.
Grab the next digit (7) from the dividend, add it to 52, then carry on: 527 / 87

Going ahead to step 6:
527 divided by 87 is 6 with a remainder of 5.
The next digit of our result is 6. 
Result so far: 3546.0
Subtracting 522 from 527 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
If we divide 50 by 87, we get 0 and a remainder of 50.
The next digit of our result is 0. 
Result so far: 3546.0
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
The number 87 fits into 500 5 times, leaving a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 3546.05
If we subtract 435 from 500, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 9:
When dividing 650 by 87, we get 7 with a remainder of 41.
Record the quotient 7 as the next digit in the result. 
Result so far: 3546.057
Deduct 609 from 650 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 10:
When dividing 410 by 87, we get 4 with a remainder of 62.
Use 4 as the next digit of our solution. 
Result so far: 3546.0574
Subtracting 348 from 410 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 11:
The number 87 fits into 620 7 times, leaving a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 3546.05747
Subtract 609 from 620 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 12:
If we divide 110 by 87, we get 1 and a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 3546.057471
The remainder is 23 after subtracting 87 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 13:
87 can be fit into 230 2 times, resulting in a remainder of 56.
Use 2 as the next digit of our solution. 
Result so far: 3546.0574712
If we subtract 174 from 230, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 14:
The number 87 fits into 560 6 times, leaving a remainder of 38.
Put 6 as the next digit of the answer. 
Result so far: 3546.05747126
Subtracting 522 from 560 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

After the division, we end up with 3546.05747126 and a remainder of 3.8e-08.
