We look at the division of 86304887 by 210 
We're looking to find how many times 210 goes into 86304887.

Step 1:
When dividing 8 by 210, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 210

Going ahead to step 2:
When dividing 86 by 210, we get 0 with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Bring next digit (3) of the dividend behind the 86 and repeat the process: 863 / 210

Going ahead to step 3:
The number 210 fits into 863 4 times, leaving a remainder of 23.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 840 from 863, we get 23.
Fetch the next digit (0) from the dividend, attach it to 23 and continue: 230 / 210

Moving on to step 4:
If we divide 230 by 210, we get 1 and a remainder of 20.
The next digit of our result is 1. 
Result so far: 41.0
If we take 210 away from 230, we end up with 20.
Take the next digit (4) from the dividend and append it to 20, then repeat: 204 / 210

Step 5:
210 goes into 204 0 times with a remainder of 204.
Write down 0 as next digit of the result. 
Result so far: 410.0
The remainder is 204 after subtracting 0 from 204.
Take the next digit (8) from the dividend and append it to 204, then repeat: 2048 / 210

Moving on to step 6:
2048 divided by 210 is 9 with a remainder of 158.
Put 9 as the next digit of the answer. 
Result so far: 4109.0
Subtracting 1890 from 2048 leaves us with 158.
Fetch the next digit (8) from the dividend, attach it to 158 and continue: 1588 / 210

Going ahead to step 7:
The number 210 fits into 1588 7 times, leaving a remainder of 118.
The next digit of our result is 7. 
Result so far: 41097.0
If we take 1470 away from 1588, we end up with 118.
Take the next digit (7) from the dividend and append it to 118, then repeat: 1187 / 210

On to step 8:
If we divide 1187 by 210, we get 5 and a remainder of 137.
Record the quotient 5 as the next digit in the result. 
Result so far: 410975.0
Subtract 1050 from 1187 to get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Moving on to step 9:
210 goes into 1370 6 times with a remainder of 110.
Use 6 as the next digit of our solution. 
Result so far: 410975.6
If we subtract 1260 from 1370, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 10:
210 can be fit into 1100 5 times, resulting in a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 410975.65
Subtract 1050 from 1100 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 11:
When dividing 500 by 210, we get 2 with a remainder of 80.
Write down 2 as next digit of the result. 
Result so far: 410975.652
Deduct 420 from 500 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 12:
When dividing 800 by 210, we get 3 with a remainder of 170.
Put 3 as the next digit of the answer. 
Result so far: 410975.6523
Subtracting 630 from 800 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 13:
1700 divided by 210 is 8 with a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 410975.65238
If we subtract 1680 from 1700, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 14:
200 divided by 210 is 0 with a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 410975.65238
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 15:
When dividing 2000 by 210, we get 9 with a remainder of 110.
Put 9 as the next digit of the answer. 
Result so far: 410975.6523809
Subtracting 1890 from 2000 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 16:
If we divide 1100 by 210, we get 5 and a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 410975.65238095
The remainder is 50 after subtracting 1050 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 410975.65238095 with a remaining 5e-08.
