86731273 divided by 209 
Let's see how many times 209 fits into 86731273.

On to step 1:
209 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 209

Let's proceed to step 2:
209 goes into 86 0 times with a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Take the next digit (7) from the dividend and append it to 86, then repeat: 867 / 209

On to step 3:
209 can be fit into 867 4 times, resulting in a remainder of 31.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 836 from 867 leaves us with 31.
Take the next digit (3) from the dividend and append it to 31, then repeat: 313 / 209

On to step 4:
When dividing 313 by 209, we get 1 with a remainder of 104.
Write down 1 as next digit of the result. 
Result so far: 41.0
Deduct 209 from 313 and we're left with 104.
Grab the next digit (1) from the dividend, add it to 104, then carry on: 1041 / 209

Moving on to step 5:
If we divide 1041 by 209, we get 4 and a remainder of 205.
The next digit of our result is 4. 
Result so far: 414.0
Deduct 836 from 1041 and we're left with 205.
Fetch the next digit (2) from the dividend, attach it to 205 and continue: 2052 / 209

Step 6:
The number 209 fits into 2052 9 times, leaving a remainder of 171.
The number 9 becomes the next digit in our result. 
Result so far: 4149.0
The remainder is 171 after subtracting 1881 from 2052.
Bring next digit (7) of the dividend behind the 171 and repeat the process: 1717 / 209

Moving on to step 7:
209 goes into 1717 8 times with a remainder of 45.
Use 8 as the next digit of our solution. 
Result so far: 41498.0
Deduct 1672 from 1717 and we're left with 45.
Take the next digit (3) from the dividend and append it to 45, then repeat: 453 / 209

Going ahead to step 8:
209 goes into 453 2 times with a remainder of 35.
The number 2 becomes the next digit in our result. 
Result so far: 414982.0
Subtract 418 from 453 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 9:
The number 209 fits into 350 1 times, leaving a remainder of 141.
Put 1 as the next digit of the answer. 
Result so far: 414982.1
If we take 209 away from 350, we end up with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Let's proceed to step 10:
209 goes into 1410 6 times with a remainder of 156.
The next digit of our result is 6. 
Result so far: 414982.16
If we take 1254 away from 1410, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Step 11:
If we divide 1560 by 209, we get 7 and a remainder of 97.
The number 7 becomes the next digit in our result. 
Result so far: 414982.167
Subtracting 1463 from 1560 leaves us with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

On to step 12:
209 can be fit into 970 4 times, resulting in a remainder of 134.
Put 4 as the next digit of the answer. 
Result so far: 414982.1674
Subtracting 836 from 970 leaves us with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Let's proceed to step 13:
209 goes into 1340 6 times with a remainder of 86.
Use 6 as the next digit of our solution. 
Result so far: 414982.16746
The remainder is 86 after subtracting 1254 from 1340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 14:
If we divide 860 by 209, we get 4 and a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 414982.167464
Subtract 836 from 860 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 15:
209 can be fit into 240 1 times, resulting in a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 414982.1674641
Deduct 209 from 240 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 16:
The number 209 fits into 310 1 times, leaving a remainder of 101.
Write down 1 as next digit of the result. 
Result so far: 414982.16746411
Subtracting 209 from 310 leaves us with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

The final outcome is 414982.16746411, with a leftover of 1.01e-07.
