86724665 ÷ 507 
We want to figure out the number of times 86724665 can be divided by 507.

Going ahead to step 1:
507 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 507

Going ahead to step 2:
86 divided by 507 is 0 with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Bring next digit (7) of the dividend behind the 86 and repeat the process: 867 / 507

Step 3:
507 can be fit into 867 1 times, resulting in a remainder of 360.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 507 from 867 and we're left with 360.
Append the next digit (2) from the dividend to 360 and continue with: 3602 / 507

Moving on to step 4:
507 can be fit into 3602 7 times, resulting in a remainder of 53.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtract 3549 from 3602 to get 53.
Append the next digit (4) from the dividend to 53 and continue with: 534 / 507

Advancing to step 5:
If we divide 534 by 507, we get 1 and a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 171.0
Subtracting 507 from 534 leaves us with 27.
Append the next digit (6) from the dividend to 27 and continue with: 276 / 507

Moving on to step 6:
The number 507 fits into 276 0 times, leaving a remainder of 276.
Record the quotient 0 as the next digit in the result. 
Result so far: 1710.0
Subtract 0 from 276 to get 276.
Bring next digit (6) of the dividend behind the 276 and repeat the process: 2766 / 507

Going ahead to step 7:
2766 divided by 507 is 5 with a remainder of 231.
Put 5 as the next digit of the answer. 
Result so far: 17105.0
If we take 2535 away from 2766, we end up with 231.
Append the next digit (5) from the dividend to 231 and continue with: 2315 / 507

Going ahead to step 8:
When dividing 2315 by 507, we get 4 with a remainder of 287.
Put 4 as the next digit of the answer. 
Result so far: 171054.0
Deduct 2028 from 2315 and we're left with 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Going ahead to step 9:
507 can be fit into 2870 5 times, resulting in a remainder of 335.
Record the quotient 5 as the next digit in the result. 
Result so far: 171054.5
The remainder is 335 after subtracting 2535 from 2870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Moving on to step 10:
The number 507 fits into 3350 6 times, leaving a remainder of 308.
Use 6 as the next digit of our solution. 
Result so far: 171054.56
The remainder is 308 after subtracting 3042 from 3350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Advancing to step 11:
507 can be fit into 3080 6 times, resulting in a remainder of 38.
The next digit of our result is 6. 
Result so far: 171054.566
Subtracting 3042 from 3080 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.

Our division results in 171054.566 with a remaining 0.0038.
