86138111 ÷ 524 
Let's see how many times 524 fits into 86138111.

Going ahead to step 1:
8 divided by 524 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 524

On to step 2:
When dividing 86 by 524, we get 0 with a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Grab the next digit (1) from the dividend, add it to 86, then carry on: 861 / 524

Going ahead to step 3:
861 divided by 524 is 1 with a remainder of 337.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 524 from 861 leaves us with 337.
Take the next digit (3) from the dividend and append it to 337, then repeat: 3373 / 524

Step 4:
3373 divided by 524 is 6 with a remainder of 229.
Write down 6 as next digit of the result. 
Result so far: 16.0
Deduct 3144 from 3373 and we're left with 229.
Include the next digit (8) from the dividend after 229, then repeat: 2298 / 524

Step 5:
524 goes into 2298 4 times with a remainder of 202.
The next digit of our result is 4. 
Result so far: 164.0
If we take 2096 away from 2298, we end up with 202.
Append the next digit (1) from the dividend to 202 and continue with: 2021 / 524

Going ahead to step 6:
524 goes into 2021 3 times with a remainder of 449.
The next digit of our result is 3. 
Result so far: 1643.0
Deduct 1572 from 2021 and we're left with 449.
Grab the next digit (1) from the dividend, add it to 449, then carry on: 4491 / 524

Let's proceed to step 7:
4491 divided by 524 is 8 with a remainder of 299.
Record the quotient 8 as the next digit in the result. 
Result so far: 16438.0
Deduct 4192 from 4491 and we're left with 299.
Bring next digit (1) of the dividend behind the 299 and repeat the process: 2991 / 524

Going ahead to step 8:
The number 524 fits into 2991 5 times, leaving a remainder of 371.
The number 5 becomes the next digit in our result. 
Result so far: 164385.0
If we take 2620 away from 2991, we end up with 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Let's proceed to step 9:
If we divide 3710 by 524, we get 7 and a remainder of 42.
The number 7 becomes the next digit in our result. 
Result so far: 164385.7
Subtracting 3668 from 3710 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 10:
When dividing 420 by 524, we get 0 with a remainder of 420.
Write down 0 as next digit of the result. 
Result so far: 164385.7
Deduct 0 from 420 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 11:
524 goes into 4200 8 times with a remainder of 8.
The next digit of our result is 8. 
Result so far: 164385.708
The remainder is 8 after subtracting 4192 from 4200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 12:
The number 524 fits into 80 0 times, leaving a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 164385.708
Subtracting 0 from 80 leaves us 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.

Let's proceed to step 13:
The number 524 fits into 800 1 times, leaving a remainder of 276.
The number 1 becomes the next digit in our result. 
Result so far: 164385.70801
Subtract 524 from 800 to get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Let's proceed to step 14:
2760 divided by 524 is 5 with a remainder of 140.
Put 5 as the next digit of the answer. 
Result so far: 164385.708015
The remainder is 140 after subtracting 2620 from 2760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 15:
524 goes into 1400 2 times with a remainder of 352.
Use 2 as the next digit of our solution. 
Result so far: 164385.7080152
The remainder is 352 after subtracting 1048 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Going ahead to step 16:
524 can be fit into 3520 6 times, resulting in a remainder of 376.
Put 6 as the next digit of the answer. 
Result so far: 164385.70801526
The remainder is 376 after subtracting 3144 from 3520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

In conclusion, the division gives 164385.70801526 with a balance of 3.76e-07.
