We're dividing 86242144 by 253 
We want to figure out the number of times 86242144 can be divided by 253.

Moving on to step 1:
If we divide 8 by 253, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 253

On to step 2:
253 can be fit into 86 0 times, resulting in a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Include the next digit (2) from the dividend after 86, then repeat: 862 / 253

Let's proceed to step 3:
The number 253 fits into 862 3 times, leaving a remainder of 103.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 759 from 862 leaves us with 103.
Include the next digit (4) from the dividend after 103, then repeat: 1034 / 253

Let's proceed to step 4:
The number 253 fits into 1034 4 times, leaving a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
Deduct 1012 from 1034 and we're left with 22.
Include the next digit (2) from the dividend after 22, then repeat: 222 / 253

Moving on to step 5:
If we divide 222 by 253, we get 0 and a remainder of 222.
The next digit of our result is 0. 
Result so far: 340.0
Subtract 0 from 222 to get 222.
Bring next digit (1) of the dividend behind the 222 and repeat the process: 2221 / 253

Going ahead to step 6:
253 goes into 2221 8 times with a remainder of 197.
Write down 8 as next digit of the result. 
Result so far: 3408.0
Subtract 2024 from 2221 to get 197.
Include the next digit (4) from the dividend after 197, then repeat: 1974 / 253

On to step 7:
When dividing 1974 by 253, we get 7 with a remainder of 203.
The number 7 becomes the next digit in our result. 
Result so far: 34087.0
If we subtract 1771 from 1974, we get 203.
Include the next digit (4) from the dividend after 203, then repeat: 2034 / 253

Advancing to step 8:
2034 divided by 253 is 8 with a remainder of 10.
The next digit of our result is 8. 
Result so far: 340878.0
Subtracting 2024 from 2034 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
When dividing 100 by 253, we get 0 with a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 340878.0
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 10:
The number 253 fits into 1000 3 times, leaving a remainder of 241.
The number 3 becomes the next digit in our result. 
Result so far: 340878.03
If we take 759 away from 1000, we end up with 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Step 11:
The number 253 fits into 2410 9 times, leaving a remainder of 133.
Put 9 as the next digit of the answer. 
Result so far: 340878.039
Deduct 2277 from 2410 and we're left with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Moving on to step 12:
253 can be fit into 1330 5 times, resulting in a remainder of 65.
The next digit of our result is 5. 
Result so far: 340878.0395
If we take 1265 away from 1330, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 13:
If we divide 650 by 253, we get 2 and a remainder of 144.
Put 2 as the next digit of the answer. 
Result so far: 340878.03952
Subtract 506 from 650 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 14:
If we divide 1440 by 253, we get 5 and a remainder of 175.
Write down 5 as next digit of the result. 
Result so far: 340878.039525
Subtracting 1265 from 1440 leaves us with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Let's proceed to step 15:
The number 253 fits into 1750 6 times, leaving a remainder of 232.
Record the quotient 6 as the next digit in the result. 
Result so far: 340878.0395256
Subtracting 1518 from 1750 leaves us with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Step 16:
2320 divided by 253 is 9 with a remainder of 43.
Put 9 as the next digit of the answer. 
Result so far: 340878.03952569
If we take 2277 away from 2320, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

The quotient of the division is 340878.03952569, and the remainder is 4.3e-08.
