We're dividing 86478460 by 253 
We're looking to find how many times 253 goes into 86478460.

Going ahead to step 1:
253 can be fit into 8 0 times, resulting in 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.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 253

Let's proceed to step 2:
The number 253 fits into 86 0 times, leaving a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Fetch the next digit (4) from the dividend, attach it to 86 and continue: 864 / 253

Step 3:
864 divided by 253 is 3 with a remainder of 105.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 759 from 864 leaves us with 105.
Bring next digit (7) of the dividend behind the 105 and repeat the process: 1057 / 253

Advancing to step 4:
If we divide 1057 by 253, we get 4 and a remainder of 45.
The next digit of our result is 4. 
Result so far: 34.0
The remainder is 45 after subtracting 1012 from 1057.
Take the next digit (8) from the dividend and append it to 45, then repeat: 458 / 253

Going ahead to step 5:
253 goes into 458 1 times with a remainder of 205.
The next digit of our result is 1. 
Result so far: 341.0
Subtract 253 from 458 to get 205.
Grab the next digit (4) from the dividend, add it to 205, then carry on: 2054 / 253

Going ahead to step 6:
2054 divided by 253 is 8 with a remainder of 30.
Record the quotient 8 as the next digit in the result. 
Result so far: 3418.0
If we subtract 2024 from 2054, we get 30.
Include the next digit (6) from the dividend after 30, then repeat: 306 / 253

Moving on to step 7:
If we divide 306 by 253, we get 1 and a remainder of 53.
Write down 1 as next digit of the result. 
Result so far: 34181.0
If we subtract 253 from 306, we get 53.
Take the next digit (0) from the dividend and append it to 53, then repeat: 530 / 253

Advancing to step 8:
253 can be fit into 530 2 times, resulting in a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 341812.0
Subtract 506 from 530 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.

Moving on to step 9:
The number 253 fits into 240 0 times, leaving a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 341812.0
Subtract 0 from 240 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 10:
253 can be fit into 2400 9 times, resulting in a remainder of 123.
Use 9 as the next digit of our solution. 
Result so far: 341812.09
If we take 2277 away from 2400, we end up with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Going ahead to step 11:
1230 divided by 253 is 4 with a remainder of 218.
The next digit of our result is 4. 
Result so far: 341812.094
Subtracting 1012 from 1230 leaves us with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

On to step 12:
2180 divided by 253 is 8 with a remainder of 156.
Write down 8 as next digit of the result. 
Result so far: 341812.0948
Subtracting 2024 from 2180 leaves us 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.

Going ahead to step 13:
When dividing 1560 by 253, we get 6 with a remainder of 42.
Use 6 as the next digit of our solution. 
Result so far: 341812.09486
Deduct 1518 from 1560 and we're left 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.

Moving on to step 14:
420 divided by 253 is 1 with a remainder of 167.
Record the quotient 1 as the next digit in the result. 
Result so far: 341812.094861
Deduct 253 from 420 and we're left with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Going ahead to step 15:
1670 divided by 253 is 6 with a remainder of 152.
Put 6 as the next digit of the answer. 
Result so far: 341812.0948616
Subtract 1518 from 1670 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 16:
If we divide 1520 by 253, we get 6 and a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 341812.09486166
Subtracting 1518 from 1520 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 341812.09486166, with a leftover of 2e-09.
