We look at the division of 86730253 by 485 
We want to divide 86730253 by 485.

Step 1:
The number 485 fits into 8 0 times, leaving 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.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 485

Going ahead to step 2:
485 can be fit into 86 0 times, resulting in a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Append the next digit (7) from the dividend to 86 and continue with: 867 / 485

Moving on to step 3:
485 can be fit into 867 1 times, resulting in a remainder of 382.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 485 away from 867, we end up with 382.
Fetch the next digit (3) from the dividend, attach it to 382 and continue: 3823 / 485

Step 4:
3823 divided by 485 is 7 with a remainder of 428.
The next digit of our result is 7. 
Result so far: 17.0
The remainder is 428 after subtracting 3395 from 3823.
Take the next digit (0) from the dividend and append it to 428, then repeat: 4280 / 485

Moving on to step 5:
485 can be fit into 4280 8 times, resulting in a remainder of 400.
Write down 8 as next digit of the result. 
Result so far: 178.0
Subtract 3880 from 4280 to get 400.
Take the next digit (2) from the dividend and append it to 400, then repeat: 4002 / 485

On to step 6:
If we divide 4002 by 485, we get 8 and a remainder of 122.
Write down 8 as next digit of the result. 
Result so far: 1788.0
Subtract 3880 from 4002 to get 122.
Bring next digit (5) of the dividend behind the 122 and repeat the process: 1225 / 485

Let's proceed to step 7:
485 can be fit into 1225 2 times, resulting in a remainder of 255.
Use 2 as the next digit of our solution. 
Result so far: 17882.0
If we subtract 970 from 1225, we get 255.
Bring next digit (3) of the dividend behind the 255 and repeat the process: 2553 / 485

Step 8:
485 goes into 2553 5 times with a remainder of 128.
The number 5 becomes the next digit in our result. 
Result so far: 178825.0
Deduct 2425 from 2553 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 9:
When dividing 1280 by 485, we get 2 with a remainder of 310.
The next digit of our result is 2. 
Result so far: 178825.2
The remainder is 310 after subtracting 970 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 10:
3100 divided by 485 is 6 with a remainder of 190.
The next digit of our result is 6. 
Result so far: 178825.26
If we subtract 2910 from 3100, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 11:
1900 divided by 485 is 3 with a remainder of 445.
Write down 3 as next digit of the result. 
Result so far: 178825.263
The remainder is 445 after subtracting 1455 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Advancing to step 12:
If we divide 4450 by 485, we get 9 and a remainder of 85.
Put 9 as the next digit of the answer. 
Result so far: 178825.2639
Subtract 4365 from 4450 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 13:
485 can be fit into 850 1 times, resulting in a remainder of 365.
Write down 1 as next digit of the result. 
Result so far: 178825.26391
If we subtract 485 from 850, we get 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Going ahead to step 14:
485 goes into 3650 7 times with a remainder of 255.
The number 7 becomes the next digit in our result. 
Result so far: 178825.263917
Subtracting 3395 from 3650 leaves us with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Let's proceed to step 15:
485 goes into 2550 5 times with a remainder of 125.
The number 5 becomes the next digit in our result. 
Result so far: 178825.2639175
Subtracting 2425 from 2550 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Step 16:
When dividing 1250 by 485, we get 2 with a remainder of 280.
Record the quotient 2 as the next digit in the result. 
Result so far: 178825.26391752
The remainder is 280 after subtracting 970 from 1250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

In conclusion, the division gives 178825.26391752 with a balance of 2.8e-07.
