85390131 ÷ 873 
Let's see how many times 873 fits into 85390131.

Let's proceed to step 1:
When dividing 8 by 873, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 873

Advancing to step 2:
85 divided by 873 is 0 with a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Bring next digit (3) of the dividend behind the 85 and repeat the process: 853 / 873

On to step 3:
873 goes into 853 0 times with a remainder of 853.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 853, we end up with 853.
Take the next digit (9) from the dividend and append it to 853, then repeat: 8539 / 873

Step 4:
873 can be fit into 8539 9 times, resulting in a remainder of 682.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 7857 from 8539 leaves us with 682.
Fetch the next digit (0) from the dividend, attach it to 682 and continue: 6820 / 873

Advancing to step 5:
The number 873 fits into 6820 7 times, leaving a remainder of 709.
Put 7 as the next digit of the answer. 
Result so far: 97.0
If we subtract 6111 from 6820, we get 709.
Include the next digit (1) from the dividend after 709, then repeat: 7091 / 873

Going ahead to step 6:
When dividing 7091 by 873, we get 8 with a remainder of 107.
Use 8 as the next digit of our solution. 
Result so far: 978.0
If we take 6984 away from 7091, we end up with 107.
Take the next digit (3) from the dividend and append it to 107, then repeat: 1073 / 873

On to step 7:
The number 873 fits into 1073 1 times, leaving a remainder of 200.
The number 1 becomes the next digit in our result. 
Result so far: 9781.0
If we take 873 away from 1073, we end up with 200.
Append the next digit (1) from the dividend to 200 and continue with: 2001 / 873

On to step 8:
When dividing 2001 by 873, we get 2 with a remainder of 255.
Use 2 as the next digit of our solution. 
Result so far: 97812.0
If we take 1746 away from 2001, we end up 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 9:
If we divide 2550 by 873, we get 2 and a remainder of 804.
Use 2 as the next digit of our solution. 
Result so far: 97812.2
If we subtract 1746 from 2550, we get 804.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8040, and continue the process.

Going ahead to step 10:
8040 divided by 873 is 9 with a remainder of 183.
Record the quotient 9 as the next digit in the result. 
Result so far: 97812.29
The remainder is 183 after subtracting 7857 from 8040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Advancing to step 11:
1830 divided by 873 is 2 with a remainder of 84.
Write down 2 as next digit of the result. 
Result so far: 97812.292
If we take 1746 away from 1830, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 12:
873 can be fit into 840 0 times, resulting in a remainder of 840.
Put 0 as the next digit of the answer. 
Result so far: 97812.292
The remainder is 840 after subtracting 0 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

On to step 13:
873 can be fit into 8400 9 times, resulting in a remainder of 543.
The number 9 becomes the next digit in our result. 
Result so far: 97812.29209
Deduct 7857 from 8400 and we're left with 543.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5430, and continue the process.

Moving on to step 14:
If we divide 5430 by 873, we get 6 and a remainder of 192.
Write down 6 as next digit of the result. 
Result so far: 97812.292096
If we take 5238 away from 5430, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 15:
The number 873 fits into 1920 2 times, leaving a remainder of 174.
The next digit of our result is 2. 
Result so far: 97812.2920962
Subtracting 1746 from 1920 leaves us with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Moving on to step 16:
873 goes into 1740 1 times with a remainder of 867.
Put 1 as the next digit of the answer. 
Result so far: 97812.29209621
Deduct 873 from 1740 and we're left with 867.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8670, and continue the process.

In conclusion, the division gives 97812.29209621 with a balance of 8.67e-07.
