84685931 ÷ 857 
We're looking to find how many times 857 goes into 84685931.

Let's proceed to step 1:
The number 857 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 857

On to step 2:
857 can be fit into 84 0 times, resulting in a remainder of 84.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 84 to get 84.
Append the next digit (6) from the dividend to 84 and continue with: 846 / 857

Step 3:
857 goes into 846 0 times with a remainder of 846.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 846 leaves us with 846.
Fetch the next digit (8) from the dividend, attach it to 846 and continue: 8468 / 857

Let's proceed to step 4:
The number 857 fits into 8468 9 times, leaving a remainder of 755.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 7713 from 8468 leaves us with 755.
Take the next digit (5) from the dividend and append it to 755, then repeat: 7555 / 857

Step 5:
857 can be fit into 7555 8 times, resulting in a remainder of 699.
Use 8 as the next digit of our solution. 
Result so far: 98.0
If we subtract 6856 from 7555, we get 699.
Bring next digit (9) of the dividend behind the 699 and repeat the process: 6999 / 857

Step 6:
When dividing 6999 by 857, we get 8 with a remainder of 143.
Record the quotient 8 as the next digit in the result. 
Result so far: 988.0
If we subtract 6856 from 6999, we get 143.
Bring next digit (3) of the dividend behind the 143 and repeat the process: 1433 / 857

Step 7:
When dividing 1433 by 857, we get 1 with a remainder of 576.
Write down 1 as next digit of the result. 
Result so far: 9881.0
Deduct 857 from 1433 and we're left with 576.
Bring next digit (1) of the dividend behind the 576 and repeat the process: 5761 / 857

Step 8:
5761 divided by 857 is 6 with a remainder of 619.
Use 6 as the next digit of our solution. 
Result so far: 98816.0
If we subtract 5142 from 5761, we get 619.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6190, and continue the process.

Let's proceed to step 9:
6190 divided by 857 is 7 with a remainder of 191.
Write down 7 as next digit of the result. 
Result so far: 98816.7
If we subtract 5999 from 6190, we get 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Let's proceed to step 10:
If we divide 1910 by 857, we get 2 and a remainder of 196.
Record the quotient 2 as the next digit in the result. 
Result so far: 98816.72
The remainder is 196 after subtracting 1714 from 1910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Moving on to step 11:
857 can be fit into 1960 2 times, resulting in a remainder of 246.
The number 2 becomes the next digit in our result. 
Result so far: 98816.722
If we subtract 1714 from 1960, we get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

In conclusion, the division gives 98816.722 with a balance of 0.0246.
