We're dividing 88398931 by 973 
We want to figure out the number of times 88398931 can be divided by 973.

Step 1:
8 divided by 973 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 973

Let's proceed to step 2:
The number 973 fits into 88 0 times, leaving a remainder of 88.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 88, we end up with 88.
Take the next digit (3) from the dividend and append it to 88, then repeat: 883 / 973

Let's proceed to step 3:
883 divided by 973 is 0 with a remainder of 883.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 883, we get 883.
Grab the next digit (9) from the dividend, add it to 883, then carry on: 8839 / 973

Let's proceed to step 4:
8839 divided by 973 is 9 with a remainder of 82.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 8757 from 8839 leaves us with 82.
Grab the next digit (8) from the dividend, add it to 82, then carry on: 828 / 973

Going ahead to step 5:
The number 973 fits into 828 0 times, leaving a remainder of 828.
The number 0 becomes the next digit in our result. 
Result so far: 90.0
Subtract 0 from 828 to get 828.
Bring next digit (9) of the dividend behind the 828 and repeat the process: 8289 / 973

Moving on to step 6:
973 goes into 8289 8 times with a remainder of 505.
Use 8 as the next digit of our solution. 
Result so far: 908.0
If we subtract 7784 from 8289, we get 505.
Append the next digit (3) from the dividend to 505 and continue with: 5053 / 973

Step 7:
If we divide 5053 by 973, we get 5 and a remainder of 188.
Record the quotient 5 as the next digit in the result. 
Result so far: 9085.0
If we subtract 4865 from 5053, we get 188.
Include the next digit (1) from the dividend after 188, then repeat: 1881 / 973

On to step 8:
1881 divided by 973 is 1 with a remainder of 908.
Use 1 as the next digit of our solution. 
Result so far: 90851.0
Subtract 973 from 1881 to get 908.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9080, and continue the process.

Let's proceed to step 9:
973 can be fit into 9080 9 times, resulting in a remainder of 323.
Use 9 as the next digit of our solution. 
Result so far: 90851.9
If we take 8757 away from 9080, we end up with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Step 10:
973 can be fit into 3230 3 times, resulting in a remainder of 311.
The number 3 becomes the next digit in our result. 
Result so far: 90851.93
The remainder is 311 after subtracting 2919 from 3230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Let's proceed to step 11:
If we divide 3110 by 973, we get 3 and a remainder of 191.
The next digit of our result is 3. 
Result so far: 90851.933
If we subtract 2919 from 3110, 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.

The final result is 90851.933 with a remainder of 0.0191.
