We're dividing 99710589 by 431 
Let's see how many times 431 fits into 99710589.

Step 1:
431 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 431

Moving on to step 2:
If we divide 99 by 431, we get 0 and a remainder of 99.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 99 to get 99.
Include the next digit (7) from the dividend after 99, then repeat: 997 / 431

Moving on to step 3:
997 divided by 431 is 2 with a remainder of 135.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 135 after subtracting 862 from 997.
Include the next digit (1) from the dividend after 135, then repeat: 1351 / 431

Moving on to step 4:
The number 431 fits into 1351 3 times, leaving a remainder of 58.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Deduct 1293 from 1351 and we're left with 58.
Grab the next digit (0) from the dividend, add it to 58, then carry on: 580 / 431

Advancing to step 5:
431 goes into 580 1 times with a remainder of 149.
Use 1 as the next digit of our solution. 
Result so far: 231.0
Deduct 431 from 580 and we're left with 149.
Append the next digit (5) from the dividend to 149 and continue with: 1495 / 431

Moving on to step 6:
The number 431 fits into 1495 3 times, leaving a remainder of 202.
Put 3 as the next digit of the answer. 
Result so far: 2313.0
Subtract 1293 from 1495 to get 202.
Append the next digit (8) from the dividend to 202 and continue with: 2028 / 431

Step 7:
If we divide 2028 by 431, we get 4 and a remainder of 304.
The next digit of our result is 4. 
Result so far: 23134.0
The remainder is 304 after subtracting 1724 from 2028.
Grab the next digit (9) from the dividend, add it to 304, then carry on: 3049 / 431

Moving on to step 8:
The number 431 fits into 3049 7 times, leaving a remainder of 32.
The next digit of our result is 7. 
Result so far: 231347.0
If we take 3017 away from 3049, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 9:
When dividing 320 by 431, we get 0 with a remainder of 320.
Record the quotient 0 as the next digit in the result. 
Result so far: 231347.0
Subtracting 0 from 320 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 10:
431 goes into 3200 7 times with a remainder of 183.
Put 7 as the next digit of the answer. 
Result so far: 231347.07
If we take 3017 away from 3200, we end up with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

On to step 11:
1830 divided by 431 is 4 with a remainder of 106.
Use 4 as the next digit of our solution. 
Result so far: 231347.074
If we subtract 1724 from 1830, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 12:
The number 431 fits into 1060 2 times, leaving a remainder of 198.
The next digit of our result is 2. 
Result so far: 231347.0742
Subtracting 862 from 1060 leaves us with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Step 13:
431 can be fit into 1980 4 times, resulting in a remainder of 256.
The number 4 becomes the next digit in our result. 
Result so far: 231347.07424
If we take 1724 away from 1980, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

On to step 14:
When dividing 2560 by 431, we get 5 with a remainder of 405.
The next digit of our result is 5. 
Result so far: 231347.074245
Subtract 2155 from 2560 to get 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

On to step 15:
4050 divided by 431 is 9 with a remainder of 171.
The number 9 becomes the next digit in our result. 
Result so far: 231347.0742459
Deduct 3879 from 4050 and we're left with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Let's proceed to step 16:
1710 divided by 431 is 3 with a remainder of 417.
Record the quotient 3 as the next digit in the result. 
Result so far: 231347.07424593
Subtract 1293 from 1710 to get 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

The final result is 231347.07424593 with a remainder of 4.17e-07.
