Let's divide 23259689 by 431
Let's see how many times 431 fits into 23259689.

Advancing to step 1:
431 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 431

On to step 2:
When dividing 23 by 431, we get 0 with a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 23 after subtracting 0 from 23.
Include the next digit (2) from the dividend after 23, then repeat: 232 / 431

Advancing to step 3:
431 goes into 232 0 times with a remainder of 232.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 232 and we're left with 232.
Bring next digit (5) of the dividend behind the 232 and repeat the process: 2325 / 431

On to step 4:
431 goes into 2325 5 times with a remainder of 170.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 2155 from 2325 and we're left with 170.
Grab the next digit (9) from the dividend, add it to 170, then carry on: 1709 / 431

On to step 5:
1709 divided by 431 is 3 with a remainder of 416.
Use 3 as the next digit of our solution. 
Result so far: 53.0
If we subtract 1293 from 1709, we get 416.
Take the next digit (6) from the dividend and append it to 416, then repeat: 4166 / 431

On to step 6:
431 can be fit into 4166 9 times, resulting in a remainder of 287.
Put 9 as the next digit of the answer. 
Result so far: 539.0
Subtract 3879 from 4166 to get 287.
Take the next digit (8) from the dividend and append it to 287, then repeat: 2878 / 431

On to step 7:
431 goes into 2878 6 times with a remainder of 292.
Use 6 as the next digit of our solution. 
Result so far: 5396.0
If we take 2586 away from 2878, we end up with 292.
Grab the next digit (9) from the dividend, add it to 292, then carry on: 2929 / 431

Moving on to step 8:
431 goes into 2929 6 times with a remainder of 343.
Put 6 as the next digit of the answer. 
Result so far: 53966.0
Deduct 2586 from 2929 and we're left with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Let's proceed to step 9:
The number 431 fits into 3430 7 times, leaving a remainder of 413.
Use 7 as the next digit of our solution. 
Result so far: 53966.7
If we subtract 3017 from 3430, we get 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

Going ahead to step 10:
If we divide 4130 by 431, we get 9 and a remainder of 251.
The next digit of our result is 9. 
Result so far: 53966.79
Subtracting 3879 from 4130 leaves us with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Step 11:
The number 431 fits into 2510 5 times, leaving a remainder of 355.
Record the quotient 5 as the next digit in the result. 
Result so far: 53966.795
Deduct 2155 from 2510 and we're left with 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Let's proceed to step 12:
If we divide 3550 by 431, we get 8 and a remainder of 102.
The next digit of our result is 8. 
Result so far: 53966.7958
If we take 3448 away from 3550, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

On to step 13:
431 can be fit into 1020 2 times, resulting in a remainder of 158.
The number 2 becomes the next digit in our result. 
Result so far: 53966.79582
Subtract 862 from 1020 to get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Advancing to step 14:
1580 divided by 431 is 3 with a remainder of 287.
Record the quotient 3 as the next digit in the result. 
Result so far: 53966.795823
The remainder is 287 after subtracting 1293 from 1580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Let's proceed to step 15:
431 can be fit into 2870 6 times, resulting in a remainder of 284.
Use 6 as the next digit of our solution. 
Result so far: 53966.7958236
If we subtract 2586 from 2870, we get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Going ahead to step 16:
The number 431 fits into 2840 6 times, leaving a remainder of 254.
Use 6 as the next digit of our solution. 
Result so far: 53966.79582366
Deduct 2586 from 2840 and we're left with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

The final outcome is 53966.79582366, with a leftover of 2.54e-07.
