Let's divide 507821 by 43
We're looking to find how many times 43 goes into 507821.

Going ahead to step 1:
If we divide 5 by 43, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 43

Going ahead to step 2:
The number 43 fits into 50 1 times, leaving a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 43 away from 50, we end up with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 43

Step 3:
If we divide 77 by 43, we get 1 and a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 43 from 77, we get 34.
Grab the next digit (8) from the dividend, add it to 34, then carry on: 348 / 43

Advancing to step 4:
If we divide 348 by 43, we get 8 and a remainder of 4.
The next digit of our result is 8. 
Result so far: 118.0
Deduct 344 from 348 and we're left with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 43

Advancing to step 5:
43 can be fit into 42 0 times, resulting in a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 1180.0
Deduct 0 from 42 and we're left with 42.
Append the next digit (1) from the dividend to 42 and continue with: 421 / 43

Advancing to step 6:
When dividing 421 by 43, we get 9 with a remainder of 34.
The number 9 becomes the next digit in our result. 
Result so far: 11809.0
The remainder is 34 after subtracting 387 from 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 7:
The number 43 fits into 340 7 times, leaving a remainder of 39.
Write down 7 as next digit of the result. 
Result so far: 11809.7
If we subtract 301 from 340, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 8:
When dividing 390 by 43, we get 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 11809.79
If we take 387 away from 390, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 9:
30 divided by 43 is 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 11809.79
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
43 goes into 300 6 times with a remainder of 42.
Use 6 as the next digit of our solution. 
Result so far: 11809.7906
Deduct 258 from 300 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 11:
The number 43 fits into 420 9 times, leaving a remainder of 33.
Use 9 as the next digit of our solution. 
Result so far: 11809.79069
The remainder is 33 after subtracting 387 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 12:
The number 43 fits into 330 7 times, leaving a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 11809.790697
If we subtract 301 from 330, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 13:
43 can be fit into 290 6 times, resulting in a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 11809.7906976
Subtract 258 from 290 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 14:
320 divided by 43 is 7 with a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 11809.79069767
Deduct 301 from 320 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final outcome is 11809.79069767, with a leftover of 1.9e-08.
