We're dividing 43319700 by 51 
We want to divide 43319700 by 51.

Moving on to step 1:
If we divide 4 by 51, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 51

On to step 2:
When dividing 43 by 51, we get 0 with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Bring next digit (3) of the dividend behind the 43 and repeat the process: 433 / 51

Moving on to step 3:
The number 51 fits into 433 8 times, leaving a remainder of 25.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 408 from 433 to get 25.
Bring next digit (1) of the dividend behind the 25 and repeat the process: 251 / 51

Going ahead to step 4:
If we divide 251 by 51, we get 4 and a remainder of 47.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
Subtract 204 from 251 to get 47.
Append the next digit (9) from the dividend to 47 and continue with: 479 / 51

Going ahead to step 5:
51 goes into 479 9 times with a remainder of 20.
Use 9 as the next digit of our solution. 
Result so far: 849.0
If we subtract 459 from 479, we get 20.
Fetch the next digit (7) from the dividend, attach it to 20 and continue: 207 / 51

Moving on to step 6:
51 goes into 207 4 times with a remainder of 3.
The next digit of our result is 4. 
Result so far: 8494.0
Subtracting 204 from 207 leaves us with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 51

Advancing to step 7:
51 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 84940.0
Deduct 0 from 30 and we're left with 30.
Append the next digit (0) from the dividend to 30 and continue with: 300 / 51

Moving on to step 8:
If we divide 300 by 51, we get 5 and a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 849405.0
The remainder is 45 after subtracting 255 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 9:
51 can be fit into 450 8 times, resulting in a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 849405.8
Subtract 408 from 450 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 10:
When dividing 420 by 51, we get 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 849405.88
Deduct 408 from 420 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 849405.88 with a remainder of 0.012.
