51697648 ÷ 43 
Our goal is to divide 51697648 by 43.

Step 1:
The number 43 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 43

Let's proceed to step 2:
51 divided by 43 is 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 43 from 51 leaves us with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 43

Moving on to step 3:
86 divided by 43 is 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 86 from 86, we get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 43

Let's proceed to step 4:
43 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 120.0
If we subtract 0 from 9, we get 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 43

Moving on to step 5:
When dividing 97 by 43, we get 2 with a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 1202.0
If we take 86 away from 97, we end up with 11.
Bring next digit (6) of the dividend behind the 11 and repeat the process: 116 / 43

Step 6:
If we divide 116 by 43, we get 2 and a remainder of 30.
Record the quotient 2 as the next digit in the result. 
Result so far: 12022.0
Subtracting 86 from 116 leaves us with 30.
Take the next digit (4) from the dividend and append it to 30, then repeat: 304 / 43

Going ahead to step 7:
When dividing 304 by 43, we get 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 120227.0
Subtract 301 from 304 to get 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 43

On to step 8:
The number 43 fits into 38 0 times, leaving a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 1202270.0
Subtracting 0 from 38 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 9:
If we divide 380 by 43, we get 8 and a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 1202270.8
If we take 344 away from 380, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 10:
43 goes into 360 8 times with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 1202270.88
The remainder is 16 after subtracting 344 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 1202270.88, and the remainder is 0.016.
