We're dividing 51866519 by 742 
Let's see how many times 742 fits into 51866519.

On to step 1:
The number 742 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 742

Moving on to step 2:
742 can be fit into 51 0 times, resulting in a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Include the next digit (8) from the dividend after 51, then repeat: 518 / 742

Step 3:
518 divided by 742 is 0 with a remainder of 518.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 518, we end up with 518.
Include the next digit (6) from the dividend after 518, then repeat: 5186 / 742

Step 4:
742 goes into 5186 6 times with a remainder of 734.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 4452 away from 5186, we end up with 734.
Grab the next digit (6) from the dividend, add it to 734, then carry on: 7346 / 742

Let's proceed to step 5:
The number 742 fits into 7346 9 times, leaving a remainder of 668.
The number 9 becomes the next digit in our result. 
Result so far: 69.0
Subtract 6678 from 7346 to get 668.
Append the next digit (5) from the dividend to 668 and continue with: 6685 / 742

Step 6:
742 goes into 6685 9 times with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 699.0
If we subtract 6678 from 6685, we get 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 742

Moving on to step 7:
71 divided by 742 is 0 with a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 6990.0
Subtracting 0 from 71 leaves us with 71.
Append the next digit (9) from the dividend to 71 and continue with: 719 / 742

Step 8:
When dividing 719 by 742, we get 0 with a remainder of 719.
Put 0 as the next digit of the answer. 
Result so far: 69900.0
If we take 0 away from 719, we end up with 719.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7190, and continue the process.

On to step 9:
742 can be fit into 7190 9 times, resulting in a remainder of 512.
Use 9 as the next digit of our solution. 
Result so far: 69900.9
The remainder is 512 after subtracting 6678 from 7190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Let's proceed to step 10:
If we divide 5120 by 742, we get 6 and a remainder of 668.
Use 6 as the next digit of our solution. 
Result so far: 69900.96
If we take 4452 away from 5120, we end up with 668.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

Going ahead to step 11:
The number 742 fits into 6680 9 times, leaving a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 69900.969
Subtract 6678 from 6680 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 12:
When dividing 20 by 742, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 69900.969
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 13:
If we divide 200 by 742, we get 0 and a remainder of 200.
The next digit of our result is 0. 
Result so far: 69900.969
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

In conclusion, the division gives 69900.969 with a balance of 0.0002.
