We look at the division of 42017224 by 784 
We want to divide 42017224 by 784.

On to step 1:
When dividing 4 by 784, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 784

On to step 2:
If we divide 42 by 784, we get 0 and a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Append the next digit (0) from the dividend to 42 and continue with: 420 / 784

Advancing to step 3:
420 divided by 784 is 0 with a remainder of 420.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 420 to get 420.
Take the next digit (1) from the dividend and append it to 420, then repeat: 4201 / 784

Advancing to step 4:
The number 784 fits into 4201 5 times, leaving a remainder of 281.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 3920 from 4201 leaves us with 281.
Include the next digit (7) from the dividend after 281, then repeat: 2817 / 784

Advancing to step 5:
2817 divided by 784 is 3 with a remainder of 465.
Put 3 as the next digit of the answer. 
Result so far: 53.0
Subtract 2352 from 2817 to get 465.
Take the next digit (2) from the dividend and append it to 465, then repeat: 4652 / 784

Advancing to step 6:
4652 divided by 784 is 5 with a remainder of 732.
The next digit of our result is 5. 
Result so far: 535.0
If we subtract 3920 from 4652, we get 732.
Grab the next digit (2) from the dividend, add it to 732, then carry on: 7322 / 784

Step 7:
When dividing 7322 by 784, we get 9 with a remainder of 266.
The number 9 becomes the next digit in our result. 
Result so far: 5359.0
Deduct 7056 from 7322 and we're left with 266.
Grab the next digit (4) from the dividend, add it to 266, then carry on: 2664 / 784

On to step 8:
When dividing 2664 by 784, we get 3 with a remainder of 312.
The number 3 becomes the next digit in our result. 
Result so far: 53593.0
If we subtract 2352 from 2664, we get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

On to step 9:
When dividing 3120 by 784, we get 3 with a remainder of 768.
The next digit of our result is 3. 
Result so far: 53593.3
If we take 2352 away from 3120, we end up with 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

On to step 10:
784 can be fit into 7680 9 times, resulting in a remainder of 624.
Use 9 as the next digit of our solution. 
Result so far: 53593.39
If we subtract 7056 from 7680, we get 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Going ahead to step 11:
The number 784 fits into 6240 7 times, leaving a remainder of 752.
The number 7 becomes the next digit in our result. 
Result so far: 53593.397
Deduct 5488 from 6240 and we're left with 752.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

On to step 12:
784 can be fit into 7520 9 times, resulting in a remainder of 464.
Put 9 as the next digit of the answer. 
Result so far: 53593.3979
If we subtract 7056 from 7520, we get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Step 13:
If we divide 4640 by 784, we get 5 and a remainder of 720.
Record the quotient 5 as the next digit in the result. 
Result so far: 53593.39795
If we subtract 3920 from 4640, we get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Let's proceed to step 14:
784 can be fit into 7200 9 times, resulting in a remainder of 144.
Put 9 as the next digit of the answer. 
Result so far: 53593.397959
If we subtract 7056 from 7200, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 15:
The number 784 fits into 1440 1 times, leaving a remainder of 656.
Write down 1 as next digit of the result. 
Result so far: 53593.3979591
Subtract 784 from 1440 to get 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Advancing to step 16:
When dividing 6560 by 784, we get 8 with a remainder of 288.
The next digit of our result is 8. 
Result so far: 53593.39795918
Deduct 6272 from 6560 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

In conclusion, the division gives 53593.39795918 with a balance of 2.88e-07.
