We're dividing 42395141 by 784 
We want to figure out the number of times 42395141 can be divided by 784.

On to step 1:
784 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 784

Let's proceed to step 2:
If we divide 42 by 784, we get 0 and a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Take the next digit (3) from the dividend and append it to 42, then repeat: 423 / 784

Let's proceed to step 3:
The number 784 fits into 423 0 times, leaving a remainder of 423.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 423 after subtracting 0 from 423.
Grab the next digit (9) from the dividend, add it to 423, then carry on: 4239 / 784

Going ahead to step 4:
4239 divided by 784 is 5 with a remainder of 319.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 3920 from 4239 and we're left with 319.
Fetch the next digit (5) from the dividend, attach it to 319 and continue: 3195 / 784

Moving on to step 5:
When dividing 3195 by 784, we get 4 with a remainder of 59.
Put 4 as the next digit of the answer. 
Result so far: 54.0
Deduct 3136 from 3195 and we're left with 59.
Fetch the next digit (1) from the dividend, attach it to 59 and continue: 591 / 784

Let's proceed to step 6:
If we divide 591 by 784, we get 0 and a remainder of 591.
The next digit of our result is 0. 
Result so far: 540.0
Deduct 0 from 591 and we're left with 591.
Include the next digit (4) from the dividend after 591, then repeat: 5914 / 784

Going ahead to step 7:
784 can be fit into 5914 7 times, resulting in a remainder of 426.
Write down 7 as next digit of the result. 
Result so far: 5407.0
If we subtract 5488 from 5914, we get 426.
Take the next digit (1) from the dividend and append it to 426, then repeat: 4261 / 784

Step 8:
4261 divided by 784 is 5 with a remainder of 341.
The next digit of our result is 5. 
Result so far: 54075.0
If we take 3920 away from 4261, we end up with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Advancing to step 9:
784 can be fit into 3410 4 times, resulting in a remainder of 274.
Write down 4 as next digit of the result. 
Result so far: 54075.4
The remainder is 274 after subtracting 3136 from 3410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Let's proceed to step 10:
784 can be fit into 2740 3 times, resulting in a remainder of 388.
The number 3 becomes the next digit in our result. 
Result so far: 54075.43
Subtract 2352 from 2740 to get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Moving on to step 11:
3880 divided by 784 is 4 with a remainder of 744.
Put 4 as the next digit of the answer. 
Result so far: 54075.434
Subtracting 3136 from 3880 leaves us with 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

Step 12:
If we divide 7440 by 784, we get 9 and a remainder of 384.
Write down 9 as next digit of the result. 
Result so far: 54075.4349
If we take 7056 away from 7440, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Going ahead to step 13:
784 goes into 3840 4 times with a remainder of 704.
Record the quotient 4 as the next digit in the result. 
Result so far: 54075.43494
The remainder is 704 after subtracting 3136 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Step 14:
When dividing 7040 by 784, we get 8 with a remainder of 768.
Write down 8 as next digit of the result. 
Result so far: 54075.434948
The remainder is 768 after subtracting 6272 from 7040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

Going ahead to step 15:
784 can be fit into 7680 9 times, resulting in a remainder of 624.
Put 9 as the next digit of the answer. 
Result so far: 54075.4349489
Subtract 7056 from 7680 to 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.

On to step 16:
784 can be fit into 6240 7 times, resulting in a remainder of 752.
Record the quotient 7 as the next digit in the result. 
Result so far: 54075.43494897
The remainder is 752 after subtracting 5488 from 6240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

The final outcome is 54075.43494897, with a leftover of 7.52e-07.
