We're dividing 42394966 by 538 
We want to divide 42394966 by 538.

Advancing to step 1:
When dividing 4 by 538, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 538

Advancing to step 2:
When dividing 42 by 538, we get 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Include the next digit (3) from the dividend after 42, then repeat: 423 / 538

Let's proceed to step 3:
538 can be fit into 423 0 times, resulting in a remainder of 423.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 423, we get 423.
Append the next digit (9) from the dividend to 423 and continue with: 4239 / 538

On to step 4:
When dividing 4239 by 538, we get 7 with a remainder of 473.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 3766 from 4239 leaves us with 473.
Fetch the next digit (4) from the dividend, attach it to 473 and continue: 4734 / 538

Advancing to step 5:
If we divide 4734 by 538, we get 8 and a remainder of 430.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
If we subtract 4304 from 4734, we get 430.
Append the next digit (9) from the dividend to 430 and continue with: 4309 / 538

On to step 6:
538 can be fit into 4309 8 times, resulting in a remainder of 5.
Put 8 as the next digit of the answer. 
Result so far: 788.0
Deduct 4304 from 4309 and we're left with 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 538

Going ahead to step 7:
The number 538 fits into 56 0 times, leaving a remainder of 56.
The next digit of our result is 0. 
Result so far: 7880.0
If we subtract 0 from 56, we get 56.
Take the next digit (6) from the dividend and append it to 56, then repeat: 566 / 538

Moving on to step 8:
When dividing 566 by 538, we get 1 with a remainder of 28.
Put 1 as the next digit of the answer. 
Result so far: 78801.0
Subtract 538 from 566 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 9:
538 can be fit into 280 0 times, resulting in a remainder of 280.
The next digit of our result is 0. 
Result so far: 78801.0
Subtract 0 from 280 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 10:
538 goes into 2800 5 times with a remainder of 110.
Use 5 as the next digit of our solution. 
Result so far: 78801.05
Subtract 2690 from 2800 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 11:
538 goes into 1100 2 times with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 78801.052
Subtracting 1076 from 1100 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 12:
538 can be fit into 240 0 times, resulting in a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 78801.052
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 13:
538 can be fit into 2400 4 times, resulting in a remainder of 248.
The next digit of our result is 4. 
Result so far: 78801.05204
If we subtract 2152 from 2400, we get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Advancing to step 14:
2480 divided by 538 is 4 with a remainder of 328.
Write down 4 as next digit of the result. 
Result so far: 78801.052044
Subtracting 2152 from 2480 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

The final outcome is 78801.052044, with a leftover of 3.28e-05.
