56389485 ÷ 42 
We're looking to find how many times 42 goes into 56389485.

Moving on to step 1:
5 divided by 42 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 42

Step 2:
56 divided by 42 is 1 with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 42 away from 56, we end up with 14.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 42

Let's proceed to step 3:
If we divide 143 by 42, we get 3 and a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtract 126 from 143 to get 17.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 42

Advancing to step 4:
When dividing 178 by 42, we get 4 with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 134.0
Subtract 168 from 178 to get 10.
Take the next digit (9) from the dividend and append it to 10, then repeat: 109 / 42

Moving on to step 5:
109 divided by 42 is 2 with a remainder of 25.
Put 2 as the next digit of the answer. 
Result so far: 1342.0
Subtract 84 from 109 to get 25.
Include the next digit (4) from the dividend after 25, then repeat: 254 / 42

Let's proceed to step 6:
The number 42 fits into 254 6 times, leaving a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 13426.0
If we subtract 252 from 254, we get 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 42

Moving on to step 7:
42 goes into 28 0 times with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 134260.0
Subtracting 0 from 28 leaves us with 28.
Fetch the next digit (5) from the dividend, attach it to 28 and continue: 285 / 42

On to step 8:
285 divided by 42 is 6 with a remainder of 33.
The next digit of our result is 6. 
Result so far: 1342606.0
Subtract 252 from 285 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 9:
The number 42 fits into 330 7 times, leaving a remainder of 36.
The number 7 becomes the next digit in our result. 
Result so far: 1342606.7
Deduct 294 from 330 and we're left 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:
42 can be fit into 360 8 times, resulting in a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 1342606.78
If we take 336 away from 360, we end up 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.

On to step 11:
42 can be fit into 240 5 times, resulting in a remainder of 30.
The next digit of our result is 5. 
Result so far: 1342606.785
Subtracting 210 from 240 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 12:
The number 42 fits into 300 7 times, leaving a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 1342606.7857
Subtract 294 from 300 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 13:
42 can be fit into 60 1 times, resulting in a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 1342606.78571
Subtract 42 from 60 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 14:
42 goes into 180 4 times with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 1342606.785714
If we take 168 away from 180, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 15:
The number 42 fits into 120 2 times, leaving a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 1342606.7857142
The remainder is 36 after subtracting 84 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 16:
42 goes into 360 8 times with a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 1342606.78571428
Subtracting 336 from 360 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.

The final outcome is 1342606.78571428, with a leftover of 2.4e-08.
