We look at the division of 77052487 by 42 
Our goal is to divide 77052487 by 42.

Step 1:
The number 42 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 42

Going ahead to step 2:
42 can be fit into 77 1 times, resulting in a remainder of 35.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 42 from 77 leaves us with 35.
Include the next digit (0) from the dividend after 35, then repeat: 350 / 42

Let's proceed to step 3:
When dividing 350 by 42, we get 8 with a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
The remainder is 14 after subtracting 336 from 350.
Bring next digit (5) of the dividend behind the 14 and repeat the process: 145 / 42

Going ahead to step 4:
42 goes into 145 3 times with a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 183.0
If we subtract 126 from 145, we get 19.
Grab the next digit (2) from the dividend, add it to 19, then carry on: 192 / 42

Advancing to step 5:
42 goes into 192 4 times with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 1834.0
Subtracting 168 from 192 leaves us with 24.
Include the next digit (4) from the dividend after 24, then repeat: 244 / 42

Let's proceed to step 6:
42 goes into 244 5 times with a remainder of 34.
The number 5 becomes the next digit in our result. 
Result so far: 18345.0
Subtract 210 from 244 to get 34.
Grab the next digit (8) from the dividend, add it to 34, then carry on: 348 / 42

On to step 7:
42 can be fit into 348 8 times, resulting in a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 183458.0
If we subtract 336 from 348, we get 12.
Append the next digit (7) from the dividend to 12 and continue with: 127 / 42

Moving on to step 8:
42 goes into 127 3 times with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 1834583.0
Deduct 126 from 127 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
If we divide 10 by 42, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 1834583.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
42 goes into 100 2 times with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 1834583.02
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
42 goes into 160 3 times with a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 1834583.023
The remainder is 34 after subtracting 126 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 12:
The number 42 fits into 340 8 times, leaving a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 1834583.0238
Subtracting 336 from 340 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 13:
42 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 1834583.0238
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 14:
When dividing 400 by 42, we get 9 with a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 1834583.023809
Deduct 378 from 400 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 15:
The number 42 fits into 220 5 times, leaving a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 1834583.0238095
Subtracting 210 from 220 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 16:
100 divided by 42 is 2 with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 1834583.02380952
If we take 84 away from 100, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 1834583.02380952, with a leftover of 1.6e-08.
