77042436 ÷ 171 
We want to figure out the number of times 77042436 can be divided by 171.

Step 1:
7 divided by 171 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 171

Step 2:
When dividing 77 by 171, we get 0 with a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Grab the next digit (0) from the dividend, add it to 77, then carry on: 770 / 171

Step 3:
171 goes into 770 4 times with a remainder of 86.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 684 from 770 to get 86.
Bring next digit (4) of the dividend behind the 86 and repeat the process: 864 / 171

Advancing to step 4:
171 can be fit into 864 5 times, resulting in a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 45.0
If we subtract 855 from 864, we get 9.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 171

Moving on to step 5:
171 can be fit into 92 0 times, resulting in a remainder of 92.
Put 0 as the next digit of the answer. 
Result so far: 450.0
Subtract 0 from 92 to get 92.
Bring next digit (4) of the dividend behind the 92 and repeat the process: 924 / 171

Going ahead to step 6:
When dividing 924 by 171, we get 5 with a remainder of 69.
Use 5 as the next digit of our solution. 
Result so far: 4505.0
Subtracting 855 from 924 leaves us with 69.
Include the next digit (3) from the dividend after 69, then repeat: 693 / 171

Step 7:
171 can be fit into 693 4 times, resulting in a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 45054.0
Deduct 684 from 693 and we're left with 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 171

Moving on to step 8:
When dividing 96 by 171, we get 0 with a remainder of 96.
Use 0 as the next digit of our solution. 
Result so far: 450540.0
If we take 0 away from 96, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 9:
When dividing 960 by 171, we get 5 with a remainder of 105.
Put 5 as the next digit of the answer. 
Result so far: 450540.5
Subtracting 855 from 960 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Going ahead to step 10:
If we divide 1050 by 171, we get 6 and a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 450540.56
The remainder is 24 after subtracting 1026 from 1050.
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:
171 can be fit into 240 1 times, resulting in a remainder of 69.
Put 1 as the next digit of the answer. 
Result so far: 450540.561
Deduct 171 from 240 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 12:
171 can be fit into 690 4 times, resulting in a remainder of 6.
The next digit of our result is 4. 
Result so far: 450540.5614
The remainder is 6 after subtracting 684 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 13:
When dividing 60 by 171, we get 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 450540.5614
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 14:
When dividing 600 by 171, we get 3 with a remainder of 87.
Use 3 as the next digit of our solution. 
Result so far: 450540.561403
The remainder is 87 after subtracting 513 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Advancing to step 15:
171 can be fit into 870 5 times, resulting in a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 450540.5614035
Deduct 855 from 870 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 16:
171 goes into 150 0 times with a remainder of 150.
Record the quotient 0 as the next digit in the result. 
Result so far: 450540.5614035
If we take 0 away from 150, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

The final outcome is 450540.5614035, with a leftover of 1.5e-07.
