77939073 ÷ 174 
We want to figure out the number of times 77939073 can be divided by 174.

Moving on to step 1:
174 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
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 / 174

Advancing to step 2:
If we divide 77 by 174, we get 0 and a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Fetch the next digit (9) from the dividend, attach it to 77 and continue: 779 / 174

Going ahead to step 3:
174 can be fit into 779 4 times, resulting in a remainder of 83.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 696 from 779 to get 83.
Include the next digit (3) from the dividend after 83, then repeat: 833 / 174

Step 4:
174 goes into 833 4 times with a remainder of 137.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
Deduct 696 from 833 and we're left with 137.
Fetch the next digit (9) from the dividend, attach it to 137 and continue: 1379 / 174

Step 5:
If we divide 1379 by 174, we get 7 and a remainder of 161.
Put 7 as the next digit of the answer. 
Result so far: 447.0
Deduct 1218 from 1379 and we're left with 161.
Fetch the next digit (0) from the dividend, attach it to 161 and continue: 1610 / 174

Advancing to step 6:
If we divide 1610 by 174, we get 9 and a remainder of 44.
Record the quotient 9 as the next digit in the result. 
Result so far: 4479.0
Deduct 1566 from 1610 and we're left with 44.
Include the next digit (7) from the dividend after 44, then repeat: 447 / 174

Let's proceed to step 7:
174 goes into 447 2 times with a remainder of 99.
Use 2 as the next digit of our solution. 
Result so far: 44792.0
Deduct 348 from 447 and we're left with 99.
Take the next digit (3) from the dividend and append it to 99, then repeat: 993 / 174

Advancing to step 8:
174 can be fit into 993 5 times, resulting in a remainder of 123.
Write down 5 as next digit of the result. 
Result so far: 447925.0
The remainder is 123 after subtracting 870 from 993.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Let's proceed to step 9:
174 goes into 1230 7 times with a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 447925.7
The remainder is 12 after subtracting 1218 from 1230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
If we divide 120 by 174, we get 0 and a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 447925.7
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 11:
When dividing 1200 by 174, we get 6 with a remainder of 156.
The next digit of our result is 6. 
Result so far: 447925.706
Subtract 1044 from 1200 to get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Advancing to step 12:
When dividing 1560 by 174, we get 8 with a remainder of 168.
The number 8 becomes the next digit in our result. 
Result so far: 447925.7068
If we subtract 1392 from 1560, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Let's proceed to step 13:
174 can be fit into 1680 9 times, resulting in a remainder of 114.
Put 9 as the next digit of the answer. 
Result so far: 447925.70689
Subtracting 1566 from 1680 leaves us with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Going ahead to step 14:
If we divide 1140 by 174, we get 6 and a remainder of 96.
Put 6 as the next digit of the answer. 
Result so far: 447925.706896
Subtract 1044 from 1140 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 15:
If we divide 960 by 174, we get 5 and a remainder of 90.
The next digit of our result is 5. 
Result so far: 447925.7068965
Subtract 870 from 960 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 16:
When dividing 900 by 174, we get 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 447925.70689655
If we subtract 870 from 900, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 447925.70689655 with a remainder of 3e-08.
