We look at the division of 77420599 by 522 
We're looking to find how many times 522 goes into 77420599.

Let's proceed to step 1:
The number 522 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.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 522

Let's proceed to step 2:
522 goes into 77 0 times with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Append the next digit (4) from the dividend to 77 and continue with: 774 / 522

Let's proceed to step 3:
522 can be fit into 774 1 times, resulting in a remainder of 252.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 522 from 774 to get 252.
Take the next digit (2) from the dividend and append it to 252, then repeat: 2522 / 522

Advancing to step 4:
522 goes into 2522 4 times with a remainder of 434.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we take 2088 away from 2522, we end up with 434.
Grab the next digit (0) from the dividend, add it to 434, then carry on: 4340 / 522

Moving on to step 5:
4340 divided by 522 is 8 with a remainder of 164.
The next digit of our result is 8. 
Result so far: 148.0
Subtract 4176 from 4340 to get 164.
Include the next digit (5) from the dividend after 164, then repeat: 1645 / 522

Let's proceed to step 6:
The number 522 fits into 1645 3 times, leaving a remainder of 79.
Write down 3 as next digit of the result. 
Result so far: 1483.0
Deduct 1566 from 1645 and we're left with 79.
Take the next digit (9) from the dividend and append it to 79, then repeat: 799 / 522

On to step 7:
799 divided by 522 is 1 with a remainder of 277.
Put 1 as the next digit of the answer. 
Result so far: 14831.0
The remainder is 277 after subtracting 522 from 799.
Include the next digit (9) from the dividend after 277, then repeat: 2779 / 522

Moving on to step 8:
The number 522 fits into 2779 5 times, leaving a remainder of 169.
Put 5 as the next digit of the answer. 
Result so far: 148315.0
Subtract 2610 from 2779 to get 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Moving on to step 9:
When dividing 1690 by 522, we get 3 with a remainder of 124.
The number 3 becomes the next digit in our result. 
Result so far: 148315.3
Deduct 1566 from 1690 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Step 10:
If we divide 1240 by 522, we get 2 and a remainder of 196.
The next digit of our result is 2. 
Result so far: 148315.32
If we subtract 1044 from 1240, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

On to step 11:
522 goes into 1960 3 times with a remainder of 394.
The number 3 becomes the next digit in our result. 
Result so far: 148315.323
If we take 1566 away from 1960, we end up with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Let's proceed to step 12:
If we divide 3940 by 522, we get 7 and a remainder of 286.
The next digit of our result is 7. 
Result so far: 148315.3237
Deduct 3654 from 3940 and we're left with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Moving on to step 13:
When dividing 2860 by 522, we get 5 with a remainder of 250.
Write down 5 as next digit of the result. 
Result so far: 148315.32375
If we take 2610 away from 2860, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 14:
The number 522 fits into 2500 4 times, leaving a remainder of 412.
The number 4 becomes the next digit in our result. 
Result so far: 148315.323754
Subtract 2088 from 2500 to get 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Advancing to step 15:
The number 522 fits into 4120 7 times, leaving a remainder of 466.
Record the quotient 7 as the next digit in the result. 
Result so far: 148315.3237547
The remainder is 466 after subtracting 3654 from 4120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Step 16:
522 goes into 4660 8 times with a remainder of 484.
Put 8 as the next digit of the answer. 
Result so far: 148315.32375478
The remainder is 484 after subtracting 4176 from 4660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

The final outcome is 148315.32375478, with a leftover of 4.84e-07.
