78052611 divided by 522 
The aim is to understand the frequency of 522 in 78052611.

Going ahead to step 1:
522 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 522

Going ahead to step 2:
If we divide 78 by 522, we get 0 and a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Fetch the next digit (0) from the dividend, attach it to 78 and continue: 780 / 522

Step 3:
522 can be fit into 780 1 times, resulting in a remainder of 258.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 522 from 780 to get 258.
Grab the next digit (5) from the dividend, add it to 258, then carry on: 2585 / 522

Going ahead to step 4:
522 can be fit into 2585 4 times, resulting in a remainder of 497.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 2088 from 2585, we get 497.
Include the next digit (2) from the dividend after 497, then repeat: 4972 / 522

Advancing to step 5:
4972 divided by 522 is 9 with a remainder of 274.
Record the quotient 9 as the next digit in the result. 
Result so far: 149.0
Deduct 4698 from 4972 and we're left with 274.
Fetch the next digit (6) from the dividend, attach it to 274 and continue: 2746 / 522

Advancing to step 6:
When dividing 2746 by 522, we get 5 with a remainder of 136.
Write down 5 as next digit of the result. 
Result so far: 1495.0
Subtract 2610 from 2746 to get 136.
Grab the next digit (1) from the dividend, add it to 136, then carry on: 1361 / 522

Advancing to step 7:
When dividing 1361 by 522, we get 2 with a remainder of 317.
The number 2 becomes the next digit in our result. 
Result so far: 14952.0
Subtracting 1044 from 1361 leaves us with 317.
Grab the next digit (1) from the dividend, add it to 317, then carry on: 3171 / 522

Moving on to step 8:
3171 divided by 522 is 6 with a remainder of 39.
The number 6 becomes the next digit in our result. 
Result so far: 149526.0
If we take 3132 away from 3171, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 9:
522 can be fit into 390 0 times, resulting in a remainder of 390.
Put 0 as the next digit of the answer. 
Result so far: 149526.0
Subtract 0 from 390 to get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Going ahead to step 10:
3900 divided by 522 is 7 with a remainder of 246.
The next digit of our result is 7. 
Result so far: 149526.07
Deduct 3654 from 3900 and we're left with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Step 11:
522 goes into 2460 4 times with a remainder of 372.
Use 4 as the next digit of our solution. 
Result so far: 149526.074
The remainder is 372 after subtracting 2088 from 2460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Step 12:
If we divide 3720 by 522, we get 7 and a remainder of 66.
Record the quotient 7 as the next digit in the result. 
Result so far: 149526.0747
If we take 3654 away from 3720, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 13:
When dividing 660 by 522, we get 1 with a remainder of 138.
The next digit of our result is 1. 
Result so far: 149526.07471
If we subtract 522 from 660, we get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Going ahead to step 14:
522 goes into 1380 2 times with a remainder of 336.
Put 2 as the next digit of the answer. 
Result so far: 149526.074712
Subtract 1044 from 1380 to get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

On to step 15:
522 can be fit into 3360 6 times, resulting in a remainder of 228.
Put 6 as the next digit of the answer. 
Result so far: 149526.0747126
Subtracting 3132 from 3360 leaves us with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Advancing to step 16:
522 goes into 2280 4 times with a remainder of 192.
The next digit of our result is 4. 
Result so far: 149526.07471264
Deduct 2088 from 2280 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

After the division, we end up with 149526.07471264 and a remainder of 1.92e-07.
