We're dividing 78522931 by 105 
The aim is to understand the frequency of 105 in 78522931.

Advancing to step 1:
105 can be fit into 7 0 times, resulting in 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.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 105

Step 2:
78 divided by 105 is 0 with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Fetch the next digit (5) from the dividend, attach it to 78 and continue: 785 / 105

Let's proceed to step 3:
When dividing 785 by 105, we get 7 with a remainder of 50.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 50 after subtracting 735 from 785.
Append the next digit (2) from the dividend to 50 and continue with: 502 / 105

Let's proceed to step 4:
The number 105 fits into 502 4 times, leaving a remainder of 82.
Use 4 as the next digit of our solution. 
Result so far: 74.0
If we subtract 420 from 502, we get 82.
Take the next digit (2) from the dividend and append it to 82, then repeat: 822 / 105

Let's proceed to step 5:
822 divided by 105 is 7 with a remainder of 87.
Record the quotient 7 as the next digit in the result. 
Result so far: 747.0
Subtracting 735 from 822 leaves us with 87.
Fetch the next digit (9) from the dividend, attach it to 87 and continue: 879 / 105

Advancing to step 6:
The number 105 fits into 879 8 times, leaving a remainder of 39.
The next digit of our result is 8. 
Result so far: 7478.0
If we subtract 840 from 879, we get 39.
Bring next digit (3) of the dividend behind the 39 and repeat the process: 393 / 105

On to step 7:
393 divided by 105 is 3 with a remainder of 78.
Use 3 as the next digit of our solution. 
Result so far: 74783.0
The remainder is 78 after subtracting 315 from 393.
Grab the next digit (1) from the dividend, add it to 78, then carry on: 781 / 105

On to step 8:
105 can be fit into 781 7 times, resulting in a remainder of 46.
Use 7 as the next digit of our solution. 
Result so far: 747837.0
Subtract 735 from 781 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 9:
460 divided by 105 is 4 with a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 747837.4
If we take 420 away from 460, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
When dividing 400 by 105, we get 3 with a remainder of 85.
Use 3 as the next digit of our solution. 
Result so far: 747837.43
If we subtract 315 from 400, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 11:
The number 105 fits into 850 8 times, leaving a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 747837.438
Deduct 840 from 850 and we're left 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 12:
The number 105 fits into 100 0 times, leaving a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 747837.438
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 13:
When dividing 1000 by 105, we get 9 with a remainder of 55.
Use 9 as the next digit of our solution. 
Result so far: 747837.43809
Deduct 945 from 1000 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 14:
If we divide 550 by 105, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 747837.438095
If we take 525 away from 550, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 15:
105 can be fit into 250 2 times, resulting in a remainder of 40.
The next digit of our result is 2. 
Result so far: 747837.4380952
The remainder is 40 after subtracting 210 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 16:
105 can be fit into 400 3 times, resulting in a remainder of 85.
Write down 3 as next digit of the result. 
Result so far: 747837.43809523
Subtracting 315 from 400 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

The final result is 747837.43809523 with a remainder of 8.5e-08.
