We're dividing 78623575 by 788 
The aim is to understand the frequency of 788 in 78623575.

On to step 1:
788 can be fit into 7 0 times, resulting in 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.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 788

Advancing to step 2:
The number 788 fits into 78 0 times, leaving a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Grab the next digit (6) from the dividend, add it to 78, then carry on: 786 / 788

Advancing to step 3:
If we divide 786 by 788, we get 0 and a remainder of 786.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 786 after subtracting 0 from 786.
Append the next digit (2) from the dividend to 786 and continue with: 7862 / 788

Let's proceed to step 4:
The number 788 fits into 7862 9 times, leaving a remainder of 770.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 7092 from 7862, we get 770.
Append the next digit (3) from the dividend to 770 and continue with: 7703 / 788

Let's proceed to step 5:
The number 788 fits into 7703 9 times, leaving a remainder of 611.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
If we take 7092 away from 7703, we end up with 611.
Append the next digit (5) from the dividend to 611 and continue with: 6115 / 788

Let's proceed to step 6:
If we divide 6115 by 788, we get 7 and a remainder of 599.
Write down 7 as next digit of the result. 
Result so far: 997.0
Deduct 5516 from 6115 and we're left with 599.
Bring next digit (7) of the dividend behind the 599 and repeat the process: 5997 / 788

On to step 7:
788 goes into 5997 7 times with a remainder of 481.
Record the quotient 7 as the next digit in the result. 
Result so far: 9977.0
If we take 5516 away from 5997, we end up with 481.
Grab the next digit (5) from the dividend, add it to 481, then carry on: 4815 / 788

Moving on to step 8:
788 goes into 4815 6 times with a remainder of 87.
The number 6 becomes the next digit in our result. 
Result so far: 99776.0
If we subtract 4728 from 4815, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Going ahead to step 9:
The number 788 fits into 870 1 times, leaving a remainder of 82.
Put 1 as the next digit of the answer. 
Result so far: 99776.1
Deduct 788 from 870 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 10:
The number 788 fits into 820 1 times, leaving a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 99776.11
The remainder is 32 after subtracting 788 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 99776.11, with a leftover of 0.032.
