We look at the division of 78057221 by 594 
The aim is to understand the frequency of 594 in 78057221.

On to step 1:
594 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 594

Step 2:
78 divided by 594 is 0 with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Bring next digit (0) of the dividend behind the 78 and repeat the process: 780 / 594

Moving on to step 3:
When dividing 780 by 594, we get 1 with a remainder of 186.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 594 from 780 leaves us with 186.
Include the next digit (5) from the dividend after 186, then repeat: 1865 / 594

Step 4:
The number 594 fits into 1865 3 times, leaving a remainder of 83.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 1782 from 1865 to get 83.
Take the next digit (7) from the dividend and append it to 83, then repeat: 837 / 594

Going ahead to step 5:
594 goes into 837 1 times with a remainder of 243.
Write down 1 as next digit of the result. 
Result so far: 131.0
If we take 594 away from 837, we end up with 243.
Append the next digit (2) from the dividend to 243 and continue with: 2432 / 594

Let's proceed to step 6:
594 goes into 2432 4 times with a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 1314.0
If we subtract 2376 from 2432, we get 56.
Bring next digit (2) of the dividend behind the 56 and repeat the process: 562 / 594

On to step 7:
When dividing 562 by 594, we get 0 with a remainder of 562.
Record the quotient 0 as the next digit in the result. 
Result so far: 13140.0
The remainder is 562 after subtracting 0 from 562.
Include the next digit (1) from the dividend after 562, then repeat: 5621 / 594

Let's proceed to step 8:
The number 594 fits into 5621 9 times, leaving a remainder of 275.
Record the quotient 9 as the next digit in the result. 
Result so far: 131409.0
Deduct 5346 from 5621 and we're left with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

On to step 9:
594 goes into 2750 4 times with a remainder of 374.
The next digit of our result is 4. 
Result so far: 131409.4
Subtract 2376 from 2750 to get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

On to step 10:
3740 divided by 594 is 6 with a remainder of 176.
The number 6 becomes the next digit in our result. 
Result so far: 131409.46
If we subtract 3564 from 3740, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 11:
When dividing 1760 by 594, we get 2 with a remainder of 572.
Use 2 as the next digit of our solution. 
Result so far: 131409.462
Subtracting 1188 from 1760 leaves us with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Advancing to step 12:
When dividing 5720 by 594, we get 9 with a remainder of 374.
The next digit of our result is 9. 
Result so far: 131409.4629
Subtract 5346 from 5720 to get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Going ahead to step 13:
594 can be fit into 3740 6 times, resulting in a remainder of 176.
Record the quotient 6 as the next digit in the result. 
Result so far: 131409.46296
Subtract 3564 from 3740 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 14:
The number 594 fits into 1760 2 times, leaving a remainder of 572.
Record the quotient 2 as the next digit in the result. 
Result so far: 131409.462962
If we take 1188 away from 1760, we end up with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Going ahead to step 15:
The number 594 fits into 5720 9 times, leaving a remainder of 374.
Put 9 as the next digit of the answer. 
Result so far: 131409.4629629
Deduct 5346 from 5720 and we're left with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Step 16:
594 can be fit into 3740 6 times, resulting in a remainder of 176.
The number 6 becomes the next digit in our result. 
Result so far: 131409.46296296
Deduct 3564 from 3740 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

The final outcome is 131409.46296296, with a leftover of 1.76e-07.
