We look at the division of 68779157 by 577 
The aim is to understand the frequency of 577 in 68779157.

On to step 1:
6 divided by 577 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 577

Step 2:
The number 577 fits into 68 0 times, leaving a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Grab the next digit (7) from the dividend, add it to 68, then carry on: 687 / 577

Moving on to step 3:
The number 577 fits into 687 1 times, leaving a remainder of 110.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 577 from 687 to get 110.
Fetch the next digit (7) from the dividend, attach it to 110 and continue: 1107 / 577

On to step 4:
If we divide 1107 by 577, we get 1 and a remainder of 530.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtracting 577 from 1107 leaves us with 530.
Append the next digit (9) from the dividend to 530 and continue with: 5309 / 577

Let's proceed to step 5:
If we divide 5309 by 577, we get 9 and a remainder of 116.
Record the quotient 9 as the next digit in the result. 
Result so far: 119.0
If we subtract 5193 from 5309, we get 116.
Bring next digit (1) of the dividend behind the 116 and repeat the process: 1161 / 577

On to step 6:
1161 divided by 577 is 2 with a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 1192.0
Deduct 1154 from 1161 and we're left with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 577

Let's proceed to step 7:
75 divided by 577 is 0 with a remainder of 75.
Put 0 as the next digit of the answer. 
Result so far: 11920.0
If we subtract 0 from 75, we get 75.
Take the next digit (7) from the dividend and append it to 75, then repeat: 757 / 577

Step 8:
577 can be fit into 757 1 times, resulting in a remainder of 180.
The next digit of our result is 1. 
Result so far: 119201.0
Deduct 577 from 757 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 9:
When dividing 1800 by 577, we get 3 with a remainder of 69.
Put 3 as the next digit of the answer. 
Result so far: 119201.3
Deduct 1731 from 1800 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 10:
577 can be fit into 690 1 times, resulting in a remainder of 113.
The number 1 becomes the next digit in our result. 
Result so far: 119201.31
Subtract 577 from 690 to get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Step 11:
577 goes into 1130 1 times with a remainder of 553.
Write down 1 as next digit of the result. 
Result so far: 119201.311
Deduct 577 from 1130 and we're left with 553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

The final outcome is 119201.311, with a leftover of 0.0553.
