We look at the division of 29661439 by 577 
The aim is to understand the frequency of 577 in 29661439.

Let's proceed to step 1:
2 divided by 577 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 577

Step 2:
29 divided by 577 is 0 with a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 29 after subtracting 0 from 29.
Take the next digit (6) from the dividend and append it to 29, then repeat: 296 / 577

Moving on to step 3:
The number 577 fits into 296 0 times, leaving a remainder of 296.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 296 leaves us with 296.
Take the next digit (6) from the dividend and append it to 296, then repeat: 2966 / 577

Step 4:
The number 577 fits into 2966 5 times, leaving a remainder of 81.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 2885 from 2966 and we're left with 81.
Append the next digit (1) from the dividend to 81 and continue with: 811 / 577

Step 5:
811 divided by 577 is 1 with a remainder of 234.
Record the quotient 1 as the next digit in the result. 
Result so far: 51.0
Deduct 577 from 811 and we're left with 234.
Append the next digit (4) from the dividend to 234 and continue with: 2344 / 577

On to step 6:
577 goes into 2344 4 times with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 514.0
The remainder is 36 after subtracting 2308 from 2344.
Grab the next digit (3) from the dividend, add it to 36, then carry on: 363 / 577

On to step 7:
363 divided by 577 is 0 with a remainder of 363.
Record the quotient 0 as the next digit in the result. 
Result so far: 5140.0
If we subtract 0 from 363, we get 363.
Bring next digit (9) of the dividend behind the 363 and repeat the process: 3639 / 577

Moving on to step 8:
577 goes into 3639 6 times with a remainder of 177.
Record the quotient 6 as the next digit in the result. 
Result so far: 51406.0
Subtract 3462 from 3639 to get 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

On to step 9:
If we divide 1770 by 577, we get 3 and a remainder of 39.
Write down 3 as next digit of the result. 
Result so far: 51406.3
Subtracting 1731 from 1770 leaves us 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.

Let's proceed to step 10:
The number 577 fits into 390 0 times, leaving a remainder of 390.
Put 0 as the next digit of the answer. 
Result so far: 51406.3
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.

Let's proceed to step 11:
If we divide 3900 by 577, we get 6 and a remainder of 438.
Put 6 as the next digit of the answer. 
Result so far: 51406.306
Subtracting 3462 from 3900 leaves us with 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Going ahead to step 12:
When dividing 4380 by 577, we get 7 with a remainder of 341.
The next digit of our result is 7. 
Result so far: 51406.3067
If we take 4039 away from 4380, we end up with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Advancing to step 13:
577 goes into 3410 5 times with a remainder of 525.
The number 5 becomes the next digit in our result. 
Result so far: 51406.30675
If we take 2885 away from 3410, we end up with 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Let's proceed to step 14:
If we divide 5250 by 577, we get 9 and a remainder of 57.
Put 9 as the next digit of the answer. 
Result so far: 51406.306759
If we take 5193 away from 5250, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 15:
577 can be fit into 570 0 times, resulting in a remainder of 570.
Record the quotient 0 as the next digit in the result. 
Result so far: 51406.306759
Subtracting 0 from 570 leaves us with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Going ahead to step 16:
When dividing 5700 by 577, we get 9 with a remainder of 507.
The number 9 becomes the next digit in our result. 
Result so far: 51406.30675909
Subtracting 5193 from 5700 leaves us with 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

The quotient of the division is 51406.30675909, and the remainder is 5.07e-07.
