We're dividing 49720559 by 574 
The aim is to understand the frequency of 574 in 49720559.

Advancing to step 1:
The number 574 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 574

On to step 2:
When dividing 49 by 574, we get 0 with a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 49, we get 49.
Fetch the next digit (7) from the dividend, attach it to 49 and continue: 497 / 574

Advancing to step 3:
The number 574 fits into 497 0 times, leaving a remainder of 497.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 497 to get 497.
Append the next digit (2) from the dividend to 497 and continue with: 4972 / 574

Let's proceed to step 4:
If we divide 4972 by 574, we get 8 and a remainder of 380.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 4592 from 4972, we get 380.
Take the next digit (0) from the dividend and append it to 380, then repeat: 3800 / 574

Going ahead to step 5:
574 goes into 3800 6 times with a remainder of 356.
Write down 6 as next digit of the result. 
Result so far: 86.0
Subtract 3444 from 3800 to get 356.
Append the next digit (5) from the dividend to 356 and continue with: 3565 / 574

Going ahead to step 6:
When dividing 3565 by 574, we get 6 with a remainder of 121.
Use 6 as the next digit of our solution. 
Result so far: 866.0
Subtract 3444 from 3565 to get 121.
Grab the next digit (5) from the dividend, add it to 121, then carry on: 1215 / 574

Going ahead to step 7:
When dividing 1215 by 574, we get 2 with a remainder of 67.
Record the quotient 2 as the next digit in the result. 
Result so far: 8662.0
The remainder is 67 after subtracting 1148 from 1215.
Fetch the next digit (9) from the dividend, attach it to 67 and continue: 679 / 574

Step 8:
When dividing 679 by 574, we get 1 with a remainder of 105.
The number 1 becomes the next digit in our result. 
Result so far: 86621.0
Subtract 574 from 679 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

On to step 9:
1050 divided by 574 is 1 with a remainder of 476.
Put 1 as the next digit of the answer. 
Result so far: 86621.1
If we take 574 away from 1050, we end up with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Advancing to step 10:
574 goes into 4760 8 times with a remainder of 168.
The next digit of our result is 8. 
Result so far: 86621.18
If we take 4592 away from 4760, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

On to step 11:
574 goes into 1680 2 times with a remainder of 532.
Put 2 as the next digit of the answer. 
Result so far: 86621.182
The remainder is 532 after subtracting 1148 from 1680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Advancing to step 12:
If we divide 5320 by 574, we get 9 and a remainder of 154.
Write down 9 as next digit of the result. 
Result so far: 86621.1829
The remainder is 154 after subtracting 5166 from 5320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Step 13:
1540 divided by 574 is 2 with a remainder of 392.
Record the quotient 2 as the next digit in the result. 
Result so far: 86621.18292
If we take 1148 away from 1540, we end up with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Going ahead to step 14:
574 can be fit into 3920 6 times, resulting in a remainder of 476.
Write down 6 as next digit of the result. 
Result so far: 86621.182926
Subtracting 3444 from 3920 leaves us with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Let's proceed to step 15:
574 can be fit into 4760 8 times, resulting in a remainder of 168.
Use 8 as the next digit of our solution. 
Result so far: 86621.1829268
Deduct 4592 from 4760 and we're left with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Moving on to step 16:
If we divide 1680 by 574, we get 2 and a remainder of 532.
Record the quotient 2 as the next digit in the result. 
Result so far: 86621.18292682
Deduct 1148 from 1680 and we're left with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

The final result is 86621.18292682 with a remainder of 5.32e-07.
