98519998 ÷ 574 
The aim is to understand the frequency of 574 in 98519998.

Step 1:
The number 574 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 574

Step 2:
If we divide 98 by 574, we get 0 and a remainder of 98.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 98 leaves us with 98.
Include the next digit (5) from the dividend after 98, then repeat: 985 / 574

Moving on to step 3:
The number 574 fits into 985 1 times, leaving a remainder of 411.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 411 after subtracting 574 from 985.
Take the next digit (1) from the dividend and append it to 411, then repeat: 4111 / 574

Let's proceed to step 4:
When dividing 4111 by 574, we get 7 with a remainder of 93.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Deduct 4018 from 4111 and we're left with 93.
Grab the next digit (9) from the dividend, add it to 93, then carry on: 939 / 574

On to step 5:
574 can be fit into 939 1 times, resulting in a remainder of 365.
Write down 1 as next digit of the result. 
Result so far: 171.0
Subtracting 574 from 939 leaves us with 365.
Fetch the next digit (9) from the dividend, attach it to 365 and continue: 3659 / 574

On to step 6:
If we divide 3659 by 574, we get 6 and a remainder of 215.
Write down 6 as next digit of the result. 
Result so far: 1716.0
Subtract 3444 from 3659 to get 215.
Include the next digit (9) from the dividend after 215, then repeat: 2159 / 574

Advancing to step 7:
If we divide 2159 by 574, we get 3 and a remainder of 437.
Record the quotient 3 as the next digit in the result. 
Result so far: 17163.0
Subtract 1722 from 2159 to get 437.
Include the next digit (8) from the dividend after 437, then repeat: 4378 / 574

Moving on to step 8:
The number 574 fits into 4378 7 times, leaving a remainder of 360.
The number 7 becomes the next digit in our result. 
Result so far: 171637.0
If we subtract 4018 from 4378, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 9:
574 goes into 3600 6 times with a remainder of 156.
The next digit of our result is 6. 
Result so far: 171637.6
If we subtract 3444 from 3600, we get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Let's proceed to step 10:
The number 574 fits into 1560 2 times, leaving a remainder of 412.
Write down 2 as next digit of the result. 
Result so far: 171637.62
If we take 1148 away from 1560, we end up with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

On to step 11:
When dividing 4120 by 574, we get 7 with a remainder of 102.
Put 7 as the next digit of the answer. 
Result so far: 171637.627
Deduct 4018 from 4120 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 12:
The number 574 fits into 1020 1 times, leaving a remainder of 446.
Write down 1 as next digit of the result. 
Result so far: 171637.6271
If we take 574 away from 1020, we end up with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Going ahead to step 13:
4460 divided by 574 is 7 with a remainder of 442.
Write down 7 as next digit of the result. 
Result so far: 171637.62717
Deduct 4018 from 4460 and we're left with 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Moving on to step 14:
The number 574 fits into 4420 7 times, leaving a remainder of 402.
Record the quotient 7 as the next digit in the result. 
Result so far: 171637.627177
If we subtract 4018 from 4420, we get 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

The final outcome is 171637.627177, with a leftover of 4.02e-05.
