We're dividing 90890012 by 724 
The aim is to understand the frequency of 724 in 90890012.

Let's proceed to step 1:
724 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 724

Moving on to step 2:
90 divided by 724 is 0 with a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Fetch the next digit (8) from the dividend, attach it to 90 and continue: 908 / 724

Moving on to step 3:
When dividing 908 by 724, we get 1 with a remainder of 184.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 724 from 908 and we're left with 184.
Grab the next digit (9) from the dividend, add it to 184, then carry on: 1849 / 724

On to step 4:
1849 divided by 724 is 2 with a remainder of 401.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 1448 from 1849 leaves us with 401.
Append the next digit (0) from the dividend to 401 and continue with: 4010 / 724

Advancing to step 5:
724 can be fit into 4010 5 times, resulting in a remainder of 390.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
If we take 3620 away from 4010, we end up with 390.
Fetch the next digit (0) from the dividend, attach it to 390 and continue: 3900 / 724

On to step 6:
When dividing 3900 by 724, we get 5 with a remainder of 280.
Record the quotient 5 as the next digit in the result. 
Result so far: 1255.0
If we subtract 3620 from 3900, we get 280.
Take the next digit (1) from the dividend and append it to 280, then repeat: 2801 / 724

On to step 7:
If we divide 2801 by 724, we get 3 and a remainder of 629.
Put 3 as the next digit of the answer. 
Result so far: 12553.0
If we subtract 2172 from 2801, we get 629.
Include the next digit (2) from the dividend after 629, then repeat: 6292 / 724

On to step 8:
724 can be fit into 6292 8 times, resulting in a remainder of 500.
Use 8 as the next digit of our solution. 
Result so far: 125538.0
If we subtract 5792 from 6292, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Going ahead to step 9:
If we divide 5000 by 724, we get 6 and a remainder of 656.
Write down 6 as next digit of the result. 
Result so far: 125538.6
If we subtract 4344 from 5000, we get 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Moving on to step 10:
724 goes into 6560 9 times with a remainder of 44.
Record the quotient 9 as the next digit in the result. 
Result so far: 125538.69
If we subtract 6516 from 6560, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 11:
724 can be fit into 440 0 times, resulting in a remainder of 440.
The next digit of our result is 0. 
Result so far: 125538.69
Subtracting 0 from 440 leaves us with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 12:
When dividing 4400 by 724, we get 6 with a remainder of 56.
Use 6 as the next digit of our solution. 
Result so far: 125538.6906
Subtracting 4344 from 4400 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 13:
When dividing 560 by 724, we get 0 with a remainder of 560.
The number 0 becomes the next digit in our result. 
Result so far: 125538.6906
Subtracting 0 from 560 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Moving on to step 14:
5600 divided by 724 is 7 with a remainder of 532.
Write down 7 as next digit of the result. 
Result so far: 125538.690607
The remainder is 532 after subtracting 5068 from 5600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Going ahead to step 15:
5320 divided by 724 is 7 with a remainder of 252.
Put 7 as the next digit of the answer. 
Result so far: 125538.6906077
Subtracting 5068 from 5320 leaves us with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

The final result is 125538.6906077 with a remainder of 2.52e-06.
