We divide 784224 by 89
The aim is to understand the frequency of 89 in 784224.

On to step 1:
When dividing 7 by 89, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 89

Advancing to step 2:
If we divide 78 by 89, we get 0 and a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Grab the next digit (4) from the dividend, add it to 78, then carry on: 784 / 89

Step 3:
When dividing 784 by 89, we get 8 with a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 712 from 784 leaves us with 72.
Bring next digit (2) of the dividend behind the 72 and repeat the process: 722 / 89

Step 4:
722 divided by 89 is 8 with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 88.0
Subtract 712 from 722 to get 10.
Take the next digit (2) from the dividend and append it to 10, then repeat: 102 / 89

Advancing to step 5:
89 goes into 102 1 times with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 881.0
If we take 89 away from 102, we end up with 13.
Include the next digit (4) from the dividend after 13, then repeat: 134 / 89

Let's proceed to step 6:
If we divide 134 by 89, we get 1 and a remainder of 45.
The next digit of our result is 1. 
Result so far: 8811.0
Subtracting 89 from 134 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 7:
89 goes into 450 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 8811.5
If we take 445 away from 450, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 8:
When dividing 50 by 89, we get 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 8811.5
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
When dividing 500 by 89, we get 5 with a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 8811.505
If we take 445 away from 500, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 10:
89 goes into 550 6 times with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 8811.5056
Subtract 534 from 550 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
When dividing 160 by 89, we get 1 with a remainder of 71.
The number 1 becomes the next digit in our result. 
Result so far: 8811.50561
Subtracting 89 from 160 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 12:
If we divide 710 by 89, we get 7 and a remainder of 87.
Write down 7 as next digit of the result. 
Result so far: 8811.505617
Subtracting 623 from 710 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Moving on to step 13:
The number 89 fits into 870 9 times, leaving a remainder of 69.
Record the quotient 9 as the next digit in the result. 
Result so far: 8811.5056179
Deduct 801 from 870 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.

On to step 14:
The number 89 fits into 690 7 times, leaving a remainder of 67.
Put 7 as the next digit of the answer. 
Result so far: 8811.50561797
Deduct 623 from 690 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

The final outcome is 8811.50561797, with a leftover of 6.7e-08.
