65026221 ÷ 423 
The aim is to understand the frequency of 423 in 65026221.

Advancing to step 1:
6 divided by 423 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 423

Going ahead to step 2:
If we divide 65 by 423, we get 0 and a remainder of 65.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 65, we get 65.
Grab the next digit (0) from the dividend, add it to 65, then carry on: 650 / 423

Advancing to step 3:
When dividing 650 by 423, we get 1 with a remainder of 227.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 227 after subtracting 423 from 650.
Fetch the next digit (2) from the dividend, attach it to 227 and continue: 2272 / 423

Step 4:
When dividing 2272 by 423, we get 5 with a remainder of 157.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtract 2115 from 2272 to get 157.
Grab the next digit (6) from the dividend, add it to 157, then carry on: 1576 / 423

Step 5:
If we divide 1576 by 423, we get 3 and a remainder of 307.
Write down 3 as next digit of the result. 
Result so far: 153.0
Subtracting 1269 from 1576 leaves us with 307.
Bring next digit (2) of the dividend behind the 307 and repeat the process: 3072 / 423

Going ahead to step 6:
3072 divided by 423 is 7 with a remainder of 111.
Put 7 as the next digit of the answer. 
Result so far: 1537.0
Subtracting 2961 from 3072 leaves us with 111.
Append the next digit (2) from the dividend to 111 and continue with: 1112 / 423

Moving on to step 7:
423 can be fit into 1112 2 times, resulting in a remainder of 266.
Record the quotient 2 as the next digit in the result. 
Result so far: 15372.0
If we take 846 away from 1112, we end up with 266.
Include the next digit (1) from the dividend after 266, then repeat: 2661 / 423

Step 8:
When dividing 2661 by 423, we get 6 with a remainder of 123.
Write down 6 as next digit of the result. 
Result so far: 153726.0
Deduct 2538 from 2661 and we're left with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Going ahead to step 9:
The number 423 fits into 1230 2 times, leaving a remainder of 384.
Put 2 as the next digit of the answer. 
Result so far: 153726.2
The remainder is 384 after subtracting 846 from 1230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Advancing to step 10:
If we divide 3840 by 423, we get 9 and a remainder of 33.
Write down 9 as next digit of the result. 
Result so far: 153726.29
The remainder is 33 after subtracting 3807 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 11:
If we divide 330 by 423, we get 0 and a remainder of 330.
The number 0 becomes the next digit in our result. 
Result so far: 153726.29
Subtract 0 from 330 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

On to step 12:
3300 divided by 423 is 7 with a remainder of 339.
Use 7 as the next digit of our solution. 
Result so far: 153726.2907
The remainder is 339 after subtracting 2961 from 3300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Advancing to step 13:
423 goes into 3390 8 times with a remainder of 6.
The next digit of our result is 8. 
Result so far: 153726.29078
The remainder is 6 after subtracting 3384 from 3390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 14:
60 divided by 423 is 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 153726.29078
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 15:
If we divide 600 by 423, we get 1 and a remainder of 177.
Use 1 as the next digit of our solution. 
Result so far: 153726.2907801
If we take 423 away from 600, we end up with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Going ahead to step 16:
When dividing 1770 by 423, we get 4 with a remainder of 78.
Use 4 as the next digit of our solution. 
Result so far: 153726.29078014
If we take 1692 away from 1770, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

The final result is 153726.29078014 with a remainder of 7.8e-08.
