We divide 64545159 by 427
The aim is to understand the frequency of 427 in 64545159.

On to step 1:
If we divide 6 by 427, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 427

On to step 2:
427 can be fit into 64 0 times, resulting in a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Include the next digit (5) from the dividend after 64, then repeat: 645 / 427

Let's proceed to step 3:
The number 427 fits into 645 1 times, leaving a remainder of 218.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 427 from 645 leaves us with 218.
Fetch the next digit (4) from the dividend, attach it to 218 and continue: 2184 / 427

Going ahead to step 4:
The number 427 fits into 2184 5 times, leaving a remainder of 49.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Deduct 2135 from 2184 and we're left with 49.
Take the next digit (5) from the dividend and append it to 49, then repeat: 495 / 427

Moving on to step 5:
When dividing 495 by 427, we get 1 with a remainder of 68.
Write down 1 as next digit of the result. 
Result so far: 151.0
The remainder is 68 after subtracting 427 from 495.
Bring next digit (1) of the dividend behind the 68 and repeat the process: 681 / 427

Going ahead to step 6:
If we divide 681 by 427, we get 1 and a remainder of 254.
Record the quotient 1 as the next digit in the result. 
Result so far: 1511.0
If we subtract 427 from 681, we get 254.
Include the next digit (5) from the dividend after 254, then repeat: 2545 / 427

Advancing to step 7:
When dividing 2545 by 427, we get 5 with a remainder of 410.
Use 5 as the next digit of our solution. 
Result so far: 15115.0
Deduct 2135 from 2545 and we're left with 410.
Bring next digit (9) of the dividend behind the 410 and repeat the process: 4109 / 427

Moving on to step 8:
427 can be fit into 4109 9 times, resulting in a remainder of 266.
Use 9 as the next digit of our solution. 
Result so far: 151159.0
If we take 3843 away from 4109, we end up with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

On to step 9:
When dividing 2660 by 427, we get 6 with a remainder of 98.
Record the quotient 6 as the next digit in the result. 
Result so far: 151159.6
Subtract 2562 from 2660 to get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Moving on to step 10:
427 goes into 980 2 times with a remainder of 126.
Use 2 as the next digit of our solution. 
Result so far: 151159.62
If we subtract 854 from 980, we get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 11:
427 goes into 1260 2 times with a remainder of 406.
The number 2 becomes the next digit in our result. 
Result so far: 151159.622
Deduct 854 from 1260 and we're left with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

The final result is 151159.622 with a remainder of 0.0406.
