We divide 43144559 by 60
The aim is to understand the frequency of 60 in 43144559.

Moving on to step 1:
When dividing 4 by 60, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 60

Let's proceed to step 2:
The number 60 fits into 43 0 times, leaving a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Fetch the next digit (1) from the dividend, attach it to 43 and continue: 431 / 60

Step 3:
60 can be fit into 431 7 times, resulting in a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 420 away from 431, we end up with 11.
Fetch the next digit (4) from the dividend, attach it to 11 and continue: 114 / 60

Advancing to step 4:
The number 60 fits into 114 1 times, leaving a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 71.0
Subtracting 60 from 114 leaves us with 54.
Fetch the next digit (4) from the dividend, attach it to 54 and continue: 544 / 60

Moving on to step 5:
If we divide 544 by 60, we get 9 and a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 719.0
Deduct 540 from 544 and we're left with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 60

Advancing to step 6:
The number 60 fits into 45 0 times, leaving a remainder of 45.
The next digit of our result is 0. 
Result so far: 7190.0
Subtract 0 from 45 to get 45.
Bring next digit (5) of the dividend behind the 45 and repeat the process: 455 / 60

Step 7:
60 can be fit into 455 7 times, resulting in a remainder of 35.
Record the quotient 7 as the next digit in the result. 
Result so far: 71907.0
If we subtract 420 from 455, we get 35.
Grab the next digit (9) from the dividend, add it to 35, then carry on: 359 / 60

On to step 8:
The number 60 fits into 359 5 times, leaving a remainder of 59.
The next digit of our result is 5. 
Result so far: 719075.0
If we take 300 away from 359, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 9:
60 goes into 590 9 times with a remainder of 50.
Write down 9 as next digit of the result. 
Result so far: 719075.9
The remainder is 50 after subtracting 540 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
The number 60 fits into 500 8 times, leaving a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 719075.98
Subtracting 480 from 500 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
The number 60 fits into 200 3 times, leaving a remainder of 20.
Put 3 as the next digit of the answer. 
Result so far: 719075.983
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 12:
60 can be fit into 200 3 times, resulting in a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 719075.9833
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 719075.9833 and a remainder of 0.0002.
