We divide 60784379 by 421
The aim is to understand the frequency of 421 in 60784379.

Step 1:
When dividing 6 by 421, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 421

Going ahead to step 2:
60 divided by 421 is 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 60 to get 60.
Include the next digit (7) from the dividend after 60, then repeat: 607 / 421

On to step 3:
607 divided by 421 is 1 with a remainder of 186.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 186 after subtracting 421 from 607.
Include the next digit (8) from the dividend after 186, then repeat: 1868 / 421

Let's proceed to step 4:
When dividing 1868 by 421, we get 4 with a remainder of 184.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtracting 1684 from 1868 leaves us with 184.
Take the next digit (4) from the dividend and append it to 184, then repeat: 1844 / 421

Moving on to step 5:
421 goes into 1844 4 times with a remainder of 160.
Record the quotient 4 as the next digit in the result. 
Result so far: 144.0
The remainder is 160 after subtracting 1684 from 1844.
Fetch the next digit (3) from the dividend, attach it to 160 and continue: 1603 / 421

Advancing to step 6:
If we divide 1603 by 421, we get 3 and a remainder of 340.
Use 3 as the next digit of our solution. 
Result so far: 1443.0
If we subtract 1263 from 1603, we get 340.
Append the next digit (7) from the dividend to 340 and continue with: 3407 / 421

Going ahead to step 7:
When dividing 3407 by 421, we get 8 with a remainder of 39.
Record the quotient 8 as the next digit in the result. 
Result so far: 14438.0
The remainder is 39 after subtracting 3368 from 3407.
Include the next digit (9) from the dividend after 39, then repeat: 399 / 421

On to step 8:
If we divide 399 by 421, we get 0 and a remainder of 399.
The next digit of our result is 0. 
Result so far: 144380.0
If we take 0 away from 399, we end up with 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

Moving on to step 9:
If we divide 3990 by 421, we get 9 and a remainder of 201.
Record the quotient 9 as the next digit in the result. 
Result so far: 144380.9
The remainder is 201 after subtracting 3789 from 3990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Advancing to step 10:
If we divide 2010 by 421, we get 4 and a remainder of 326.
The next digit of our result is 4. 
Result so far: 144380.94
Subtract 1684 from 2010 to get 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Let's proceed to step 11:
When dividing 3260 by 421, we get 7 with a remainder of 313.
The number 7 becomes the next digit in our result. 
Result so far: 144380.947
If we subtract 2947 from 3260, we get 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Step 12:
When dividing 3130 by 421, we get 7 with a remainder of 183.
Use 7 as the next digit of our solution. 
Result so far: 144380.9477
If we subtract 2947 from 3130, we get 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

In conclusion, the division gives 144380.9477 with a balance of 0.00183.
