Let's divide 89768236 by 421
The aim is to understand the frequency of 421 in 89768236.

Going ahead to step 1:
The number 421 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 421

Let's proceed to step 2:
89 divided by 421 is 0 with a remainder of 89.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 89 and we're left with 89.
Append the next digit (7) from the dividend to 89 and continue with: 897 / 421

On to step 3:
The number 421 fits into 897 2 times, leaving a remainder of 55.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 842 from 897 leaves us with 55.
Include the next digit (6) from the dividend after 55, then repeat: 556 / 421

Advancing to step 4:
The number 421 fits into 556 1 times, leaving a remainder of 135.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Subtract 421 from 556 to get 135.
Grab the next digit (8) from the dividend, add it to 135, then carry on: 1358 / 421

Let's proceed to step 5:
1358 divided by 421 is 3 with a remainder of 95.
Use 3 as the next digit of our solution. 
Result so far: 213.0
The remainder is 95 after subtracting 1263 from 1358.
Append the next digit (2) from the dividend to 95 and continue with: 952 / 421

Advancing to step 6:
If we divide 952 by 421, we get 2 and a remainder of 110.
Use 2 as the next digit of our solution. 
Result so far: 2132.0
Subtracting 842 from 952 leaves us with 110.
Bring next digit (3) of the dividend behind the 110 and repeat the process: 1103 / 421

Step 7:
421 goes into 1103 2 times with a remainder of 261.
Write down 2 as next digit of the result. 
Result so far: 21322.0
Deduct 842 from 1103 and we're left with 261.
Include the next digit (6) from the dividend after 261, then repeat: 2616 / 421

On to step 8:
2616 divided by 421 is 6 with a remainder of 90.
The number 6 becomes the next digit in our result. 
Result so far: 213226.0
If we take 2526 away from 2616, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 9:
421 goes into 900 2 times with a remainder of 58.
The next digit of our result is 2. 
Result so far: 213226.2
The remainder is 58 after subtracting 842 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 10:
580 divided by 421 is 1 with a remainder of 159.
The number 1 becomes the next digit in our result. 
Result so far: 213226.21
If we subtract 421 from 580, we get 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

On to step 11:
1590 divided by 421 is 3 with a remainder of 327.
Record the quotient 3 as the next digit in the result. 
Result so far: 213226.213
If we take 1263 away from 1590, we end up with 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

On to step 12:
When dividing 3270 by 421, we get 7 with a remainder of 323.
The number 7 becomes the next digit in our result. 
Result so far: 213226.2137
If we subtract 2947 from 3270, we get 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

On to step 13:
When dividing 3230 by 421, we get 7 with a remainder of 283.
Use 7 as the next digit of our solution. 
Result so far: 213226.21377
Subtracting 2947 from 3230 leaves us with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

In conclusion, the division gives 213226.21377 with a balance of 0.000283.
