Let's divide 214678 by 90
The aim is to understand the frequency of 90 in 214678.

Advancing to step 1:
The number 90 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 90

Moving on to step 2:
90 goes into 21 0 times with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Fetch the next digit (4) from the dividend, attach it to 21 and continue: 214 / 90

Moving on to step 3:
90 can be fit into 214 2 times, resulting in a remainder of 34.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 34 after subtracting 180 from 214.
Grab the next digit (6) from the dividend, add it to 34, then carry on: 346 / 90

Let's proceed to step 4:
90 can be fit into 346 3 times, resulting in a remainder of 76.
Write down 3 as next digit of the result. 
Result so far: 23.0
Subtracting 270 from 346 leaves us with 76.
Grab the next digit (7) from the dividend, add it to 76, then carry on: 767 / 90

Going ahead to step 5:
90 goes into 767 8 times with a remainder of 47.
The number 8 becomes the next digit in our result. 
Result so far: 238.0
If we take 720 away from 767, we end up with 47.
Bring next digit (8) of the dividend behind the 47 and repeat the process: 478 / 90

Advancing to step 6:
If we divide 478 by 90, we get 5 and a remainder of 28.
The next digit of our result is 5. 
Result so far: 2385.0
Subtract 450 from 478 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 7:
The number 90 fits into 280 3 times, leaving a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 2385.3
Subtracting 270 from 280 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
When dividing 100 by 90, we get 1 with a remainder of 10.
The next digit of our result is 1. 
Result so far: 2385.31
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
90 can be fit into 100 1 times, resulting in a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 2385.311
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 2385.311 with a balance of 0.001.
