126147 ÷ 89 
The aim is to understand the frequency of 89 in 126147.

Going ahead to step 1:
1 divided by 89 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 89

Step 2:
89 can be fit into 12 0 times, resulting in a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 89

Moving on to step 3:
89 can be fit into 126 1 times, resulting in a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 89 from 126 leaves us with 37.
Include the next digit (1) from the dividend after 37, then repeat: 371 / 89

Step 4:
If we divide 371 by 89, we get 4 and a remainder of 15.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we take 356 away from 371, we end up with 15.
Include the next digit (4) from the dividend after 15, then repeat: 154 / 89

Let's proceed to step 5:
If we divide 154 by 89, we get 1 and a remainder of 65.
Write down 1 as next digit of the result. 
Result so far: 141.0
If we take 89 away from 154, we end up with 65.
Fetch the next digit (7) from the dividend, attach it to 65 and continue: 657 / 89

Moving on to step 6:
When dividing 657 by 89, we get 7 with a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 1417.0
Deduct 623 from 657 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 7:
340 divided by 89 is 3 with a remainder of 73.
Put 3 as the next digit of the answer. 
Result so far: 1417.3
Subtracting 267 from 340 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 8:
730 divided by 89 is 8 with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 1417.38
Subtracting 712 from 730 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 9:
When dividing 180 by 89, we get 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 1417.382
If we take 178 away from 180, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 10:
89 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 1417.382
The remainder is 20 after subtracting 0 from 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:
If we divide 200 by 89, we get 2 and a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 1417.38202
Subtract 178 from 200 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 12:
The number 89 fits into 220 2 times, leaving a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 1417.382022
If we take 178 away from 220, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Our division results in 1417.382022 with a remaining 4.2e-06.
