981691 divided by 43 
The aim is to understand the frequency of 43 in 981691.

Step 1:
If we divide 9 by 43, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 43

Advancing to step 2:
The number 43 fits into 98 2 times, leaving a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 86 from 98 leaves us with 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 43

Advancing to step 3:
The number 43 fits into 121 2 times, leaving a remainder of 35.
Use 2 as the next digit of our solution. 
Result so far: 22.0
Deduct 86 from 121 and we're left with 35.
Bring next digit (6) of the dividend behind the 35 and repeat the process: 356 / 43

On to step 4:
If we divide 356 by 43, we get 8 and a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 228.0
The remainder is 12 after subtracting 344 from 356.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 43

Advancing to step 5:
When dividing 129 by 43, we get 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 2283.0
Subtracting 129 from 129 leaves us with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 43

Let's proceed to step 6:
The number 43 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 22830.0
Subtracting 0 from 1 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
When dividing 10 by 43, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 22830.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
The number 43 fits into 100 2 times, leaving a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 22830.02
Deduct 86 from 100 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 9:
140 divided by 43 is 3 with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 22830.023
If we subtract 129 from 140, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 10:
The number 43 fits into 110 2 times, leaving a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 22830.0232
Subtract 86 from 110 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 11:
If we divide 240 by 43, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 22830.02325
The remainder is 25 after subtracting 215 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 12:
43 goes into 250 5 times with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 22830.023255
Deduct 215 from 250 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

After the division, we end up with 22830.023255 and a remainder of 3.5e-06.
