We're dividing 14001880 by 843 
The aim is to understand the frequency of 843 in 14001880.

Step 1:
When dividing 1 by 843, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 843

Step 2:
The number 843 fits into 14 0 times, leaving a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 843

On to step 3:
The number 843 fits into 140 0 times, leaving a remainder of 140.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 140, we get 140.
Include the next digit (0) from the dividend after 140, then repeat: 1400 / 843

Step 4:
If we divide 1400 by 843, we get 1 and a remainder of 557.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 843 from 1400 and we're left with 557.
Fetch the next digit (1) from the dividend, attach it to 557 and continue: 5571 / 843

Let's proceed to step 5:
When dividing 5571 by 843, we get 6 with a remainder of 513.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtract 5058 from 5571 to get 513.
Grab the next digit (8) from the dividend, add it to 513, then carry on: 5138 / 843

Moving on to step 6:
843 can be fit into 5138 6 times, resulting in a remainder of 80.
Write down 6 as next digit of the result. 
Result so far: 166.0
If we subtract 5058 from 5138, we get 80.
Grab the next digit (8) from the dividend, add it to 80, then carry on: 808 / 843

On to step 7:
843 goes into 808 0 times with a remainder of 808.
Put 0 as the next digit of the answer. 
Result so far: 1660.0
Deduct 0 from 808 and we're left with 808.
Take the next digit (0) from the dividend and append it to 808, then repeat: 8080 / 843

Moving on to step 8:
If we divide 8080 by 843, we get 9 and a remainder of 493.
The number 9 becomes the next digit in our result. 
Result so far: 16609.0
The remainder is 493 after subtracting 7587 from 8080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

Step 9:
843 can be fit into 4930 5 times, resulting in a remainder of 715.
Put 5 as the next digit of the answer. 
Result so far: 16609.5
Subtract 4215 from 4930 to get 715.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7150, and continue the process.

Step 10:
7150 divided by 843 is 8 with a remainder of 406.
Use 8 as the next digit of our solution. 
Result so far: 16609.58
The remainder is 406 after subtracting 6744 from 7150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Going ahead to step 11:
4060 divided by 843 is 4 with a remainder of 688.
Write down 4 as next digit of the result. 
Result so far: 16609.584
Deduct 3372 from 4060 and we're left with 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

On to step 12:
843 goes into 6880 8 times with a remainder of 136.
The next digit of our result is 8. 
Result so far: 16609.5848
The remainder is 136 after subtracting 6744 from 6880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

On to step 13:
The number 843 fits into 1360 1 times, leaving a remainder of 517.
The next digit of our result is 1. 
Result so far: 16609.58481
Subtract 843 from 1360 to get 517.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5170, and continue the process.

Let's proceed to step 14:
5170 divided by 843 is 6 with a remainder of 112.
Use 6 as the next digit of our solution. 
Result so far: 16609.584816
Subtracting 5058 from 5170 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 15:
1120 divided by 843 is 1 with a remainder of 277.
Record the quotient 1 as the next digit in the result. 
Result so far: 16609.5848161
The remainder is 277 after subtracting 843 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Step 16:
The number 843 fits into 2770 3 times, leaving a remainder of 241.
The number 3 becomes the next digit in our result. 
Result so far: 16609.58481613
Subtracting 2529 from 2770 leaves us with 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

The final result is 16609.58481613 with a remainder of 2.41e-07.
