81950503 ÷ 340 
The aim is to understand the frequency of 340 in 81950503.

On to step 1:
If we divide 8 by 340, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 340

Going ahead to step 2:
When dividing 81 by 340, we get 0 with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Take the next digit (9) from the dividend and append it to 81, then repeat: 819 / 340

Step 3:
The number 340 fits into 819 2 times, leaving a remainder of 139.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 139 after subtracting 680 from 819.
Append the next digit (5) from the dividend to 139 and continue with: 1395 / 340

Advancing to step 4:
The number 340 fits into 1395 4 times, leaving a remainder of 35.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
Deduct 1360 from 1395 and we're left with 35.
Fetch the next digit (0) from the dividend, attach it to 35 and continue: 350 / 340

Advancing to step 5:
When dividing 350 by 340, we get 1 with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 241.0
Subtract 340 from 350 to get 10.
Grab the next digit (5) from the dividend, add it to 10, then carry on: 105 / 340

On to step 6:
If we divide 105 by 340, we get 0 and a remainder of 105.
Put 0 as the next digit of the answer. 
Result so far: 2410.0
If we take 0 away from 105, we end up with 105.
Fetch the next digit (0) from the dividend, attach it to 105 and continue: 1050 / 340

Going ahead to step 7:
1050 divided by 340 is 3 with a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 24103.0
The remainder is 30 after subtracting 1020 from 1050.
Fetch the next digit (3) from the dividend, attach it to 30 and continue: 303 / 340

Advancing to step 8:
340 goes into 303 0 times with a remainder of 303.
Record the quotient 0 as the next digit in the result. 
Result so far: 241030.0
If we subtract 0 from 303, we get 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Going ahead to step 9:
When dividing 3030 by 340, we get 8 with a remainder of 310.
Put 8 as the next digit of the answer. 
Result so far: 241030.8
Deduct 2720 from 3030 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Advancing to step 10:
340 can be fit into 3100 9 times, resulting in a remainder of 40.
The next digit of our result is 9. 
Result so far: 241030.89
If we subtract 3060 from 3100, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
340 can be fit into 400 1 times, resulting in a remainder of 60.
Write down 1 as next digit of the result. 
Result so far: 241030.891
Deduct 340 from 400 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 12:
The number 340 fits into 600 1 times, leaving a remainder of 260.
Put 1 as the next digit of the answer. 
Result so far: 241030.8911
Subtract 340 from 600 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

The final outcome is 241030.8911, with a leftover of 0.0026.
