18224318 ÷ 620 
The aim is to understand the frequency of 620 in 18224318.

Going ahead to step 1:
The number 620 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 620

Let's proceed to step 2:
620 goes into 18 0 times with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Fetch the next digit (2) from the dividend, attach it to 18 and continue: 182 / 620

Step 3:
620 can be fit into 182 0 times, resulting in a remainder of 182.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 182, we get 182.
Grab the next digit (2) from the dividend, add it to 182, then carry on: 1822 / 620

Advancing to step 4:
1822 divided by 620 is 2 with a remainder of 582.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 1240 from 1822 leaves us with 582.
Bring next digit (4) of the dividend behind the 582 and repeat the process: 5824 / 620

Let's proceed to step 5:
When dividing 5824 by 620, we get 9 with a remainder of 244.
Put 9 as the next digit of the answer. 
Result so far: 29.0
If we subtract 5580 from 5824, we get 244.
Take the next digit (3) from the dividend and append it to 244, then repeat: 2443 / 620

Advancing to step 6:
2443 divided by 620 is 3 with a remainder of 583.
Put 3 as the next digit of the answer. 
Result so far: 293.0
Subtracting 1860 from 2443 leaves us with 583.
Fetch the next digit (1) from the dividend, attach it to 583 and continue: 5831 / 620

Going ahead to step 7:
620 goes into 5831 9 times with a remainder of 251.
Write down 9 as next digit of the result. 
Result so far: 2939.0
Subtract 5580 from 5831 to get 251.
Grab the next digit (8) from the dividend, add it to 251, then carry on: 2518 / 620

Step 8:
The number 620 fits into 2518 4 times, leaving a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 29394.0
If we subtract 2480 from 2518, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 9:
380 divided by 620 is 0 with a remainder of 380.
The next digit of our result is 0. 
Result so far: 29394.0
Subtracting 0 from 380 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 10:
620 goes into 3800 6 times with a remainder of 80.
Write down 6 as next digit of the result. 
Result so far: 29394.06
Subtract 3720 from 3800 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 11:
When dividing 800 by 620, we get 1 with a remainder of 180.
Put 1 as the next digit of the answer. 
Result so far: 29394.061
Subtracting 620 from 800 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 12:
The number 620 fits into 1800 2 times, leaving a remainder of 560.
The next digit of our result is 2. 
Result so far: 29394.0612
Subtract 1240 from 1800 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 13:
620 can be fit into 5600 9 times, resulting in a remainder of 20.
The next digit of our result is 9. 
Result so far: 29394.06129
Subtract 5580 from 5600 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 14:
620 goes into 200 0 times with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 29394.06129
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 15:
When dividing 2000 by 620, we get 3 with a remainder of 140.
Use 3 as the next digit of our solution. 
Result so far: 29394.0612903
Deduct 1860 from 2000 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 16:
1400 divided by 620 is 2 with a remainder of 160.
Write down 2 as next digit of the result. 
Result so far: 29394.06129032
Deduct 1240 from 1400 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final outcome is 29394.06129032, with a leftover of 1.6e-07.
