We divide 50018749 by 620
The aim is to understand the frequency of 620 in 50018749.

Advancing to step 1:
When dividing 5 by 620, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 620

Advancing to step 2:
The number 620 fits into 50 0 times, leaving a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 50, we get 50.
Bring next digit (0) of the dividend behind the 50 and repeat the process: 500 / 620

Step 3:
When dividing 500 by 620, we get 0 with a remainder of 500.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 500 after subtracting 0 from 500.
Include the next digit (1) from the dividend after 500, then repeat: 5001 / 620

On to step 4:
The number 620 fits into 5001 8 times, leaving a remainder of 41.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 4960 from 5001 and we're left with 41.
Append the next digit (8) from the dividend to 41 and continue with: 418 / 620

Going ahead to step 5:
620 can be fit into 418 0 times, resulting in a remainder of 418.
Write down 0 as next digit of the result. 
Result so far: 80.0
Subtracting 0 from 418 leaves us with 418.
Grab the next digit (7) from the dividend, add it to 418, then carry on: 4187 / 620

Advancing to step 6:
620 can be fit into 4187 6 times, resulting in a remainder of 467.
Write down 6 as next digit of the result. 
Result so far: 806.0
Subtract 3720 from 4187 to get 467.
Grab the next digit (4) from the dividend, add it to 467, then carry on: 4674 / 620

Moving on to step 7:
When dividing 4674 by 620, we get 7 with a remainder of 334.
The number 7 becomes the next digit in our result. 
Result so far: 8067.0
If we subtract 4340 from 4674, we get 334.
Bring next digit (9) of the dividend behind the 334 and repeat the process: 3349 / 620

Step 8:
620 can be fit into 3349 5 times, resulting in a remainder of 249.
Record the quotient 5 as the next digit in the result. 
Result so far: 80675.0
Subtracting 3100 from 3349 leaves us with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Moving on to step 9:
2490 divided by 620 is 4 with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 80675.4
Subtract 2480 from 2490 to 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.

Step 10:
620 can be fit into 100 0 times, resulting in a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 80675.4
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 11:
When dividing 1000 by 620, we get 1 with a remainder of 380.
The next digit of our result is 1. 
Result so far: 80675.401
The remainder is 380 after subtracting 620 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 12:
620 goes into 3800 6 times with a remainder of 80.
Record the quotient 6 as the next digit in the result. 
Result so far: 80675.4016
If we take 3720 away from 3800, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 13:
620 can be fit into 800 1 times, resulting in a remainder of 180.
Put 1 as the next digit of the answer. 
Result so far: 80675.40161
If we take 620 away from 800, we end up 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.

Going ahead to step 14:
620 can be fit into 1800 2 times, resulting in a remainder of 560.
The next digit of our result is 2. 
Result so far: 80675.401612
If we take 1240 away from 1800, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Moving on to step 15:
620 can be fit into 5600 9 times, resulting in a remainder of 20.
Record the quotient 9 as the next digit in the result. 
Result so far: 80675.4016129
If we take 5580 away from 5600, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 16:
200 divided by 620 is 0 with a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 80675.4016129
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

In conclusion, the division gives 80675.4016129 with a balance of 2e-07.
