We divide 65352702 by 621
The aim is to understand the frequency of 621 in 65352702.

Moving on to step 1:
6 divided by 621 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 621

Let's proceed to step 2:
When dividing 65 by 621, we get 0 with a remainder of 65.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 65, we get 65.
Append the next digit (3) from the dividend to 65 and continue with: 653 / 621

Moving on to step 3:
When dividing 653 by 621, we get 1 with a remainder of 32.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 32 after subtracting 621 from 653.
Include the next digit (5) from the dividend after 32, then repeat: 325 / 621

Let's proceed to step 4:
When dividing 325 by 621, we get 0 with a remainder of 325.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 325, we get 325.
Grab the next digit (2) from the dividend, add it to 325, then carry on: 3252 / 621

On to step 5:
621 goes into 3252 5 times with a remainder of 147.
The next digit of our result is 5. 
Result so far: 105.0
Deduct 3105 from 3252 and we're left with 147.
Bring next digit (7) of the dividend behind the 147 and repeat the process: 1477 / 621

Advancing to step 6:
621 goes into 1477 2 times with a remainder of 235.
The next digit of our result is 2. 
Result so far: 1052.0
Subtracting 1242 from 1477 leaves us with 235.
Take the next digit (0) from the dividend and append it to 235, then repeat: 2350 / 621

Advancing to step 7:
2350 divided by 621 is 3 with a remainder of 487.
Put 3 as the next digit of the answer. 
Result so far: 10523.0
If we subtract 1863 from 2350, we get 487.
Include the next digit (2) from the dividend after 487, then repeat: 4872 / 621

Step 8:
The number 621 fits into 4872 7 times, leaving a remainder of 525.
The next digit of our result is 7. 
Result so far: 105237.0
If we take 4347 away from 4872, we end up with 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Going ahead to step 9:
If we divide 5250 by 621, we get 8 and a remainder of 282.
Record the quotient 8 as the next digit in the result. 
Result so far: 105237.8
Subtract 4968 from 5250 to get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Advancing to step 10:
The number 621 fits into 2820 4 times, leaving a remainder of 336.
The number 4 becomes the next digit in our result. 
Result so far: 105237.84
The remainder is 336 after subtracting 2484 from 2820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Going ahead to step 11:
621 goes into 3360 5 times with a remainder of 255.
Record the quotient 5 as the next digit in the result. 
Result so far: 105237.845
Deduct 3105 from 3360 and we're left with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

On to step 12:
When dividing 2550 by 621, we get 4 with a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 105237.8454
Subtract 2484 from 2550 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 13:
If we divide 660 by 621, we get 1 and a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 105237.84541
If we take 621 away from 660, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 14:
The number 621 fits into 390 0 times, leaving a remainder of 390.
The number 0 becomes the next digit in our result. 
Result so far: 105237.84541
The remainder is 390 after subtracting 0 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 15:
621 can be fit into 3900 6 times, resulting in a remainder of 174.
The number 6 becomes the next digit in our result. 
Result so far: 105237.8454106
If we take 3726 away from 3900, we end up with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Step 16:
When dividing 1740 by 621, we get 2 with a remainder of 498.
The next digit of our result is 2. 
Result so far: 105237.84541062
The remainder is 498 after subtracting 1242 from 1740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

The quotient of the division is 105237.84541062, and the remainder is 4.98e-07.
