Let's divide 93251946 by 621
The aim is to understand the frequency of 621 in 93251946.

Advancing to step 1:
If we divide 9 by 621, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 621

Let's proceed to step 2:
621 can be fit into 93 0 times, resulting in a remainder of 93.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 93 after subtracting 0 from 93.
Append the next digit (2) from the dividend to 93 and continue with: 932 / 621

Step 3:
621 goes into 932 1 times with a remainder of 311.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 621 away from 932, we end up with 311.
Append the next digit (5) from the dividend to 311 and continue with: 3115 / 621

Advancing to step 4:
3115 divided by 621 is 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtracting 3105 from 3115 leaves us with 10.
Fetch the next digit (1) from the dividend, attach it to 10 and continue: 101 / 621

On to step 5:
If we divide 101 by 621, we get 0 and a remainder of 101.
Use 0 as the next digit of our solution. 
Result so far: 150.0
Subtract 0 from 101 to get 101.
Include the next digit (9) from the dividend after 101, then repeat: 1019 / 621

On to step 6:
621 can be fit into 1019 1 times, resulting in a remainder of 398.
The number 1 becomes the next digit in our result. 
Result so far: 1501.0
Deduct 621 from 1019 and we're left with 398.
Grab the next digit (4) from the dividend, add it to 398, then carry on: 3984 / 621

On to step 7:
When dividing 3984 by 621, we get 6 with a remainder of 258.
Write down 6 as next digit of the result. 
Result so far: 15016.0
Subtracting 3726 from 3984 leaves us with 258.
Append the next digit (6) from the dividend to 258 and continue with: 2586 / 621

Advancing to step 8:
621 can be fit into 2586 4 times, resulting in a remainder of 102.
Put 4 as the next digit of the answer. 
Result so far: 150164.0
Subtracting 2484 from 2586 leaves us with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Step 9:
621 goes into 1020 1 times with a remainder of 399.
Write down 1 as next digit of the result. 
Result so far: 150164.1
Subtracting 621 from 1020 leaves us with 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

Step 10:
3990 divided by 621 is 6 with a remainder of 264.
The next digit of our result is 6. 
Result so far: 150164.16
If we subtract 3726 from 3990, we get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Moving on to step 11:
621 goes into 2640 4 times with a remainder of 156.
The number 4 becomes the next digit in our result. 
Result so far: 150164.164
If we take 2484 away from 2640, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Advancing to step 12:
The number 621 fits into 1560 2 times, leaving a remainder of 318.
Record the quotient 2 as the next digit in the result. 
Result so far: 150164.1642
If we subtract 1242 from 1560, we get 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Moving on to step 13:
621 can be fit into 3180 5 times, resulting in a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 150164.16425
The remainder is 75 after subtracting 3105 from 3180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 14:
621 can be fit into 750 1 times, resulting in a remainder of 129.
Use 1 as the next digit of our solution. 
Result so far: 150164.164251
If we take 621 away from 750, we end up with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Advancing to step 15:
The number 621 fits into 1290 2 times, leaving a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 150164.1642512
If we take 1242 away from 1290, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 16:
If we divide 480 by 621, we get 0 and a remainder of 480.
Use 0 as the next digit of our solution. 
Result so far: 150164.1642512
The remainder is 480 after subtracting 0 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

The final result is 150164.1642512 with a remainder of 4.8e-07.
