We're dividing 81956000 by 621 
The aim is to understand the frequency of 621 in 81956000.

Moving on to step 1:
8 divided by 621 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 621

Moving on to step 2:
81 divided by 621 is 0 with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Include the next digit (9) from the dividend after 81, then repeat: 819 / 621

Moving on to step 3:
621 goes into 819 1 times with a remainder of 198.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 621 from 819, we get 198.
Grab the next digit (5) from the dividend, add it to 198, then carry on: 1985 / 621

Step 4:
621 can be fit into 1985 3 times, resulting in a remainder of 122.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
The remainder is 122 after subtracting 1863 from 1985.
Fetch the next digit (6) from the dividend, attach it to 122 and continue: 1226 / 621

On to step 5:
If we divide 1226 by 621, we get 1 and a remainder of 605.
Write down 1 as next digit of the result. 
Result so far: 131.0
If we subtract 621 from 1226, we get 605.
Append the next digit (0) from the dividend to 605 and continue with: 6050 / 621

Let's proceed to step 6:
621 goes into 6050 9 times with a remainder of 461.
Record the quotient 9 as the next digit in the result. 
Result so far: 1319.0
If we take 5589 away from 6050, we end up with 461.
Take the next digit (0) from the dividend and append it to 461, then repeat: 4610 / 621

Going ahead to step 7:
621 can be fit into 4610 7 times, resulting in a remainder of 263.
Record the quotient 7 as the next digit in the result. 
Result so far: 13197.0
Subtracting 4347 from 4610 leaves us with 263.
Bring next digit (0) of the dividend behind the 263 and repeat the process: 2630 / 621

On to step 8:
621 can be fit into 2630 4 times, resulting in a remainder of 146.
Write down 4 as next digit of the result. 
Result so far: 131974.0
If we take 2484 away from 2630, we end up with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Moving on to step 9:
621 can be fit into 1460 2 times, resulting in a remainder of 218.
Use 2 as the next digit of our solution. 
Result so far: 131974.2
If we subtract 1242 from 1460, we get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Advancing to step 10:
2180 divided by 621 is 3 with a remainder of 317.
Use 3 as the next digit of our solution. 
Result so far: 131974.23
The remainder is 317 after subtracting 1863 from 2180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Moving on to step 11:
If we divide 3170 by 621, we get 5 and a remainder of 65.
The next digit of our result is 5. 
Result so far: 131974.235
Subtract 3105 from 3170 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 12:
If we divide 650 by 621, we get 1 and a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 131974.2351
Deduct 621 from 650 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 13:
290 divided by 621 is 0 with a remainder of 290.
Record the quotient 0 as the next digit in the result. 
Result so far: 131974.2351
The remainder is 290 after subtracting 0 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 14:
When dividing 2900 by 621, we get 4 with a remainder of 416.
Record the quotient 4 as the next digit in the result. 
Result so far: 131974.235104
The remainder is 416 after subtracting 2484 from 2900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Going ahead to step 15:
621 goes into 4160 6 times with a remainder of 434.
Write down 6 as next digit of the result. 
Result so far: 131974.2351046
Subtracting 3726 from 4160 leaves us with 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Step 16:
621 goes into 4340 6 times with a remainder of 614.
Record the quotient 6 as the next digit in the result. 
Result so far: 131974.23510466
Deduct 3726 from 4340 and we're left with 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

The quotient of the division is 131974.23510466, and the remainder is 6.14e-07.
