Let's divide 85032177 by 621
The aim is to understand the frequency of 621 in 85032177.

On to step 1:
621 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 621

Advancing to step 2:
621 can be fit into 85 0 times, resulting in a remainder of 85.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Append the next digit (0) from the dividend to 85 and continue with: 850 / 621

Let's proceed to step 3:
If we divide 850 by 621, we get 1 and a remainder of 229.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 621 from 850 to get 229.
Append the next digit (3) from the dividend to 229 and continue with: 2293 / 621

Step 4:
621 goes into 2293 3 times with a remainder of 430.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we take 1863 away from 2293, we end up with 430.
Fetch the next digit (2) from the dividend, attach it to 430 and continue: 4302 / 621

Going ahead to step 5:
The number 621 fits into 4302 6 times, leaving a remainder of 576.
Put 6 as the next digit of the answer. 
Result so far: 136.0
If we take 3726 away from 4302, we end up with 576.
Take the next digit (1) from the dividend and append it to 576, then repeat: 5761 / 621

On to step 6:
The number 621 fits into 5761 9 times, leaving a remainder of 172.
The next digit of our result is 9. 
Result so far: 1369.0
Subtract 5589 from 5761 to get 172.
Append the next digit (7) from the dividend to 172 and continue with: 1727 / 621

Going ahead to step 7:
When dividing 1727 by 621, we get 2 with a remainder of 485.
Write down 2 as next digit of the result. 
Result so far: 13692.0
The remainder is 485 after subtracting 1242 from 1727.
Bring next digit (7) of the dividend behind the 485 and repeat the process: 4857 / 621

On to step 8:
4857 divided by 621 is 7 with a remainder of 510.
Use 7 as the next digit of our solution. 
Result so far: 136927.0
The remainder is 510 after subtracting 4347 from 4857.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Moving on to step 9:
The number 621 fits into 5100 8 times, leaving a remainder of 132.
Use 8 as the next digit of our solution. 
Result so far: 136927.8
If we take 4968 away from 5100, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Let's proceed to step 10:
The number 621 fits into 1320 2 times, leaving a remainder of 78.
The next digit of our result is 2. 
Result so far: 136927.82
Subtracting 1242 from 1320 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 11:
780 divided by 621 is 1 with a remainder of 159.
Put 1 as the next digit of the answer. 
Result so far: 136927.821
Subtracting 621 from 780 leaves us with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Going ahead to step 12:
If we divide 1590 by 621, we get 2 and a remainder of 348.
Record the quotient 2 as the next digit in the result. 
Result so far: 136927.8212
The remainder is 348 after subtracting 1242 from 1590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Advancing to step 13:
3480 divided by 621 is 5 with a remainder of 375.
The number 5 becomes the next digit in our result. 
Result so far: 136927.82125
The remainder is 375 after subtracting 3105 from 3480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

On to step 14:
3750 divided by 621 is 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 136927.821256
Subtracting 3726 from 3750 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 15:
The number 621 fits into 240 0 times, leaving a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 136927.821256
Subtract 0 from 240 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 16:
2400 divided by 621 is 3 with a remainder of 537.
Write down 3 as next digit of the result. 
Result so far: 136927.82125603
Deduct 1863 from 2400 and we're left with 537.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5370, and continue the process.

The final result is 136927.82125603 with a remainder of 5.37e-07.
