We're dividing 61061058 by 621 
The aim is to understand the frequency of 621 in 61061058.

Moving on to step 1:
When dividing 6 by 621, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 621

Moving on to step 2:
The number 621 fits into 61 0 times, leaving a remainder of 61.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 61 and we're left with 61.
Take the next digit (0) from the dividend and append it to 61, then repeat: 610 / 621

Going ahead to step 3:
621 can be fit into 610 0 times, resulting in a remainder of 610.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 610 leaves us with 610.
Append the next digit (6) from the dividend to 610 and continue with: 6106 / 621

Going ahead to step 4:
If we divide 6106 by 621, we get 9 and a remainder of 517.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 517 after subtracting 5589 from 6106.
Grab the next digit (1) from the dividend, add it to 517, then carry on: 5171 / 621

On to step 5:
621 can be fit into 5171 8 times, resulting in a remainder of 203.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
If we take 4968 away from 5171, we end up with 203.
Bring next digit (0) of the dividend behind the 203 and repeat the process: 2030 / 621

Going ahead to step 6:
When dividing 2030 by 621, we get 3 with a remainder of 167.
Put 3 as the next digit of the answer. 
Result so far: 983.0
Subtracting 1863 from 2030 leaves us with 167.
Take the next digit (5) from the dividend and append it to 167, then repeat: 1675 / 621

On to step 7:
The number 621 fits into 1675 2 times, leaving a remainder of 433.
Use 2 as the next digit of our solution. 
Result so far: 9832.0
The remainder is 433 after subtracting 1242 from 1675.
Grab the next digit (8) from the dividend, add it to 433, then carry on: 4338 / 621

Step 8:
4338 divided by 621 is 6 with a remainder of 612.
The next digit of our result is 6. 
Result so far: 98326.0
If we subtract 3726 from 4338, we get 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Step 9:
621 goes into 6120 9 times with a remainder of 531.
Use 9 as the next digit of our solution. 
Result so far: 98326.9
Deduct 5589 from 6120 and we're left with 531.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

Let's proceed to step 10:
5310 divided by 621 is 8 with a remainder of 342.
Record the quotient 8 as the next digit in the result. 
Result so far: 98326.98
Deduct 4968 from 5310 and we're left with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

On to step 11:
The number 621 fits into 3420 5 times, leaving a remainder of 315.
The number 5 becomes the next digit in our result. 
Result so far: 98326.985
If we take 3105 away from 3420, we end up with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Moving on to step 12:
621 goes into 3150 5 times with a remainder of 45.
The next digit of our result is 5. 
Result so far: 98326.9855
If we subtract 3105 from 3150, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final result is 98326.9855 with a remainder of 0.00045.
