We look at the division of 61783558 by 105 
The aim is to understand the frequency of 105 in 61783558.

Step 1:
105 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 105

Step 2:
105 goes into 61 0 times with a remainder of 61.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 61 after subtracting 0 from 61.
Bring next digit (7) of the dividend behind the 61 and repeat the process: 617 / 105

On to step 3:
If we divide 617 by 105, we get 5 and a remainder of 92.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 525 from 617 and we're left with 92.
Take the next digit (8) from the dividend and append it to 92, then repeat: 928 / 105

Let's proceed to step 4:
928 divided by 105 is 8 with a remainder of 88.
The next digit of our result is 8. 
Result so far: 58.0
Subtract 840 from 928 to get 88.
Bring next digit (3) of the dividend behind the 88 and repeat the process: 883 / 105

Going ahead to step 5:
The number 105 fits into 883 8 times, leaving a remainder of 43.
The next digit of our result is 8. 
Result so far: 588.0
If we take 840 away from 883, we end up with 43.
Take the next digit (5) from the dividend and append it to 43, then repeat: 435 / 105

Going ahead to step 6:
When dividing 435 by 105, we get 4 with a remainder of 15.
The number 4 becomes the next digit in our result. 
Result so far: 5884.0
Deduct 420 from 435 and we're left with 15.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 105

Moving on to step 7:
The number 105 fits into 155 1 times, leaving a remainder of 50.
Use 1 as the next digit of our solution. 
Result so far: 58841.0
The remainder is 50 after subtracting 105 from 155.
Include the next digit (8) from the dividend after 50, then repeat: 508 / 105

On to step 8:
105 goes into 508 4 times with a remainder of 88.
Write down 4 as next digit of the result. 
Result so far: 588414.0
Subtracting 420 from 508 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 9:
When dividing 880 by 105, we get 8 with a remainder of 40.
The next digit of our result is 8. 
Result so far: 588414.8
If we take 840 away from 880, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
105 can be fit into 400 3 times, resulting in a remainder of 85.
Use 3 as the next digit of our solution. 
Result so far: 588414.83
If we subtract 315 from 400, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 11:
The number 105 fits into 850 8 times, leaving a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 588414.838
Subtract 840 from 850 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 12:
The number 105 fits into 100 0 times, leaving a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 588414.838
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 13:
If we divide 1000 by 105, we get 9 and a remainder of 55.
The number 9 becomes the next digit in our result. 
Result so far: 588414.83809
Deduct 945 from 1000 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 14:
The number 105 fits into 550 5 times, leaving a remainder of 25.
The next digit of our result is 5. 
Result so far: 588414.838095
Subtract 525 from 550 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 15:
105 goes into 250 2 times with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 588414.8380952
If we subtract 210 from 250, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 16:
If we divide 400 by 105, we get 3 and a remainder of 85.
The number 3 becomes the next digit in our result. 
Result so far: 588414.83809523
The remainder is 85 after subtracting 315 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

The final outcome is 588414.83809523, with a leftover of 8.5e-08.
