We look at the division of 61680105 by 745 
The aim is to understand the frequency of 745 in 61680105.

Let's proceed to step 1:
The number 745 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 745

Going ahead to step 2:
The number 745 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.
Append the next digit (6) from the dividend to 61 and continue with: 616 / 745

Step 3:
If we divide 616 by 745, we get 0 and a remainder of 616.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 616, we end up with 616.
Grab the next digit (8) from the dividend, add it to 616, then carry on: 6168 / 745

On to step 4:
745 goes into 6168 8 times with a remainder of 208.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 5960 from 6168, we get 208.
Bring next digit (0) of the dividend behind the 208 and repeat the process: 2080 / 745

Going ahead to step 5:
When dividing 2080 by 745, we get 2 with a remainder of 590.
Put 2 as the next digit of the answer. 
Result so far: 82.0
Subtract 1490 from 2080 to get 590.
Bring next digit (1) of the dividend behind the 590 and repeat the process: 5901 / 745

Going ahead to step 6:
The number 745 fits into 5901 7 times, leaving a remainder of 686.
Put 7 as the next digit of the answer. 
Result so far: 827.0
If we subtract 5215 from 5901, we get 686.
Include the next digit (0) from the dividend after 686, then repeat: 6860 / 745

Advancing to step 7:
The number 745 fits into 6860 9 times, leaving a remainder of 155.
Write down 9 as next digit of the result. 
Result so far: 8279.0
Subtract 6705 from 6860 to get 155.
Fetch the next digit (5) from the dividend, attach it to 155 and continue: 1555 / 745

Let's proceed to step 8:
1555 divided by 745 is 2 with a remainder of 65.
Record the quotient 2 as the next digit in the result. 
Result so far: 82792.0
If we subtract 1490 from 1555, we 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.

Let's proceed to step 9:
650 divided by 745 is 0 with a remainder of 650.
The number 0 becomes the next digit in our result. 
Result so far: 82792.0
If we take 0 away from 650, we end up with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Going ahead to step 10:
The number 745 fits into 6500 8 times, leaving a remainder of 540.
Put 8 as the next digit of the answer. 
Result so far: 82792.08
The remainder is 540 after subtracting 5960 from 6500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Step 11:
745 can be fit into 5400 7 times, resulting in a remainder of 185.
Put 7 as the next digit of the answer. 
Result so far: 82792.087
Subtract 5215 from 5400 to get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Going ahead to step 12:
The number 745 fits into 1850 2 times, leaving a remainder of 360.
Put 2 as the next digit of the answer. 
Result so far: 82792.0872
Subtract 1490 from 1850 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 13:
When dividing 3600 by 745, we get 4 with a remainder of 620.
The next digit of our result is 4. 
Result so far: 82792.08724
Subtracting 2980 from 3600 leaves us with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Step 14:
6200 divided by 745 is 8 with a remainder of 240.
The next digit of our result is 8. 
Result so far: 82792.087248
Subtract 5960 from 6200 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 15:
If we divide 2400 by 745, we get 3 and a remainder of 165.
Put 3 as the next digit of the answer. 
Result so far: 82792.0872483
Subtracting 2235 from 2400 leaves us with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Advancing to step 16:
When dividing 1650 by 745, we get 2 with a remainder of 160.
The next digit of our result is 2. 
Result so far: 82792.08724832
Subtract 1490 from 1650 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final outcome is 82792.08724832, with a leftover of 1.6e-07.
