54040861 divided by 745 
The aim is to understand the frequency of 745 in 54040861.

Going ahead to step 1:
745 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 745

On to step 2:
The number 745 fits into 54 0 times, leaving a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Include the next digit (0) from the dividend after 54, then repeat: 540 / 745

On to step 3:
If we divide 540 by 745, we get 0 and a remainder of 540.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 540, we get 540.
Grab the next digit (4) from the dividend, add it to 540, then carry on: 5404 / 745

Let's proceed to step 4:
The number 745 fits into 5404 7 times, leaving a remainder of 189.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 5215 away from 5404, we end up with 189.
Bring next digit (0) of the dividend behind the 189 and repeat the process: 1890 / 745

On to step 5:
745 goes into 1890 2 times with a remainder of 400.
The next digit of our result is 2. 
Result so far: 72.0
Deduct 1490 from 1890 and we're left with 400.
Take the next digit (8) from the dividend and append it to 400, then repeat: 4008 / 745

Step 6:
745 goes into 4008 5 times with a remainder of 283.
Put 5 as the next digit of the answer. 
Result so far: 725.0
Subtract 3725 from 4008 to get 283.
Grab the next digit (6) from the dividend, add it to 283, then carry on: 2836 / 745

Step 7:
The number 745 fits into 2836 3 times, leaving a remainder of 601.
The number 3 becomes the next digit in our result. 
Result so far: 7253.0
Deduct 2235 from 2836 and we're left with 601.
Bring next digit (1) of the dividend behind the 601 and repeat the process: 6011 / 745

Moving on to step 8:
745 can be fit into 6011 8 times, resulting in a remainder of 51.
The number 8 becomes the next digit in our result. 
Result so far: 72538.0
Subtracting 5960 from 6011 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 9:
745 can be fit into 510 0 times, resulting in a remainder of 510.
Put 0 as the next digit of the answer. 
Result so far: 72538.0
Subtracting 0 from 510 leaves us with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Advancing to step 10:
745 goes into 5100 6 times with a remainder of 630.
The number 6 becomes the next digit in our result. 
Result so far: 72538.06
If we subtract 4470 from 5100, we get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Advancing to step 11:
6300 divided by 745 is 8 with a remainder of 340.
Use 8 as the next digit of our solution. 
Result so far: 72538.068
Subtracting 5960 from 6300 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 12:
When dividing 3400 by 745, we get 4 with a remainder of 420.
The next digit of our result is 4. 
Result so far: 72538.0684
Deduct 2980 from 3400 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Going ahead to step 13:
The number 745 fits into 4200 5 times, leaving a remainder of 475.
Put 5 as the next digit of the answer. 
Result so far: 72538.06845
Subtracting 3725 from 4200 leaves us with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

On to step 14:
4750 divided by 745 is 6 with a remainder of 280.
Record the quotient 6 as the next digit in the result. 
Result so far: 72538.068456
Subtract 4470 from 4750 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 15:
745 goes into 2800 3 times with a remainder of 565.
Use 3 as the next digit of our solution. 
Result so far: 72538.0684563
Subtract 2235 from 2800 to get 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

Going ahead to step 16:
The number 745 fits into 5650 7 times, leaving a remainder of 435.
Use 7 as the next digit of our solution. 
Result so far: 72538.06845637
If we take 5215 away from 5650, we end up with 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

The final outcome is 72538.06845637, with a leftover of 4.35e-07.
