70328471 ÷ 45 
The aim is to understand the frequency of 45 in 70328471.

Step 1:
If we divide 7 by 45, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 45

Step 2:
If we divide 70 by 45, we get 1 and a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 45 from 70, we get 25.
Bring next digit (3) of the dividend behind the 25 and repeat the process: 253 / 45

On to step 3:
The number 45 fits into 253 5 times, leaving a remainder of 28.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 225 from 253, we get 28.
Append the next digit (2) from the dividend to 28 and continue with: 282 / 45

Advancing to step 4:
When dividing 282 by 45, we get 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 156.0
If we take 270 away from 282, we end up with 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 45

Let's proceed to step 5:
45 goes into 128 2 times with a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 1562.0
Deduct 90 from 128 and we're left with 38.
Grab the next digit (4) from the dividend, add it to 38, then carry on: 384 / 45

Let's proceed to step 6:
If we divide 384 by 45, we get 8 and a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 15628.0
If we take 360 away from 384, we end up with 24.
Take the next digit (7) from the dividend and append it to 24, then repeat: 247 / 45

Let's proceed to step 7:
If we divide 247 by 45, we get 5 and a remainder of 22.
Use 5 as the next digit of our solution. 
Result so far: 156285.0
Subtract 225 from 247 to get 22.
Grab the next digit (1) from the dividend, add it to 22, then carry on: 221 / 45

On to step 8:
The number 45 fits into 221 4 times, leaving a remainder of 41.
The number 4 becomes the next digit in our result. 
Result so far: 1562854.0
If we subtract 180 from 221, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 9:
410 divided by 45 is 9 with a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 1562854.9
Subtracting 405 from 410 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 10:
50 divided by 45 is 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1562854.91
Subtracting 45 from 50 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 11:
45 goes into 50 1 times with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1562854.911
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 1562854.911, with a leftover of 0.0005.
