Let's divide 72085821 by 157
The aim is to understand the frequency of 157 in 72085821.

Let's proceed to step 1:
When dividing 7 by 157, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 157

Advancing to step 2:
157 goes into 72 0 times with a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Bring next digit (0) of the dividend behind the 72 and repeat the process: 720 / 157

Advancing to step 3:
157 can be fit into 720 4 times, resulting in a remainder of 92.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 628 from 720 to get 92.
Append the next digit (8) from the dividend to 92 and continue with: 928 / 157

Moving on to step 4:
928 divided by 157 is 5 with a remainder of 143.
Write down 5 as next digit of the result. 
Result so far: 45.0
If we subtract 785 from 928, we get 143.
Fetch the next digit (5) from the dividend, attach it to 143 and continue: 1435 / 157

Moving on to step 5:
1435 divided by 157 is 9 with a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 459.0
Subtract 1413 from 1435 to get 22.
Append the next digit (8) from the dividend to 22 and continue with: 228 / 157

Step 6:
157 goes into 228 1 times with a remainder of 71.
Use 1 as the next digit of our solution. 
Result so far: 4591.0
Subtracting 157 from 228 leaves us with 71.
Take the next digit (2) from the dividend and append it to 71, then repeat: 712 / 157

Step 7:
157 can be fit into 712 4 times, resulting in a remainder of 84.
Put 4 as the next digit of the answer. 
Result so far: 45914.0
Subtract 628 from 712 to get 84.
Bring next digit (1) of the dividend behind the 84 and repeat the process: 841 / 157

Let's proceed to step 8:
157 goes into 841 5 times with a remainder of 56.
The next digit of our result is 5. 
Result so far: 459145.0
If we subtract 785 from 841, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 9:
If we divide 560 by 157, we get 3 and a remainder of 89.
Record the quotient 3 as the next digit in the result. 
Result so far: 459145.3
Subtract 471 from 560 to get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Step 10:
157 goes into 890 5 times with a remainder of 105.
Write down 5 as next digit of the result. 
Result so far: 459145.35
Subtract 785 from 890 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

On to step 11:
157 goes into 1050 6 times with a remainder of 108.
Record the quotient 6 as the next digit in the result. 
Result so far: 459145.356
If we subtract 942 from 1050, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 12:
1080 divided by 157 is 6 with a remainder of 138.
Use 6 as the next digit of our solution. 
Result so far: 459145.3566
Subtracting 942 from 1080 leaves us with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

The final outcome is 459145.3566, with a leftover of 0.00138.
