80157030 ÷ 925 
The aim is to understand the frequency of 925 in 80157030.

Step 1:
If we divide 8 by 925, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 925

Moving on to step 2:
If we divide 80 by 925, we get 0 and a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Grab the next digit (1) from the dividend, add it to 80, then carry on: 801 / 925

Moving on to step 3:
925 goes into 801 0 times with a remainder of 801.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 801, we end up with 801.
Grab the next digit (5) from the dividend, add it to 801, then carry on: 8015 / 925

Advancing to step 4:
925 can be fit into 8015 8 times, resulting in a remainder of 615.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 615 after subtracting 7400 from 8015.
Fetch the next digit (7) from the dividend, attach it to 615 and continue: 6157 / 925

Advancing to step 5:
925 can be fit into 6157 6 times, resulting in a remainder of 607.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
If we subtract 5550 from 6157, we get 607.
Append the next digit (0) from the dividend to 607 and continue with: 6070 / 925

Advancing to step 6:
925 goes into 6070 6 times with a remainder of 520.
Put 6 as the next digit of the answer. 
Result so far: 866.0
Subtract 5550 from 6070 to get 520.
Bring next digit (3) of the dividend behind the 520 and repeat the process: 5203 / 925

Advancing to step 7:
The number 925 fits into 5203 5 times, leaving a remainder of 578.
Write down 5 as next digit of the result. 
Result so far: 8665.0
Deduct 4625 from 5203 and we're left with 578.
Fetch the next digit (0) from the dividend, attach it to 578 and continue: 5780 / 925

On to step 8:
925 goes into 5780 6 times with a remainder of 230.
Record the quotient 6 as the next digit in the result. 
Result so far: 86656.0
If we take 5550 away from 5780, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 9:
2300 divided by 925 is 2 with a remainder of 450.
Put 2 as the next digit of the answer. 
Result so far: 86656.2
Subtract 1850 from 2300 to get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Step 10:
925 goes into 4500 4 times with a remainder of 800.
Write down 4 as next digit of the result. 
Result so far: 86656.24
The remainder is 800 after subtracting 3700 from 4500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Step 11:
If we divide 8000 by 925, we get 8 and a remainder of 600.
Put 8 as the next digit of the answer. 
Result so far: 86656.248
If we subtract 7400 from 8000, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Step 12:
When dividing 6000 by 925, we get 6 with a remainder of 450.
Write down 6 as next digit of the result. 
Result so far: 86656.2486
If we subtract 5550 from 6000, we get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 13:
If we divide 4500 by 925, we get 4 and a remainder of 800.
Put 4 as the next digit of the answer. 
Result so far: 86656.24864
If we take 3700 away from 4500, we end up with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Step 14:
If we divide 8000 by 925, we get 8 and a remainder of 600.
Record the quotient 8 as the next digit in the result. 
Result so far: 86656.248648
If we take 7400 away from 8000, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Advancing to step 15:
925 can be fit into 6000 6 times, resulting in a remainder of 450.
Use 6 as the next digit of our solution. 
Result so far: 86656.2486486
Deduct 5550 from 6000 and we're left with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Advancing to step 16:
The number 925 fits into 4500 4 times, leaving a remainder of 800.
Write down 4 as next digit of the result. 
Result so far: 86656.24864864
If we take 3700 away from 4500, we end up with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Our division results in 86656.24864864 with a remaining 8e-07.
