We look at the division of 70679309 by 457 
The aim is to understand the frequency of 457 in 70679309.

Going ahead to step 1:
If we divide 7 by 457, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 457

On to step 2:
457 goes into 70 0 times with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Include the next digit (6) from the dividend after 70, then repeat: 706 / 457

Step 3:
457 goes into 706 1 times with a remainder of 249.
The next digit of our result is 1. 
Result so far: 1.0
If we take 457 away from 706, we end up with 249.
Bring next digit (7) of the dividend behind the 249 and repeat the process: 2497 / 457

Advancing to step 4:
457 can be fit into 2497 5 times, resulting in a remainder of 212.
The next digit of our result is 5. 
Result so far: 15.0
Subtracting 2285 from 2497 leaves us with 212.
Take the next digit (9) from the dividend and append it to 212, then repeat: 2129 / 457

Step 5:
If we divide 2129 by 457, we get 4 and a remainder of 301.
Use 4 as the next digit of our solution. 
Result so far: 154.0
If we subtract 1828 from 2129, we get 301.
Fetch the next digit (3) from the dividend, attach it to 301 and continue: 3013 / 457

On to step 6:
457 can be fit into 3013 6 times, resulting in a remainder of 271.
Put 6 as the next digit of the answer. 
Result so far: 1546.0
If we subtract 2742 from 3013, we get 271.
Include the next digit (0) from the dividend after 271, then repeat: 2710 / 457

Step 7:
If we divide 2710 by 457, we get 5 and a remainder of 425.
Record the quotient 5 as the next digit in the result. 
Result so far: 15465.0
Subtract 2285 from 2710 to get 425.
Take the next digit (9) from the dividend and append it to 425, then repeat: 4259 / 457

Going ahead to step 8:
The number 457 fits into 4259 9 times, leaving a remainder of 146.
Record the quotient 9 as the next digit in the result. 
Result so far: 154659.0
Subtract 4113 from 4259 to get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Going ahead to step 9:
The number 457 fits into 1460 3 times, leaving a remainder of 89.
The number 3 becomes the next digit in our result. 
Result so far: 154659.3
If we subtract 1371 from 1460, we 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.

Going ahead to step 10:
When dividing 890 by 457, we get 1 with a remainder of 433.
Put 1 as the next digit of the answer. 
Result so far: 154659.31
Subtract 457 from 890 to get 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Step 11:
The number 457 fits into 4330 9 times, leaving a remainder of 217.
The next digit of our result is 9. 
Result so far: 154659.319
Deduct 4113 from 4330 and we're left with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

On to step 12:
457 goes into 2170 4 times with a remainder of 342.
The next digit of our result is 4. 
Result so far: 154659.3194
The remainder is 342 after subtracting 1828 from 2170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Step 13:
3420 divided by 457 is 7 with a remainder of 221.
Put 7 as the next digit of the answer. 
Result so far: 154659.31947
Deduct 3199 from 3420 and we're left with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Advancing to step 14:
If we divide 2210 by 457, we get 4 and a remainder of 382.
Put 4 as the next digit of the answer. 
Result so far: 154659.319474
If we take 1828 away from 2210, we end up with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

On to step 15:
3820 divided by 457 is 8 with a remainder of 164.
Record the quotient 8 as the next digit in the result. 
Result so far: 154659.3194748
The remainder is 164 after subtracting 3656 from 3820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Going ahead to step 16:
457 can be fit into 1640 3 times, resulting in a remainder of 269.
Use 3 as the next digit of our solution. 
Result so far: 154659.31947483
The remainder is 269 after subtracting 1371 from 1640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

In conclusion, the division gives 154659.31947483 with a balance of 2.69e-07.
