70011721 ÷ 579 
The aim is to understand the frequency of 579 in 70011721.

Moving on to step 1:
579 goes into 7 0 times with 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.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 579

Advancing to step 2:
If we divide 70 by 579, we get 0 and a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 70, we get 70.
Take the next digit (0) from the dividend and append it to 70, then repeat: 700 / 579

Let's proceed to step 3:
If we divide 700 by 579, we get 1 and a remainder of 121.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 579 from 700 and we're left with 121.
Grab the next digit (1) from the dividend, add it to 121, then carry on: 1211 / 579

Step 4:
The number 579 fits into 1211 2 times, leaving a remainder of 53.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 1158 from 1211 and we're left with 53.
Grab the next digit (1) from the dividend, add it to 53, then carry on: 531 / 579

Step 5:
579 can be fit into 531 0 times, resulting in a remainder of 531.
Put 0 as the next digit of the answer. 
Result so far: 120.0
Subtract 0 from 531 to get 531.
Take the next digit (7) from the dividend and append it to 531, then repeat: 5317 / 579

Going ahead to step 6:
579 can be fit into 5317 9 times, resulting in a remainder of 106.
Put 9 as the next digit of the answer. 
Result so far: 1209.0
Subtracting 5211 from 5317 leaves us with 106.
Fetch the next digit (2) from the dividend, attach it to 106 and continue: 1062 / 579

On to step 7:
1062 divided by 579 is 1 with a remainder of 483.
The next digit of our result is 1. 
Result so far: 12091.0
Subtracting 579 from 1062 leaves us with 483.
Bring next digit (1) of the dividend behind the 483 and repeat the process: 4831 / 579

Step 8:
If we divide 4831 by 579, we get 8 and a remainder of 199.
Put 8 as the next digit of the answer. 
Result so far: 120918.0
The remainder is 199 after subtracting 4632 from 4831.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Advancing to step 9:
579 goes into 1990 3 times with a remainder of 253.
The next digit of our result is 3. 
Result so far: 120918.3
Subtract 1737 from 1990 to get 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Going ahead to step 10:
The number 579 fits into 2530 4 times, leaving a remainder of 214.
The next digit of our result is 4. 
Result so far: 120918.34
Subtract 2316 from 2530 to get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Let's proceed to step 11:
579 can be fit into 2140 3 times, resulting in a remainder of 403.
The next digit of our result is 3. 
Result so far: 120918.343
The remainder is 403 after subtracting 1737 from 2140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

On to step 12:
The number 579 fits into 4030 6 times, leaving a remainder of 556.
The number 6 becomes the next digit in our result. 
Result so far: 120918.3436
Deduct 3474 from 4030 and we're left with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Advancing to step 13:
When dividing 5560 by 579, we get 9 with a remainder of 349.
Record the quotient 9 as the next digit in the result. 
Result so far: 120918.34369
If we subtract 5211 from 5560, we get 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Step 14:
If we divide 3490 by 579, we get 6 and a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 120918.343696
If we take 3474 away from 3490, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 15:
The number 579 fits into 160 0 times, leaving a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 120918.343696
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 16:
When dividing 1600 by 579, we get 2 with a remainder of 442.
Put 2 as the next digit of the answer. 
Result so far: 120918.34369602
If we take 1158 away from 1600, we end up with 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

In conclusion, the division gives 120918.34369602 with a balance of 4.42e-07.
