Let's divide 71993174 by 858
The aim is to understand the frequency of 858 in 71993174.

Let's proceed to step 1:
If we divide 7 by 858, 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.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 858

Moving on to step 2:
The number 858 fits into 71 0 times, leaving a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 71, we get 71.
Append the next digit (9) from the dividend to 71 and continue with: 719 / 858

Going ahead to step 3:
719 divided by 858 is 0 with a remainder of 719.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 719 leaves us with 719.
Include the next digit (9) from the dividend after 719, then repeat: 7199 / 858

Going ahead to step 4:
858 goes into 7199 8 times with a remainder of 335.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 6864 away from 7199, we end up with 335.
Bring next digit (3) of the dividend behind the 335 and repeat the process: 3353 / 858

Moving on to step 5:
The number 858 fits into 3353 3 times, leaving a remainder of 779.
The next digit of our result is 3. 
Result so far: 83.0
If we subtract 2574 from 3353, we get 779.
Include the next digit (1) from the dividend after 779, then repeat: 7791 / 858

Moving on to step 6:
When dividing 7791 by 858, we get 9 with a remainder of 69.
The number 9 becomes the next digit in our result. 
Result so far: 839.0
The remainder is 69 after subtracting 7722 from 7791.
Take the next digit (7) from the dividend and append it to 69, then repeat: 697 / 858

On to step 7:
697 divided by 858 is 0 with a remainder of 697.
The number 0 becomes the next digit in our result. 
Result so far: 8390.0
The remainder is 697 after subtracting 0 from 697.
Take the next digit (4) from the dividend and append it to 697, then repeat: 6974 / 858

Let's proceed to step 8:
6974 divided by 858 is 8 with a remainder of 110.
Put 8 as the next digit of the answer. 
Result so far: 83908.0
Subtract 6864 from 6974 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 9:
The number 858 fits into 1100 1 times, leaving a remainder of 242.
Write down 1 as next digit of the result. 
Result so far: 83908.1
If we subtract 858 from 1100, we get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Let's proceed to step 10:
2420 divided by 858 is 2 with a remainder of 704.
The next digit of our result is 2. 
Result so far: 83908.12
Subtracting 1716 from 2420 leaves us with 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

On to step 11:
When dividing 7040 by 858, we get 8 with a remainder of 176.
Record the quotient 8 as the next digit in the result. 
Result so far: 83908.128
Subtract 6864 from 7040 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 12:
858 can be fit into 1760 2 times, resulting in a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 83908.1282
The remainder is 44 after subtracting 1716 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 13:
When dividing 440 by 858, we get 0 with a remainder of 440.
The next digit of our result is 0. 
Result so far: 83908.1282
The remainder is 440 after subtracting 0 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 14:
When dividing 4400 by 858, we get 5 with a remainder of 110.
The next digit of our result is 5. 
Result so far: 83908.128205
The remainder is 110 after subtracting 4290 from 4400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 15:
If we divide 1100 by 858, we get 1 and a remainder of 242.
Record the quotient 1 as the next digit in the result. 
Result so far: 83908.1282051
If we subtract 858 from 1100, we get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Going ahead to step 16:
858 can be fit into 2420 2 times, resulting in a remainder of 704.
Write down 2 as next digit of the result. 
Result so far: 83908.12820512
The remainder is 704 after subtracting 1716 from 2420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

After the division, we end up with 83908.12820512 and a remainder of 7.04e-07.
