We're dividing 78051149 by 858 
The aim is to understand the frequency of 858 in 78051149.

Going ahead to step 1:
When dividing 7 by 858, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 858

Moving on to step 2:
858 goes into 78 0 times with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Bring next digit (0) of the dividend behind the 78 and repeat the process: 780 / 858

Advancing to step 3:
780 divided by 858 is 0 with a remainder of 780.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 780, we end up with 780.
Take the next digit (5) from the dividend and append it to 780, then repeat: 7805 / 858

On to step 4:
858 goes into 7805 9 times with a remainder of 83.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 7722 from 7805 to get 83.
Bring next digit (1) of the dividend behind the 83 and repeat the process: 831 / 858

Moving on to step 5:
858 can be fit into 831 0 times, resulting in a remainder of 831.
The next digit of our result is 0. 
Result so far: 90.0
If we subtract 0 from 831, we get 831.
Bring next digit (1) of the dividend behind the 831 and repeat the process: 8311 / 858

Going ahead to step 6:
If we divide 8311 by 858, we get 9 and a remainder of 589.
The number 9 becomes the next digit in our result. 
Result so far: 909.0
Subtracting 7722 from 8311 leaves us with 589.
Bring next digit (4) of the dividend behind the 589 and repeat the process: 5894 / 858

Let's proceed to step 7:
858 goes into 5894 6 times with a remainder of 746.
Put 6 as the next digit of the answer. 
Result so far: 9096.0
The remainder is 746 after subtracting 5148 from 5894.
Include the next digit (9) from the dividend after 746, then repeat: 7469 / 858

Moving on to step 8:
7469 divided by 858 is 8 with a remainder of 605.
Put 8 as the next digit of the answer. 
Result so far: 90968.0
The remainder is 605 after subtracting 6864 from 7469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

On to step 9:
The number 858 fits into 6050 7 times, leaving a remainder of 44.
Use 7 as the next digit of our solution. 
Result so far: 90968.7
If we subtract 6006 from 6050, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 10:
If we divide 440 by 858, we get 0 and a remainder of 440.
Write down 0 as next digit of the result. 
Result so far: 90968.7
Subtracting 0 from 440 leaves us with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 11:
The number 858 fits into 4400 5 times, leaving a remainder of 110.
Record the quotient 5 as the next digit in the result. 
Result so far: 90968.705
Subtracting 4290 from 4400 leaves us with 110.
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 12:
The number 858 fits into 1100 1 times, leaving a remainder of 242.
The next digit of our result is 1. 
Result so far: 90968.7051
The remainder is 242 after subtracting 858 from 1100.
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 13:
If we divide 2420 by 858, we get 2 and a remainder of 704.
The number 2 becomes the next digit in our result. 
Result so far: 90968.70512
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.

Advancing to step 14:
858 can be fit into 7040 8 times, resulting in a remainder of 176.
Write down 8 as next digit of the result. 
Result so far: 90968.705128
The remainder is 176 after subtracting 6864 from 7040.
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 15:
The number 858 fits into 1760 2 times, leaving a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 90968.7051282
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.

On to step 16:
440 divided by 858 is 0 with a remainder of 440.
Write down 0 as next digit of the result. 
Result so far: 90968.7051282
Deduct 0 from 440 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

The quotient of the division is 90968.7051282, and the remainder is 4.4e-07.
