We look at the division of 35070463 by 858 
The aim is to understand the frequency of 858 in 35070463.

On to step 1:
When dividing 3 by 858, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 858

Advancing to step 2:
When dividing 35 by 858, we get 0 with a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Bring next digit (0) of the dividend behind the 35 and repeat the process: 350 / 858

On to step 3:
If we divide 350 by 858, we get 0 and a remainder of 350.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 350 leaves us with 350.
Take the next digit (7) from the dividend and append it to 350, then repeat: 3507 / 858

Let's proceed to step 4:
858 can be fit into 3507 4 times, resulting in a remainder of 75.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 3432 from 3507 to get 75.
Grab the next digit (0) from the dividend, add it to 75, then carry on: 750 / 858

On to step 5:
858 goes into 750 0 times with a remainder of 750.
The next digit of our result is 0. 
Result so far: 40.0
If we subtract 0 from 750, we get 750.
Bring next digit (4) of the dividend behind the 750 and repeat the process: 7504 / 858

Going ahead to step 6:
If we divide 7504 by 858, we get 8 and a remainder of 640.
The number 8 becomes the next digit in our result. 
Result so far: 408.0
If we take 6864 away from 7504, we end up with 640.
Bring next digit (6) of the dividend behind the 640 and repeat the process: 6406 / 858

On to step 7:
6406 divided by 858 is 7 with a remainder of 400.
Put 7 as the next digit of the answer. 
Result so far: 4087.0
Subtract 6006 from 6406 to get 400.
Grab the next digit (3) from the dividend, add it to 400, then carry on: 4003 / 858

Going ahead to step 8:
858 goes into 4003 4 times with a remainder of 571.
Record the quotient 4 as the next digit in the result. 
Result so far: 40874.0
Deduct 3432 from 4003 and we're left with 571.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5710, and continue the process.

Going ahead to step 9:
When dividing 5710 by 858, we get 6 with a remainder of 562.
Record the quotient 6 as the next digit in the result. 
Result so far: 40874.6
The remainder is 562 after subtracting 5148 from 5710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

On to step 10:
5620 divided by 858 is 6 with a remainder of 472.
Put 6 as the next digit of the answer. 
Result so far: 40874.66
The remainder is 472 after subtracting 5148 from 5620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Our division results in 40874.66 with a remaining 0.472.
