48219974 ÷ 858 
The aim is to understand the frequency of 858 in 48219974.

Let's proceed to step 1:
The number 858 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 858

Advancing to step 2:
858 can be fit into 48 0 times, resulting in a remainder of 48.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 48, we get 48.
Bring next digit (2) of the dividend behind the 48 and repeat the process: 482 / 858

Going ahead to step 3:
482 divided by 858 is 0 with a remainder of 482.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 482, we end up with 482.
Fetch the next digit (1) from the dividend, attach it to 482 and continue: 4821 / 858

Step 4:
If we divide 4821 by 858, we get 5 and a remainder of 531.
The next digit of our result is 5. 
Result so far: 5.0
If we take 4290 away from 4821, we end up with 531.
Bring next digit (9) of the dividend behind the 531 and repeat the process: 5319 / 858

On to step 5:
If we divide 5319 by 858, we get 6 and a remainder of 171.
The number 6 becomes the next digit in our result. 
Result so far: 56.0
If we take 5148 away from 5319, we end up with 171.
Grab the next digit (9) from the dividend, add it to 171, then carry on: 1719 / 858

On to step 6:
1719 divided by 858 is 2 with a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 562.0
Subtracting 1716 from 1719 leaves us with 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 858

Step 7:
858 can be fit into 37 0 times, resulting in a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 5620.0
If we take 0 away from 37, we end up with 37.
Fetch the next digit (4) from the dividend, attach it to 37 and continue: 374 / 858

Step 8:
If we divide 374 by 858, we get 0 and a remainder of 374.
Use 0 as the next digit of our solution. 
Result so far: 56200.0
If we take 0 away from 374, we end up with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Step 9:
When dividing 3740 by 858, we get 4 with a remainder of 308.
Use 4 as the next digit of our solution. 
Result so far: 56200.4
If we take 3432 away from 3740, we end up with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Let's proceed to step 10:
858 goes into 3080 3 times with a remainder of 506.
Write down 3 as next digit of the result. 
Result so far: 56200.43
If we subtract 2574 from 3080, we get 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Step 11:
5060 divided by 858 is 5 with a remainder of 770.
Record the quotient 5 as the next digit in the result. 
Result so far: 56200.435
Deduct 4290 from 5060 and we're left with 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Step 12:
If we divide 7700 by 858, we get 8 and a remainder of 836.
The number 8 becomes the next digit in our result. 
Result so far: 56200.4358
If we subtract 6864 from 7700, we get 836.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8360, and continue the process.

Moving on to step 13:
8360 divided by 858 is 9 with a remainder of 638.
The next digit of our result is 9. 
Result so far: 56200.43589
If we take 7722 away from 8360, we end up with 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

Advancing to step 14:
The number 858 fits into 6380 7 times, leaving a remainder of 374.
Put 7 as the next digit of the answer. 
Result so far: 56200.435897
If we subtract 6006 from 6380, we get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Step 15:
When dividing 3740 by 858, we get 4 with a remainder of 308.
Record the quotient 4 as the next digit in the result. 
Result so far: 56200.4358974
If we subtract 3432 from 3740, we get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Advancing to step 16:
858 goes into 3080 3 times with a remainder of 506.
Record the quotient 3 as the next digit in the result. 
Result so far: 56200.43589743
Subtract 2574 from 3080 to get 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

The final result is 56200.43589743 with a remainder of 5.06e-07.
