84321195 ÷ 857 
The aim is to understand the frequency of 857 in 84321195.

Going ahead to step 1:
When dividing 8 by 857, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 857

Step 2:
When dividing 84 by 857, we get 0 with a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 84 to get 84.
Fetch the next digit (3) from the dividend, attach it to 84 and continue: 843 / 857

On to step 3:
843 divided by 857 is 0 with a remainder of 843.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 843 and we're left with 843.
Bring next digit (2) of the dividend behind the 843 and repeat the process: 8432 / 857

Moving on to step 4:
857 can be fit into 8432 9 times, resulting in a remainder of 719.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 7713 from 8432, we get 719.
Fetch the next digit (1) from the dividend, attach it to 719 and continue: 7191 / 857

On to step 5:
7191 divided by 857 is 8 with a remainder of 335.
The number 8 becomes the next digit in our result. 
Result so far: 98.0
Deduct 6856 from 7191 and we're left with 335.
Grab the next digit (1) from the dividend, add it to 335, then carry on: 3351 / 857

Step 6:
When dividing 3351 by 857, we get 3 with a remainder of 780.
Write down 3 as next digit of the result. 
Result so far: 983.0
Subtracting 2571 from 3351 leaves us with 780.
Grab the next digit (9) from the dividend, add it to 780, then carry on: 7809 / 857

Step 7:
When dividing 7809 by 857, we get 9 with a remainder of 96.
The next digit of our result is 9. 
Result so far: 9839.0
If we take 7713 away from 7809, we end up with 96.
Take the next digit (5) from the dividend and append it to 96, then repeat: 965 / 857

Advancing to step 8:
If we divide 965 by 857, we get 1 and a remainder of 108.
Use 1 as the next digit of our solution. 
Result so far: 98391.0
Subtracting 857 from 965 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 9:
If we divide 1080 by 857, we get 1 and a remainder of 223.
Write down 1 as next digit of the result. 
Result so far: 98391.1
Subtract 857 from 1080 to get 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Step 10:
The number 857 fits into 2230 2 times, leaving a remainder of 516.
The next digit of our result is 2. 
Result so far: 98391.12
The remainder is 516 after subtracting 1714 from 2230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Step 11:
857 goes into 5160 6 times with a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 98391.126
The remainder is 18 after subtracting 5142 from 5160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 12:
180 divided by 857 is 0 with a remainder of 180.
Put 0 as the next digit of the answer. 
Result so far: 98391.126
Subtract 0 from 180 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 13:
If we divide 1800 by 857, we get 2 and a remainder of 86.
Record the quotient 2 as the next digit in the result. 
Result so far: 98391.12602
Deduct 1714 from 1800 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 14:
857 can be fit into 860 1 times, resulting in a remainder of 3.
The next digit of our result is 1. 
Result so far: 98391.126021
Deduct 857 from 860 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 15:
The number 857 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 98391.126021
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 16:
If we divide 300 by 857, we get 0 and a remainder of 300.
Put 0 as the next digit of the answer. 
Result so far: 98391.126021
Deduct 0 from 300 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final outcome is 98391.126021, with a leftover of 3e-07.
