78041043 ÷ 857 
The aim is to understand the frequency of 857 in 78041043.

Advancing to step 1:
The number 857 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 857

Step 2:
857 can be fit into 78 0 times, resulting in a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Take the next digit (0) from the dividend and append it to 78, then repeat: 780 / 857

Going ahead to step 3:
The number 857 fits into 780 0 times, leaving a remainder of 780.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 780 and we're left with 780.
Include the next digit (4) from the dividend after 780, then repeat: 7804 / 857

Advancing to step 4:
857 can be fit into 7804 9 times, resulting in a remainder of 91.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 7713 from 7804 leaves us with 91.
Bring next digit (1) of the dividend behind the 91 and repeat the process: 911 / 857

Going ahead to step 5:
911 divided by 857 is 1 with a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 91.0
The remainder is 54 after subtracting 857 from 911.
Fetch the next digit (0) from the dividend, attach it to 54 and continue: 540 / 857

Moving on to step 6:
When dividing 540 by 857, we get 0 with a remainder of 540.
Use 0 as the next digit of our solution. 
Result so far: 910.0
If we take 0 away from 540, we end up with 540.
Take the next digit (4) from the dividend and append it to 540, then repeat: 5404 / 857

On to step 7:
5404 divided by 857 is 6 with a remainder of 262.
Write down 6 as next digit of the result. 
Result so far: 9106.0
If we take 5142 away from 5404, we end up with 262.
Append the next digit (3) from the dividend to 262 and continue with: 2623 / 857

Going ahead to step 8:
857 goes into 2623 3 times with a remainder of 52.
Write down 3 as next digit of the result. 
Result so far: 91063.0
If we subtract 2571 from 2623, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 9:
When dividing 520 by 857, we get 0 with a remainder of 520.
The number 0 becomes the next digit in our result. 
Result so far: 91063.0
If we take 0 away from 520, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Advancing to step 10:
When dividing 5200 by 857, we get 6 with a remainder of 58.
Use 6 as the next digit of our solution. 
Result so far: 91063.06
If we take 5142 away from 5200, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 11:
857 can be fit into 580 0 times, resulting in a remainder of 580.
Record the quotient 0 as the next digit in the result. 
Result so far: 91063.06
Subtracting 0 from 580 leaves us with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Step 12:
When dividing 5800 by 857, we get 6 with a remainder of 658.
Put 6 as the next digit of the answer. 
Result so far: 91063.0606
Deduct 5142 from 5800 and we're left with 658.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

Advancing to step 13:
When dividing 6580 by 857, we get 7 with a remainder of 581.
Put 7 as the next digit of the answer. 
Result so far: 91063.06067
Subtract 5999 from 6580 to get 581.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5810, and continue the process.

Advancing to step 14:
857 goes into 5810 6 times with a remainder of 668.
The number 6 becomes the next digit in our result. 
Result so far: 91063.060676
The remainder is 668 after subtracting 5142 from 5810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

Going ahead to step 15:
When dividing 6680 by 857, we get 7 with a remainder of 681.
Put 7 as the next digit of the answer. 
Result so far: 91063.0606767
If we subtract 5999 from 6680, we get 681.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6810, and continue the process.

Step 16:
6810 divided by 857 is 7 with a remainder of 811.
Write down 7 as next digit of the result. 
Result so far: 91063.06067677
Subtract 5999 from 6810 to get 811.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8110, and continue the process.

The final outcome is 91063.06067677, with a leftover of 8.11e-07.
