Let's divide 61646291 by 857
The aim is to understand the frequency of 857 in 61646291.

Let's proceed to step 1:
When dividing 6 by 857, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 857

Step 2:
The number 857 fits into 61 0 times, leaving a remainder of 61.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 61, we get 61.
Append the next digit (6) from the dividend to 61 and continue with: 616 / 857

Moving on to step 3:
The number 857 fits into 616 0 times, leaving a remainder of 616.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 616, we end up with 616.
Grab the next digit (4) from the dividend, add it to 616, then carry on: 6164 / 857

Going ahead to step 4:
857 can be fit into 6164 7 times, resulting in a remainder of 165.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 165 after subtracting 5999 from 6164.
Grab the next digit (6) from the dividend, add it to 165, then carry on: 1656 / 857

On to step 5:
When dividing 1656 by 857, we get 1 with a remainder of 799.
Put 1 as the next digit of the answer. 
Result so far: 71.0
The remainder is 799 after subtracting 857 from 1656.
Bring next digit (2) of the dividend behind the 799 and repeat the process: 7992 / 857

Let's proceed to step 6:
If we divide 7992 by 857, we get 9 and a remainder of 279.
Record the quotient 9 as the next digit in the result. 
Result so far: 719.0
Subtract 7713 from 7992 to get 279.
Take the next digit (9) from the dividend and append it to 279, then repeat: 2799 / 857

Going ahead to step 7:
2799 divided by 857 is 3 with a remainder of 228.
Use 3 as the next digit of our solution. 
Result so far: 7193.0
If we subtract 2571 from 2799, we get 228.
Bring next digit (1) of the dividend behind the 228 and repeat the process: 2281 / 857

On to step 8:
When dividing 2281 by 857, we get 2 with a remainder of 567.
Record the quotient 2 as the next digit in the result. 
Result so far: 71932.0
If we subtract 1714 from 2281, we get 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

Going ahead to step 9:
If we divide 5670 by 857, we get 6 and a remainder of 528.
Put 6 as the next digit of the answer. 
Result so far: 71932.6
Subtract 5142 from 5670 to get 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Moving on to step 10:
When dividing 5280 by 857, we get 6 with a remainder of 138.
Put 6 as the next digit of the answer. 
Result so far: 71932.66
If we subtract 5142 from 5280, we get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

In conclusion, the division gives 71932.66 with a balance of 0.138.
