We divide 66343893 by 853
The aim is to understand the frequency of 853 in 66343893.

On to step 1:
853 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 853

On to step 2:
853 goes into 66 0 times with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Append the next digit (3) from the dividend to 66 and continue with: 663 / 853

Let's proceed to step 3:
If we divide 663 by 853, we get 0 and a remainder of 663.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 663 to get 663.
Bring next digit (4) of the dividend behind the 663 and repeat the process: 6634 / 853

Advancing to step 4:
853 goes into 6634 7 times with a remainder of 663.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 5971 from 6634 and we're left with 663.
Bring next digit (3) of the dividend behind the 663 and repeat the process: 6633 / 853

Moving on to step 5:
853 goes into 6633 7 times with a remainder of 662.
The next digit of our result is 7. 
Result so far: 77.0
If we subtract 5971 from 6633, we get 662.
Grab the next digit (8) from the dividend, add it to 662, then carry on: 6628 / 853

Step 6:
When dividing 6628 by 853, we get 7 with a remainder of 657.
The next digit of our result is 7. 
Result so far: 777.0
If we subtract 5971 from 6628, we get 657.
Take the next digit (9) from the dividend and append it to 657, then repeat: 6579 / 853

Let's proceed to step 7:
If we divide 6579 by 853, we get 7 and a remainder of 608.
Put 7 as the next digit of the answer. 
Result so far: 7777.0
If we subtract 5971 from 6579, we get 608.
Take the next digit (3) from the dividend and append it to 608, then repeat: 6083 / 853

Let's proceed to step 8:
When dividing 6083 by 853, we get 7 with a remainder of 112.
The number 7 becomes the next digit in our result. 
Result so far: 77777.0
Subtracting 5971 from 6083 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 9:
When dividing 1120 by 853, we get 1 with a remainder of 267.
Put 1 as the next digit of the answer. 
Result so far: 77777.1
Subtracting 853 from 1120 leaves us with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Moving on to step 10:
When dividing 2670 by 853, we get 3 with a remainder of 111.
Record the quotient 3 as the next digit in the result. 
Result so far: 77777.13
The remainder is 111 after subtracting 2559 from 2670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Advancing to step 11:
When dividing 1110 by 853, we get 1 with a remainder of 257.
The number 1 becomes the next digit in our result. 
Result so far: 77777.131
Subtracting 853 from 1110 leaves us with 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

On to step 12:
853 can be fit into 2570 3 times, resulting in a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 77777.1313
Subtracting 2559 from 2570 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 13:
853 goes into 110 0 times with a remainder of 110.
Write down 0 as next digit of the result. 
Result so far: 77777.1313
If we take 0 away from 110, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 14:
If we divide 1100 by 853, we get 1 and a remainder of 247.
Use 1 as the next digit of our solution. 
Result so far: 77777.131301
Subtracting 853 from 1100 leaves us with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Let's proceed to step 15:
853 can be fit into 2470 2 times, resulting in a remainder of 764.
Put 2 as the next digit of the answer. 
Result so far: 77777.1313012
The remainder is 764 after subtracting 1706 from 2470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7640, and continue the process.

Step 16:
The number 853 fits into 7640 8 times, leaving a remainder of 816.
The next digit of our result is 8. 
Result so far: 77777.13130128
If we subtract 6824 from 7640, we get 816.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8160, and continue the process.

In conclusion, the division gives 77777.13130128 with a balance of 8.16e-07.
