53096692 divided by 646 
The aim is to understand the frequency of 646 in 53096692.

Going ahead to step 1:
646 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 646

On to step 2:
53 divided by 646 is 0 with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Bring next digit (0) of the dividend behind the 53 and repeat the process: 530 / 646

Step 3:
If we divide 530 by 646, we get 0 and a remainder of 530.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 530 leaves us with 530.
Fetch the next digit (9) from the dividend, attach it to 530 and continue: 5309 / 646

Step 4:
646 can be fit into 5309 8 times, resulting in a remainder of 141.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 5168 from 5309, we get 141.
Fetch the next digit (6) from the dividend, attach it to 141 and continue: 1416 / 646

Let's proceed to step 5:
646 goes into 1416 2 times with a remainder of 124.
Write down 2 as next digit of the result. 
Result so far: 82.0
Subtract 1292 from 1416 to get 124.
Include the next digit (6) from the dividend after 124, then repeat: 1246 / 646

Let's proceed to step 6:
646 goes into 1246 1 times with a remainder of 600.
Write down 1 as next digit of the result. 
Result so far: 821.0
The remainder is 600 after subtracting 646 from 1246.
Bring next digit (9) of the dividend behind the 600 and repeat the process: 6009 / 646

Going ahead to step 7:
646 goes into 6009 9 times with a remainder of 195.
Use 9 as the next digit of our solution. 
Result so far: 8219.0
If we take 5814 away from 6009, we end up with 195.
Grab the next digit (2) from the dividend, add it to 195, then carry on: 1952 / 646

Let's proceed to step 8:
646 can be fit into 1952 3 times, resulting in a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 82193.0
Deduct 1938 from 1952 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 9:
When dividing 140 by 646, we get 0 with a remainder of 140.
Put 0 as the next digit of the answer. 
Result so far: 82193.0
Deduct 0 from 140 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 10:
646 can be fit into 1400 2 times, resulting in a remainder of 108.
Record the quotient 2 as the next digit in the result. 
Result so far: 82193.02
If we subtract 1292 from 1400, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Moving on to step 11:
646 goes into 1080 1 times with a remainder of 434.
The next digit of our result is 1. 
Result so far: 82193.021
If we subtract 646 from 1080, we get 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Let's proceed to step 12:
646 goes into 4340 6 times with a remainder of 464.
The number 6 becomes the next digit in our result. 
Result so far: 82193.0216
Deduct 3876 from 4340 and we're left with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Step 13:
If we divide 4640 by 646, we get 7 and a remainder of 118.
The next digit of our result is 7. 
Result so far: 82193.02167
Subtract 4522 from 4640 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Let's proceed to step 14:
646 goes into 1180 1 times with a remainder of 534.
Write down 1 as next digit of the result. 
Result so far: 82193.021671
The remainder is 534 after subtracting 646 from 1180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Advancing to step 15:
646 goes into 5340 8 times with a remainder of 172.
Record the quotient 8 as the next digit in the result. 
Result so far: 82193.0216718
If we take 5168 away from 5340, we end up with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Moving on to step 16:
When dividing 1720 by 646, we get 2 with a remainder of 428.
The number 2 becomes the next digit in our result. 
Result so far: 82193.02167182
If we take 1292 away from 1720, we end up with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

In conclusion, the division gives 82193.02167182 with a balance of 4.28e-07.
