We look at the division of 68091246 by 641 
The aim is to understand the frequency of 641 in 68091246.

Step 1:
When dividing 6 by 641, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 641

Moving on to step 2:
When dividing 68 by 641, we get 0 with a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Bring next digit (0) of the dividend behind the 68 and repeat the process: 680 / 641

Let's proceed to step 3:
680 divided by 641 is 1 with a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 641 from 680 and we're left with 39.
Bring next digit (9) of the dividend behind the 39 and repeat the process: 399 / 641

Going ahead to step 4:
If we divide 399 by 641, we get 0 and a remainder of 399.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 399 to get 399.
Include the next digit (1) from the dividend after 399, then repeat: 3991 / 641

Step 5:
If we divide 3991 by 641, we get 6 and a remainder of 145.
Record the quotient 6 as the next digit in the result. 
Result so far: 106.0
If we take 3846 away from 3991, we end up with 145.
Append the next digit (2) from the dividend to 145 and continue with: 1452 / 641

Step 6:
641 can be fit into 1452 2 times, resulting in a remainder of 170.
Put 2 as the next digit of the answer. 
Result so far: 1062.0
Subtract 1282 from 1452 to get 170.
Bring next digit (4) of the dividend behind the 170 and repeat the process: 1704 / 641

Going ahead to step 7:
641 can be fit into 1704 2 times, resulting in a remainder of 422.
Put 2 as the next digit of the answer. 
Result so far: 10622.0
If we take 1282 away from 1704, we end up with 422.
Take the next digit (6) from the dividend and append it to 422, then repeat: 4226 / 641

On to step 8:
641 can be fit into 4226 6 times, resulting in a remainder of 380.
Write down 6 as next digit of the result. 
Result so far: 106226.0
Subtract 3846 from 4226 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 9:
641 can be fit into 3800 5 times, resulting in a remainder of 595.
The next digit of our result is 5. 
Result so far: 106226.5
If we take 3205 away from 3800, we end up with 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

Going ahead to step 10:
641 can be fit into 5950 9 times, resulting in a remainder of 181.
Use 9 as the next digit of our solution. 
Result so far: 106226.59
Subtract 5769 from 5950 to get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

On to step 11:
641 goes into 1810 2 times with a remainder of 528.
Put 2 as the next digit of the answer. 
Result so far: 106226.592
Subtract 1282 from 1810 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.

Let's proceed to step 12:
When dividing 5280 by 641, we get 8 with a remainder of 152.
The next digit of our result is 8. 
Result so far: 106226.5928
The remainder is 152 after subtracting 5128 from 5280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Let's proceed to step 13:
641 goes into 1520 2 times with a remainder of 238.
Put 2 as the next digit of the answer. 
Result so far: 106226.59282
Subtract 1282 from 1520 to get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Let's proceed to step 14:
When dividing 2380 by 641, we get 3 with a remainder of 457.
Write down 3 as next digit of the result. 
Result so far: 106226.592823
If we take 1923 away from 2380, we end up with 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

On to step 15:
If we divide 4570 by 641, we get 7 and a remainder of 83.
Put 7 as the next digit of the answer. 
Result so far: 106226.5928237
The remainder is 83 after subtracting 4487 from 4570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Let's proceed to step 16:
830 divided by 641 is 1 with a remainder of 189.
Use 1 as the next digit of our solution. 
Result so far: 106226.59282371
If we subtract 641 from 830, we get 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

The quotient of the division is 106226.59282371, and the remainder is 1.89e-07.
