We divide 57191493 by 641
The aim is to understand the frequency of 641 in 57191493.

On to step 1:
641 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 641

Let's proceed to step 2:
If we divide 57 by 641, we get 0 and a remainder of 57.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 57 after subtracting 0 from 57.
Include the next digit (1) from the dividend after 57, then repeat: 571 / 641

Step 3:
When dividing 571 by 641, we get 0 with a remainder of 571.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 571, we get 571.
Fetch the next digit (9) from the dividend, attach it to 571 and continue: 5719 / 641

Moving on to step 4:
The number 641 fits into 5719 8 times, leaving a remainder of 591.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 5128 from 5719 leaves us with 591.
Append the next digit (1) from the dividend to 591 and continue with: 5911 / 641

Let's proceed to step 5:
641 can be fit into 5911 9 times, resulting in a remainder of 142.
The next digit of our result is 9. 
Result so far: 89.0
If we take 5769 away from 5911, we end up with 142.
Include the next digit (4) from the dividend after 142, then repeat: 1424 / 641

Step 6:
641 can be fit into 1424 2 times, resulting in a remainder of 142.
Put 2 as the next digit of the answer. 
Result so far: 892.0
Subtracting 1282 from 1424 leaves us with 142.
Fetch the next digit (9) from the dividend, attach it to 142 and continue: 1429 / 641

Advancing to step 7:
1429 divided by 641 is 2 with a remainder of 147.
The number 2 becomes the next digit in our result. 
Result so far: 8922.0
Subtracting 1282 from 1429 leaves us with 147.
Bring next digit (3) of the dividend behind the 147 and repeat the process: 1473 / 641

On to step 8:
If we divide 1473 by 641, we get 2 and a remainder of 191.
The next digit of our result is 2. 
Result so far: 89222.0
If we subtract 1282 from 1473, we get 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Advancing to step 9:
When dividing 1910 by 641, we get 2 with a remainder of 628.
Use 2 as the next digit of our solution. 
Result so far: 89222.2
Subtract 1282 from 1910 to get 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Step 10:
641 can be fit into 6280 9 times, resulting in a remainder of 511.
Record the quotient 9 as the next digit in the result. 
Result so far: 89222.29
If we take 5769 away from 6280, we end up with 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

Going ahead to step 11:
The number 641 fits into 5110 7 times, leaving a remainder of 623.
The number 7 becomes the next digit in our result. 
Result so far: 89222.297
If we take 4487 away from 5110, we end up with 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

Let's proceed to step 12:
When dividing 6230 by 641, we get 9 with a remainder of 461.
Write down 9 as next digit of the result. 
Result so far: 89222.2979
If we subtract 5769 from 6230, we get 461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

Advancing to step 13:
The number 641 fits into 4610 7 times, leaving a remainder of 123.
Use 7 as the next digit of our solution. 
Result so far: 89222.29797
Deduct 4487 from 4610 and we're left with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Moving on to step 14:
1230 divided by 641 is 1 with a remainder of 589.
Write down 1 as next digit of the result. 
Result so far: 89222.297971
Subtracting 641 from 1230 leaves us with 589.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5890, and continue the process.

Advancing to step 15:
641 goes into 5890 9 times with a remainder of 121.
The next digit of our result is 9. 
Result so far: 89222.2979719
Deduct 5769 from 5890 and we're left with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

On to step 16:
If we divide 1210 by 641, we get 1 and a remainder of 569.
Put 1 as the next digit of the answer. 
Result so far: 89222.29797191
Subtracting 641 from 1210 leaves us with 569.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5690, and continue the process.

After the division, we end up with 89222.29797191 and a remainder of 5.69e-07.
