We divide 21571952 by 673
The aim is to understand the frequency of 673 in 21571952.

Advancing to step 1:
673 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 673

Let's proceed to step 2:
673 can be fit into 21 0 times, resulting in a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 673

On to step 3:
673 can be fit into 215 0 times, resulting in a remainder of 215.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 215 to get 215.
Take the next digit (7) from the dividend and append it to 215, then repeat: 2157 / 673

Advancing to step 4:
The number 673 fits into 2157 3 times, leaving a remainder of 138.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 138 after subtracting 2019 from 2157.
Append the next digit (1) from the dividend to 138 and continue with: 1381 / 673

Step 5:
1381 divided by 673 is 2 with a remainder of 35.
Use 2 as the next digit of our solution. 
Result so far: 32.0
Subtract 1346 from 1381 to get 35.
Include the next digit (9) from the dividend after 35, then repeat: 359 / 673

On to step 6:
When dividing 359 by 673, we get 0 with a remainder of 359.
Record the quotient 0 as the next digit in the result. 
Result so far: 320.0
If we take 0 away from 359, we end up with 359.
Fetch the next digit (5) from the dividend, attach it to 359 and continue: 3595 / 673

Let's proceed to step 7:
673 goes into 3595 5 times with a remainder of 230.
The next digit of our result is 5. 
Result so far: 3205.0
The remainder is 230 after subtracting 3365 from 3595.
Take the next digit (2) from the dividend and append it to 230, then repeat: 2302 / 673

On to step 8:
If we divide 2302 by 673, we get 3 and a remainder of 283.
Use 3 as the next digit of our solution. 
Result so far: 32053.0
If we subtract 2019 from 2302, we get 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Step 9:
The number 673 fits into 2830 4 times, leaving a remainder of 138.
Record the quotient 4 as the next digit in the result. 
Result so far: 32053.4
If we take 2692 away from 2830, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Let's proceed to step 10:
673 goes into 1380 2 times with a remainder of 34.
Put 2 as the next digit of the answer. 
Result so far: 32053.42
Subtracting 1346 from 1380 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 11:
673 can be fit into 340 0 times, resulting in a remainder of 340.
The number 0 becomes the next digit in our result. 
Result so far: 32053.42
Deduct 0 from 340 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 12:
673 goes into 3400 5 times with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 32053.4205
Deduct 3365 from 3400 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 13:
673 goes into 350 0 times with a remainder of 350.
The number 0 becomes the next digit in our result. 
Result so far: 32053.4205
The remainder is 350 after subtracting 0 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 14:
When dividing 3500 by 673, we get 5 with a remainder of 135.
Record the quotient 5 as the next digit in the result. 
Result so far: 32053.420505
If we take 3365 away from 3500, we end up with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Going ahead to step 15:
If we divide 1350 by 673, we get 2 and a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 32053.4205052
Subtract 1346 from 1350 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 16:
673 can be fit into 40 0 times, resulting in a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 32053.4205052
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 32053.4205052 and a remainder of 4e-08.
