We're dividing 21371132 by 674 
The aim is to understand the frequency of 674 in 21371132.

Going ahead to step 1:
When dividing 2 by 674, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 674

Let's proceed to step 2:
When dividing 21 by 674, we get 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Fetch the next digit (3) from the dividend, attach it to 21 and continue: 213 / 674

On to step 3:
If we divide 213 by 674, we get 0 and a remainder of 213.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 213 and we're left with 213.
Take the next digit (7) from the dividend and append it to 213, then repeat: 2137 / 674

Step 4:
The number 674 fits into 2137 3 times, leaving a remainder of 115.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 2022 away from 2137, we end up with 115.
Bring next digit (1) of the dividend behind the 115 and repeat the process: 1151 / 674

On to step 5:
1151 divided by 674 is 1 with a remainder of 477.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
Subtracting 674 from 1151 leaves us with 477.
Bring next digit (1) of the dividend behind the 477 and repeat the process: 4771 / 674

Moving on to step 6:
674 goes into 4771 7 times with a remainder of 53.
Record the quotient 7 as the next digit in the result. 
Result so far: 317.0
Subtract 4718 from 4771 to get 53.
Fetch the next digit (3) from the dividend, attach it to 53 and continue: 533 / 674

Let's proceed to step 7:
If we divide 533 by 674, we get 0 and a remainder of 533.
The number 0 becomes the next digit in our result. 
Result so far: 3170.0
The remainder is 533 after subtracting 0 from 533.
Append the next digit (2) from the dividend to 533 and continue with: 5332 / 674

Let's proceed to step 8:
5332 divided by 674 is 7 with a remainder of 614.
Record the quotient 7 as the next digit in the result. 
Result so far: 31707.0
Deduct 4718 from 5332 and we're left with 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Step 9:
The number 674 fits into 6140 9 times, leaving a remainder of 74.
The number 9 becomes the next digit in our result. 
Result so far: 31707.9
If we subtract 6066 from 6140, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 10:
If we divide 740 by 674, we get 1 and a remainder of 66.
The number 1 becomes the next digit in our result. 
Result so far: 31707.91
If we take 674 away from 740, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 11:
When dividing 660 by 674, we get 0 with a remainder of 660.
Write down 0 as next digit of the result. 
Result so far: 31707.91
If we subtract 0 from 660, we get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

On to step 12:
If we divide 6600 by 674, we get 9 and a remainder of 534.
The number 9 becomes the next digit in our result. 
Result so far: 31707.9109
The remainder is 534 after subtracting 6066 from 6600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Moving on to step 13:
5340 divided by 674 is 7 with a remainder of 622.
The number 7 becomes the next digit in our result. 
Result so far: 31707.91097
Subtracting 4718 from 5340 leaves us with 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

Step 14:
6220 divided by 674 is 9 with a remainder of 154.
Put 9 as the next digit of the answer. 
Result so far: 31707.910979
If we take 6066 away from 6220, we end up with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

On to step 15:
The number 674 fits into 1540 2 times, leaving a remainder of 192.
Use 2 as the next digit of our solution. 
Result so far: 31707.9109792
Subtracting 1348 from 1540 leaves us with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 16:
674 can be fit into 1920 2 times, resulting in a remainder of 572.
Use 2 as the next digit of our solution. 
Result so far: 31707.91097922
If we take 1348 away from 1920, we end up with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

In conclusion, the division gives 31707.91097922 with a balance of 5.72e-07.
