We divide 168621 by 37
The aim is to understand the frequency of 37 in 168621.

Advancing to step 1:
37 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 37

Going ahead to step 2:
37 can be fit into 16 0 times, resulting in a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 37

Going ahead to step 3:
When dividing 168 by 37, we get 4 with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 148 away from 168, we end up with 20.
Bring next digit (6) of the dividend behind the 20 and repeat the process: 206 / 37

On to step 4:
When dividing 206 by 37, we get 5 with a remainder of 21.
Put 5 as the next digit of the answer. 
Result so far: 45.0
Subtracting 185 from 206 leaves us with 21.
Fetch the next digit (2) from the dividend, attach it to 21 and continue: 212 / 37

On to step 5:
37 goes into 212 5 times with a remainder of 27.
Put 5 as the next digit of the answer. 
Result so far: 455.0
Subtract 185 from 212 to get 27.
Fetch the next digit (1) from the dividend, attach it to 27 and continue: 271 / 37

Going ahead to step 6:
When dividing 271 by 37, we get 7 with a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 4557.0
Subtract 259 from 271 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
120 divided by 37 is 3 with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 4557.3
If we take 111 away from 120, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 8:
When dividing 90 by 37, we get 2 with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 4557.32
If we take 74 away from 90, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
When dividing 160 by 37, we get 4 with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 4557.324
The remainder is 12 after subtracting 148 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
When dividing 120 by 37, we get 3 with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 4557.3243
The remainder is 9 after subtracting 111 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 11:
If we divide 90 by 37, we get 2 and a remainder of 16.
The next digit of our result is 2. 
Result so far: 4557.32432
If we take 74 away from 90, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 12:
160 divided by 37 is 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 4557.324324
Subtracting 148 from 160 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 13:
When dividing 120 by 37, we get 3 with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 4557.3243243
If we subtract 111 from 120, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 14:
90 divided by 37 is 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 4557.32432432
If we subtract 74 from 90, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 4557.32432432 with a balance of 1.6e-08.
