We divide 400257 by 37
The aim is to understand the frequency of 37 in 400257.

Advancing to step 1:
4 divided by 37 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 37

Step 2:
37 can be fit into 40 1 times, resulting in a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 37 from 40 and we're left with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 37

Let's proceed to step 3:
37 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 30 after subtracting 0 from 30.
Take the next digit (2) from the dividend and append it to 30, then repeat: 302 / 37

Moving on to step 4:
The number 37 fits into 302 8 times, leaving a remainder of 6.
The next digit of our result is 8. 
Result so far: 108.0
If we subtract 296 from 302, we get 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 37

On to step 5:
When dividing 65 by 37, we get 1 with a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 1081.0
If we take 37 away from 65, we end up with 28.
Include the next digit (7) from the dividend after 28, then repeat: 287 / 37

Step 6:
When dividing 287 by 37, we get 7 with a remainder of 28.
The next digit of our result is 7. 
Result so far: 10817.0
If we subtract 259 from 287, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 7:
37 goes into 280 7 times with a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 10817.7
Deduct 259 from 280 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 8:
The number 37 fits into 210 5 times, leaving a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 10817.75
Deduct 185 from 210 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 9:
If we divide 250 by 37, we get 6 and a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 10817.756
If we subtract 222 from 250, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 10:
37 can be fit into 280 7 times, resulting in a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 10817.7567
Subtracting 259 from 280 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 11:
If we divide 210 by 37, we get 5 and a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 10817.75675
Subtract 185 from 210 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 12:
If we divide 250 by 37, we get 6 and a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 10817.756756
Deduct 222 from 250 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 13:
If we divide 280 by 37, we get 7 and a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 10817.7567567
If we take 259 away from 280, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 14:
If we divide 210 by 37, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 10817.75675675
Subtracting 185 from 210 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

In conclusion, the division gives 10817.75675675 with a balance of 2.5e-08.
