Let's divide 431821 by 37
The aim is to understand the frequency of 37 in 431821.

Let's proceed to step 1:
When dividing 4 by 37, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 37

Advancing to step 2:
37 goes into 43 1 times with a remainder of 6.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 37 from 43 leaves us with 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 37

Let's proceed to step 3:
The number 37 fits into 61 1 times, leaving a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we subtract 37 from 61, we get 24.
Take the next digit (8) from the dividend and append it to 24, then repeat: 248 / 37

On to step 4:
37 goes into 248 6 times with a remainder of 26.
Record the quotient 6 as the next digit in the result. 
Result so far: 116.0
Deduct 222 from 248 and we're left with 26.
Include the next digit (2) from the dividend after 26, then repeat: 262 / 37

Advancing to step 5:
262 divided by 37 is 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 1167.0
If we take 259 away from 262, we end up with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 37

Advancing to step 6:
The number 37 fits into 31 0 times, leaving a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 11670.0
The remainder is 31 after subtracting 0 from 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 7:
310 divided by 37 is 8 with a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 11670.8
If we take 296 away from 310, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
When dividing 140 by 37, we get 3 with a remainder of 29.
The next digit of our result is 3. 
Result so far: 11670.83
Subtract 111 from 140 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 9:
The number 37 fits into 290 7 times, leaving a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 11670.837
Subtract 259 from 290 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 10:
When dividing 310 by 37, we get 8 with a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 11670.8378
Deduct 296 from 310 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 11:
140 divided by 37 is 3 with a remainder of 29.
Write down 3 as next digit of the result. 
Result so far: 11670.83783
Subtracting 111 from 140 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 12:
37 can be fit into 290 7 times, resulting in a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 11670.837837
If we subtract 259 from 290, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 13:
The number 37 fits into 310 8 times, leaving a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 11670.8378378
Subtracting 296 from 310 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 14:
When dividing 140 by 37, we get 3 with a remainder of 29.
The next digit of our result is 3. 
Result so far: 11670.83783783
Subtracting 111 from 140 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final outcome is 11670.83783783, with a leftover of 2.9e-08.
