561239 ÷ 37 
The aim is to understand the frequency of 37 in 561239.

Advancing to step 1:
When dividing 5 by 37, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 37

Moving on to step 2:
When dividing 56 by 37, we get 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 37 from 56 and we're left with 19.
Fetch the next digit (1) from the dividend, attach it to 19 and continue: 191 / 37

Moving on to step 3:
If we divide 191 by 37, we get 5 and a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtract 185 from 191 to get 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 37

Let's proceed to step 4:
The number 37 fits into 62 1 times, leaving a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 151.0
Subtracting 37 from 62 leaves us with 25.
Fetch the next digit (3) from the dividend, attach it to 25 and continue: 253 / 37

Let's proceed to step 5:
37 goes into 253 6 times with a remainder of 31.
The next digit of our result is 6. 
Result so far: 1516.0
Subtracting 222 from 253 leaves us with 31.
Bring next digit (9) of the dividend behind the 31 and repeat the process: 319 / 37

Moving on to step 6:
If we divide 319 by 37, we get 8 and a remainder of 23.
Use 8 as the next digit of our solution. 
Result so far: 15168.0
If we take 296 away from 319, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 7:
230 divided by 37 is 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 15168.6
The remainder is 8 after subtracting 222 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 8:
If we divide 80 by 37, we get 2 and a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 15168.62
If we take 74 away from 80, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
60 divided by 37 is 1 with a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 15168.621
If we take 37 away from 60, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 10:
When dividing 230 by 37, we get 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 15168.6216
Subtract 222 from 230 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 11:
The number 37 fits into 80 2 times, leaving a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 15168.62162
Subtracting 74 from 80 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 12:
37 goes into 60 1 times with a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 15168.621621
Subtract 37 from 60 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 13:
The number 37 fits into 230 6 times, leaving a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 15168.6216216
If we take 222 away from 230, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 14:
When dividing 80 by 37, we get 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 15168.62162162
If we subtract 74 from 80, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The quotient of the division is 15168.62162162, and the remainder is 6e-09.
