555990 divided by 37 
The aim is to understand the frequency of 37 in 555990.

Advancing to step 1:
When dividing 5 by 37, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 37

Step 2:
The number 37 fits into 55 1 times, leaving a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 37 from 55 and we're left with 18.
Grab the next digit (5) from the dividend, add it to 18, then carry on: 185 / 37

Moving on to step 3:
37 goes into 185 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 15.0
Deduct 185 from 185 and we're left with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 37

Going ahead to step 4:
If we divide 9 by 37, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 150.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 37

On to step 5:
99 divided by 37 is 2 with a remainder of 25.
Put 2 as the next digit of the answer. 
Result so far: 1502.0
Deduct 74 from 99 and we're left with 25.
Append the next digit (0) from the dividend to 25 and continue with: 250 / 37

Advancing to step 6:
When dividing 250 by 37, we get 6 with a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 15026.0
If we take 222 away from 250, we end up 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.

Moving on to step 7:
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: 15026.7
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.

Moving on to step 8:
37 goes into 210 5 times with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 15026.75
If we subtract 185 from 210, we 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.

Step 9:
37 can be fit into 250 6 times, resulting in a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 15026.756
The remainder is 28 after subtracting 222 from 250.
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 10:
280 divided by 37 is 7 with a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 15026.7567
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.

Step 11:
37 goes into 210 5 times with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 15026.75675
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.

Going ahead to step 12:
37 goes into 250 6 times with a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 15026.756756
Subtracting 222 from 250 leaves us 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.

Step 13:
The number 37 fits into 280 7 times, leaving a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 15026.7567567
The remainder is 21 after subtracting 259 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 14:
When dividing 210 by 37, we get 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 15026.75675675
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.

The quotient of the division is 15026.75675675, and the remainder is 2.5e-08.
