121948 ÷ 37 
The aim is to understand the frequency of 37 in 121948.

Moving on to step 1:
If we divide 1 by 37, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 37

Moving on to step 2:
When dividing 12 by 37, we get 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 37

On to step 3:
The number 37 fits into 121 3 times, leaving a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 111 from 121 leaves us with 10.
Take the next digit (9) from the dividend and append it to 10, then repeat: 109 / 37

Advancing to step 4:
When dividing 109 by 37, we get 2 with a remainder of 35.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
The remainder is 35 after subtracting 74 from 109.
Bring next digit (4) of the dividend behind the 35 and repeat the process: 354 / 37

Advancing to step 5:
37 goes into 354 9 times with a remainder of 21.
The next digit of our result is 9. 
Result so far: 329.0
If we take 333 away from 354, we end up with 21.
Fetch the next digit (8) from the dividend, attach it to 21 and continue: 218 / 37

Let's proceed to step 6:
218 divided by 37 is 5 with a remainder of 33.
The number 5 becomes the next digit in our result. 
Result so far: 3295.0
The remainder is 33 after subtracting 185 from 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 7:
37 can be fit into 330 8 times, resulting in a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 3295.8
The remainder is 34 after subtracting 296 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 8:
When dividing 340 by 37, we get 9 with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 3295.89
Subtract 333 from 340 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 9:
70 divided by 37 is 1 with a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 3295.891
The remainder is 33 after subtracting 37 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 10:
When dividing 330 by 37, we get 8 with a remainder of 34.
The next digit of our result is 8. 
Result so far: 3295.8918
The remainder is 34 after subtracting 296 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 11:
The number 37 fits into 340 9 times, leaving a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 3295.89189
Deduct 333 from 340 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 12:
When dividing 70 by 37, we get 1 with a remainder of 33.
Use 1 as the next digit of our solution. 
Result so far: 3295.891891
Deduct 37 from 70 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 13:
The number 37 fits into 330 8 times, leaving a remainder of 34.
Write down 8 as next digit of the result. 
Result so far: 3295.8918918
If we take 296 away from 330, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 14:
The number 37 fits into 340 9 times, leaving a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 3295.89189189
Subtracting 333 from 340 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

In conclusion, the division gives 3295.89189189 with a balance of 7e-09.
