Let's divide 81993017 by 37
The aim is to understand the frequency of 37 in 81993017.

Let's proceed to step 1:
When dividing 8 by 37, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 37

On to step 2:
81 divided by 37 is 2 with a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 74 from 81, we get 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 37

Going ahead to step 3:
37 can be fit into 79 2 times, resulting in a remainder of 5.
The next digit of our result is 2. 
Result so far: 22.0
Subtracting 74 from 79 leaves us with 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 37

Step 4:
When dividing 59 by 37, we get 1 with a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 221.0
Deduct 37 from 59 and we're left with 22.
Bring next digit (3) of the dividend behind the 22 and repeat the process: 223 / 37

Step 5:
37 goes into 223 6 times with a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 2216.0
Subtracting 222 from 223 leaves us with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 37

Going ahead to step 6:
10 divided by 37 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 22160.0
Subtract 0 from 10 to get 10.
Grab the next digit (1) from the dividend, add it to 10, then carry on: 101 / 37

Going ahead to step 7:
The number 37 fits into 101 2 times, leaving a remainder of 27.
Put 2 as the next digit of the answer. 
Result so far: 221602.0
Subtracting 74 from 101 leaves us with 27.
Grab the next digit (7) from the dividend, add it to 27, then carry on: 277 / 37

Step 8:
If we divide 277 by 37, we get 7 and a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 2216027.0
Deduct 259 from 277 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 9:
If we divide 180 by 37, we get 4 and a remainder of 32.
The next digit of our result is 4. 
Result so far: 2216027.4
If we subtract 148 from 180, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 10:
37 goes into 320 8 times with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 2216027.48
Subtract 296 from 320 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
37 can be fit into 240 6 times, resulting in a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 2216027.486
The remainder is 18 after subtracting 222 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 12:
If we divide 180 by 37, we get 4 and a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 2216027.4864
If we take 148 away from 180, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 13:
37 goes into 320 8 times with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 2216027.48648
Subtracting 296 from 320 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 14:
When dividing 240 by 37, we get 6 with a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 2216027.486486
Deduct 222 from 240 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 15:
180 divided by 37 is 4 with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 2216027.4864864
Subtracting 148 from 180 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 16:
37 can be fit into 320 8 times, resulting in a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 2216027.48648648
Deduct 296 from 320 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 2216027.48648648 with a remainder of 2.4e-08.
