989980 divided by 37 
The aim is to understand the frequency of 37 in 989980.

Step 1:
The number 37 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 37

On to step 2:
The number 37 fits into 98 2 times, leaving a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 74 from 98 and we're left with 24.
Include the next digit (9) from the dividend after 24, then repeat: 249 / 37

Moving on to step 3:
249 divided by 37 is 6 with a remainder of 27.
Write down 6 as next digit of the result. 
Result so far: 26.0
If we subtract 222 from 249, we get 27.
Take the next digit (9) from the dividend and append it to 27, then repeat: 279 / 37

Let's proceed to step 4:
37 goes into 279 7 times with a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 267.0
Deduct 259 from 279 and we're left with 20.
Grab the next digit (8) from the dividend, add it to 20, then carry on: 208 / 37

Moving on to step 5:
37 can be fit into 208 5 times, resulting in a remainder of 23.
The number 5 becomes the next digit in our result. 
Result so far: 2675.0
Subtract 185 from 208 to get 23.
Append the next digit (0) from the dividend to 23 and continue with: 230 / 37

Step 6:
230 divided by 37 is 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 26756.0
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.

Going ahead to step 7:
The number 37 fits into 80 2 times, leaving a remainder of 6.
The next digit of our result is 2. 
Result so far: 26756.2
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 8:
When dividing 60 by 37, we get 1 with a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 26756.21
Deduct 37 from 60 and we're left 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 9:
The number 37 fits into 230 6 times, leaving a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 26756.216
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.

On to step 10:
37 can be fit into 80 2 times, resulting in a remainder of 6.
The next digit of our result is 2. 
Result so far: 26756.2162
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.

Let's proceed to step 11:
37 can be fit into 60 1 times, resulting in a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 26756.21621
If we subtract 37 from 60, we 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 12:
37 goes into 230 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 26756.216216
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.

Advancing to step 13:
37 can be fit into 80 2 times, resulting in a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 26756.2162162
The remainder is 6 after subtracting 74 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 14:
37 can be fit into 60 1 times, resulting in a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 26756.21621621
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.

The final outcome is 26756.21621621, with a leftover of 2.3e-08.
