878634 divided by 37 
The aim is to understand the frequency of 37 in 878634.

On to step 1:
When dividing 8 by 37, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 37

Advancing to step 2:
37 goes into 87 2 times with a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 74 away from 87, we end up with 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 37

Going ahead to step 3:
37 can be fit into 138 3 times, resulting in a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 23.0
Subtract 111 from 138 to get 27.
Grab the next digit (6) from the dividend, add it to 27, then carry on: 276 / 37

Step 4:
The number 37 fits into 276 7 times, leaving a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 237.0
The remainder is 17 after subtracting 259 from 276.
Fetch the next digit (3) from the dividend, attach it to 17 and continue: 173 / 37

Moving on to step 5:
When dividing 173 by 37, we get 4 with a remainder of 25.
Record the quotient 4 as the next digit in the result. 
Result so far: 2374.0
Subtracting 148 from 173 leaves us with 25.
Grab the next digit (4) from the dividend, add it to 25, then carry on: 254 / 37

Step 6:
When dividing 254 by 37, we get 6 with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 23746.0
If we subtract 222 from 254, 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.

Moving on to step 7:
37 can be fit into 320 8 times, resulting in a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 23746.8
The remainder is 24 after subtracting 296 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 8:
37 can be fit into 240 6 times, resulting in a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 23746.86
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.

Advancing to step 9:
180 divided by 37 is 4 with a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 23746.864
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.

Moving on to step 10:
If we divide 320 by 37, we get 8 and a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 23746.8648
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.

Step 11:
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: 23746.86486
If we take 222 away from 240, we end up 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.

Going ahead to step 12:
37 can be fit into 180 4 times, resulting in a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 23746.864864
The remainder is 32 after subtracting 148 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 13:
If we divide 320 by 37, we get 8 and a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 23746.8648648
If we take 296 away from 320, we end up 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.

Step 14:
When dividing 240 by 37, we get 6 with a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 23746.86486486
If we subtract 222 from 240, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final result is 23746.86486486 with a remainder of 1.8e-08.
