Let's divide 129855 by 37
We're looking to find how many times 37 goes into 129855.

On to step 1:
1 divided by 37 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
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

Let's proceed to step 2:
When dividing 12 by 37, we get 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 37

Advancing to step 3:
When dividing 129 by 37, we get 3 with a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 111 from 129 leaves us with 18.
Fetch the next digit (8) from the dividend, attach it to 18 and continue: 188 / 37

Advancing to step 4:
When dividing 188 by 37, we get 5 with a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
Subtracting 185 from 188 leaves us with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 37

Let's proceed to step 5:
37 goes into 35 0 times with a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 350.0
If we subtract 0 from 35, we get 35.
Append the next digit (5) from the dividend to 35 and continue with: 355 / 37

Going ahead to step 6:
If we divide 355 by 37, we get 9 and a remainder of 22.
The next digit of our result is 9. 
Result so far: 3509.0
If we subtract 333 from 355, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 7:
If we divide 220 by 37, we get 5 and a remainder of 35.
The next digit of our result is 5. 
Result so far: 3509.5
If we take 185 away from 220, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 8:
The number 37 fits into 350 9 times, leaving a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 3509.59
If we take 333 away from 350, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 9:
37 can be fit into 170 4 times, resulting in a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 3509.594
Subtracting 148 from 170 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 10:
37 goes into 220 5 times with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 3509.5945
If we take 185 away from 220, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 11:
The number 37 fits into 350 9 times, leaving a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 3509.59459
Subtracting 333 from 350 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 12:
170 divided by 37 is 4 with a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 3509.594594
If we take 148 away from 170, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 13:
When dividing 220 by 37, we get 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 3509.5945945
Subtract 185 from 220 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 14:
37 can be fit into 350 9 times, resulting in a remainder of 17.
The next digit of our result is 9. 
Result so far: 3509.59459459
Deduct 333 from 350 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

In conclusion, the division gives 3509.59459459 with a balance of 1.7e-08.
