We look at the division of 4172940 by 186 
We're looking to find how many times 186 goes into 4172940.

Let's proceed to step 1:
The number 186 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 186

Step 2:
186 goes into 41 0 times with a remainder of 41.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 41, we end up with 41.
Grab the next digit (7) from the dividend, add it to 41, then carry on: 417 / 186

Let's proceed to step 3:
If we divide 417 by 186, we get 2 and a remainder of 45.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 372 from 417 leaves us with 45.
Fetch the next digit (2) from the dividend, attach it to 45 and continue: 452 / 186

Moving on to step 4:
186 goes into 452 2 times with a remainder of 80.
The next digit of our result is 2. 
Result so far: 22.0
Subtracting 372 from 452 leaves us with 80.
Bring next digit (9) of the dividend behind the 80 and repeat the process: 809 / 186

Advancing to step 5:
If we divide 809 by 186, we get 4 and a remainder of 65.
Record the quotient 4 as the next digit in the result. 
Result so far: 224.0
The remainder is 65 after subtracting 744 from 809.
Take the next digit (4) from the dividend and append it to 65, then repeat: 654 / 186

Let's proceed to step 6:
654 divided by 186 is 3 with a remainder of 96.
Record the quotient 3 as the next digit in the result. 
Result so far: 2243.0
If we subtract 558 from 654, we get 96.
Take the next digit (0) from the dividend and append it to 96, then repeat: 960 / 186

Step 7:
186 goes into 960 5 times with a remainder of 30.
The next digit of our result is 5. 
Result so far: 22435.0
Subtract 930 from 960 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
If we divide 300 by 186, we get 1 and a remainder of 114.
The number 1 becomes the next digit in our result. 
Result so far: 22435.1
Subtract 186 from 300 to get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

On to step 9:
186 goes into 1140 6 times with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 22435.16
If we take 1116 away from 1140, 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.

Going ahead to step 10:
The number 186 fits into 240 1 times, leaving a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 22435.161
If we subtract 186 from 240, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 11:
186 can be fit into 540 2 times, resulting in a remainder of 168.
Use 2 as the next digit of our solution. 
Result so far: 22435.1612
If we subtract 372 from 540, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

On to step 12:
186 goes into 1680 9 times with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 22435.16129
If we take 1674 away from 1680, 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 13:
186 can be fit into 60 0 times, resulting in a remainder of 60.
The next digit of our result is 0. 
Result so far: 22435.16129
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 14:
If we divide 600 by 186, we get 3 and a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 22435.1612903
The remainder is 42 after subtracting 558 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 15:
186 can be fit into 420 2 times, resulting in a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 22435.16129032
Deduct 372 from 420 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

In conclusion, the division gives 22435.16129032 with a balance of 4.8e-08.
