We're dividing 72140631 by 186 
We want to figure out the number of times 72140631 can be divided by 186.

Step 1:
7 divided by 186 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 186

Going ahead to step 2:
If we divide 72 by 186, we get 0 and a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Fetch the next digit (1) from the dividend, attach it to 72 and continue: 721 / 186

Let's proceed to step 3:
When dividing 721 by 186, we get 3 with a remainder of 163.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 558 from 721 leaves us with 163.
Bring next digit (4) of the dividend behind the 163 and repeat the process: 1634 / 186

Let's proceed to step 4:
If we divide 1634 by 186, we get 8 and a remainder of 146.
Write down 8 as next digit of the result. 
Result so far: 38.0
Deduct 1488 from 1634 and we're left with 146.
Take the next digit (0) from the dividend and append it to 146, then repeat: 1460 / 186

Step 5:
1460 divided by 186 is 7 with a remainder of 158.
Put 7 as the next digit of the answer. 
Result so far: 387.0
If we subtract 1302 from 1460, we get 158.
Fetch the next digit (6) from the dividend, attach it to 158 and continue: 1586 / 186

Step 6:
186 goes into 1586 8 times with a remainder of 98.
Put 8 as the next digit of the answer. 
Result so far: 3878.0
Subtract 1488 from 1586 to get 98.
Append the next digit (3) from the dividend to 98 and continue with: 983 / 186

On to step 7:
The number 186 fits into 983 5 times, leaving a remainder of 53.
The number 5 becomes the next digit in our result. 
Result so far: 38785.0
Subtract 930 from 983 to get 53.
Bring next digit (1) of the dividend behind the 53 and repeat the process: 531 / 186

Step 8:
186 can be fit into 531 2 times, resulting in a remainder of 159.
Use 2 as the next digit of our solution. 
Result so far: 387852.0
If we take 372 away from 531, we end up with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Step 9:
If we divide 1590 by 186, we get 8 and a remainder of 102.
The number 8 becomes the next digit in our result. 
Result so far: 387852.8
If we take 1488 away from 1590, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Step 10:
The number 186 fits into 1020 5 times, leaving a remainder of 90.
Write down 5 as next digit of the result. 
Result so far: 387852.85
If we take 930 away from 1020, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 11:
The number 186 fits into 900 4 times, leaving a remainder of 156.
Record the quotient 4 as the next digit in the result. 
Result so far: 387852.854
Deduct 744 from 900 and we're left with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Going ahead to step 12:
186 goes into 1560 8 times with a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 387852.8548
If we take 1488 away from 1560, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 13:
If we divide 720 by 186, we get 3 and a remainder of 162.
Use 3 as the next digit of our solution. 
Result so far: 387852.85483
If we take 558 away from 720, we end up with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Moving on to step 14:
If we divide 1620 by 186, we get 8 and a remainder of 132.
Write down 8 as next digit of the result. 
Result so far: 387852.854838
Subtract 1488 from 1620 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Advancing to step 15:
When dividing 1320 by 186, we get 7 with a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 387852.8548387
Subtract 1302 from 1320 to 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.

Let's proceed to step 16:
180 divided by 186 is 0 with a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 387852.8548387
Subtract 0 from 180 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

The final result is 387852.8548387 with a remainder of 1.8e-07.
