We look at the division of 91639312 by 186 
Our goal is to divide 91639312 by 186.

Moving on to step 1:
If we divide 9 by 186, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 186

Let's proceed to step 2:
When dividing 91 by 186, we get 0 with a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Append the next digit (6) from the dividend to 91 and continue with: 916 / 186

Moving on to step 3:
186 goes into 916 4 times with a remainder of 172.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 744 from 916 and we're left with 172.
Bring next digit (3) of the dividend behind the 172 and repeat the process: 1723 / 186

Going ahead to step 4:
If we divide 1723 by 186, we get 9 and a remainder of 49.
Put 9 as the next digit of the answer. 
Result so far: 49.0
Deduct 1674 from 1723 and we're left with 49.
Take the next digit (9) from the dividend and append it to 49, then repeat: 499 / 186

Step 5:
When dividing 499 by 186, we get 2 with a remainder of 127.
Write down 2 as next digit of the result. 
Result so far: 492.0
If we take 372 away from 499, we end up with 127.
Append the next digit (3) from the dividend to 127 and continue with: 1273 / 186

Going ahead to step 6:
186 can be fit into 1273 6 times, resulting in a remainder of 157.
Put 6 as the next digit of the answer. 
Result so far: 4926.0
If we take 1116 away from 1273, we end up with 157.
Grab the next digit (1) from the dividend, add it to 157, then carry on: 1571 / 186

Step 7:
If we divide 1571 by 186, we get 8 and a remainder of 83.
Put 8 as the next digit of the answer. 
Result so far: 49268.0
Subtracting 1488 from 1571 leaves us with 83.
Take the next digit (2) from the dividend and append it to 83, then repeat: 832 / 186

Let's proceed to step 8:
186 can be fit into 832 4 times, resulting in a remainder of 88.
Use 4 as the next digit of our solution. 
Result so far: 492684.0
If we take 744 away from 832, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 9:
186 can be fit into 880 4 times, resulting in a remainder of 136.
Put 4 as the next digit of the answer. 
Result so far: 492684.4
Subtract 744 from 880 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 10:
If we divide 1360 by 186, we get 7 and a remainder of 58.
Write down 7 as next digit of the result. 
Result so far: 492684.47
If we take 1302 away from 1360, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 11:
186 goes into 580 3 times with a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 492684.473
Subtract 558 from 580 to 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.

Moving on to step 12:
186 can be fit into 220 1 times, resulting in a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 492684.4731
The remainder is 34 after subtracting 186 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 13:
If we divide 340 by 186, we get 1 and a remainder of 154.
Put 1 as the next digit of the answer. 
Result so far: 492684.47311
Subtract 186 from 340 to get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

The quotient of the division is 492684.47311, and the remainder is 0.000154.
