86418466 ÷ 191 
We want to figure out the number of times 86418466 can be divided by 191.

On to step 1:
8 divided by 191 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 191

Going ahead to step 2:
When dividing 86 by 191, we get 0 with a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Bring next digit (4) of the dividend behind the 86 and repeat the process: 864 / 191

Going ahead to step 3:
191 can be fit into 864 4 times, resulting in a remainder of 100.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 764 from 864 and we're left with 100.
Include the next digit (1) from the dividend after 100, then repeat: 1001 / 191

Moving on to step 4:
191 goes into 1001 5 times with a remainder of 46.
Write down 5 as next digit of the result. 
Result so far: 45.0
If we subtract 955 from 1001, we get 46.
Grab the next digit (8) from the dividend, add it to 46, then carry on: 468 / 191

Let's proceed to step 5:
When dividing 468 by 191, we get 2 with a remainder of 86.
The number 2 becomes the next digit in our result. 
Result so far: 452.0
Deduct 382 from 468 and we're left with 86.
Include the next digit (4) from the dividend after 86, then repeat: 864 / 191

Step 6:
191 goes into 864 4 times with a remainder of 100.
Write down 4 as next digit of the result. 
Result so far: 4524.0
The remainder is 100 after subtracting 764 from 864.
Bring next digit (6) of the dividend behind the 100 and repeat the process: 1006 / 191

Let's proceed to step 7:
1006 divided by 191 is 5 with a remainder of 51.
The number 5 becomes the next digit in our result. 
Result so far: 45245.0
The remainder is 51 after subtracting 955 from 1006.
Take the next digit (6) from the dividend and append it to 51, then repeat: 516 / 191

Moving on to step 8:
516 divided by 191 is 2 with a remainder of 134.
Use 2 as the next digit of our solution. 
Result so far: 452452.0
If we subtract 382 from 516, we get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Advancing to step 9:
The number 191 fits into 1340 7 times, leaving a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 452452.7
Subtract 1337 from 1340 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 10:
When dividing 30 by 191, we get 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 452452.7
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
The number 191 fits into 300 1 times, leaving a remainder of 109.
Record the quotient 1 as the next digit in the result. 
Result so far: 452452.701
The remainder is 109 after subtracting 191 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Advancing to step 12:
191 can be fit into 1090 5 times, resulting in a remainder of 135.
Write down 5 as next digit of the result. 
Result so far: 452452.7015
Deduct 955 from 1090 and we're left with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

On to step 13:
If we divide 1350 by 191, we get 7 and a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 452452.70157
Deduct 1337 from 1350 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 14:
If we divide 130 by 191, we get 0 and a remainder of 130.
Record the quotient 0 as the next digit in the result. 
Result so far: 452452.70157
If we subtract 0 from 130, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 15:
When dividing 1300 by 191, we get 6 with a remainder of 154.
The next digit of our result is 6. 
Result so far: 452452.7015706
The remainder is 154 after subtracting 1146 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

On to step 16:
191 can be fit into 1540 8 times, resulting in a remainder of 12.
The next digit of our result is 8. 
Result so far: 452452.70157068
Subtract 1528 from 1540 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 452452.70157068 with a remainder of 1.2e-08.
