21670150 ÷ 191 
We want to figure out the number of times 21670150 can be divided by 191.

Advancing to step 1:
The number 191 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 191

On to step 2:
191 goes into 21 0 times with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 191

Step 3:
191 can be fit into 216 1 times, resulting in a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 191 from 216 to get 25.
Append the next digit (7) from the dividend to 25 and continue with: 257 / 191

Step 4:
191 goes into 257 1 times with a remainder of 66.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 191 away from 257, we end up with 66.
Take the next digit (0) from the dividend and append it to 66, then repeat: 660 / 191

Going ahead to step 5:
The number 191 fits into 660 3 times, leaving a remainder of 87.
The next digit of our result is 3. 
Result so far: 113.0
Subtract 573 from 660 to get 87.
Take the next digit (1) from the dividend and append it to 87, then repeat: 871 / 191

Advancing to step 6:
191 can be fit into 871 4 times, resulting in a remainder of 107.
The number 4 becomes the next digit in our result. 
Result so far: 1134.0
Subtracting 764 from 871 leaves us with 107.
Include the next digit (5) from the dividend after 107, then repeat: 1075 / 191

Let's proceed to step 7:
The number 191 fits into 1075 5 times, leaving a remainder of 120.
Use 5 as the next digit of our solution. 
Result so far: 11345.0
Subtracting 955 from 1075 leaves us with 120.
Bring next digit (0) of the dividend behind the 120 and repeat the process: 1200 / 191

On to step 8:
191 can be fit into 1200 6 times, resulting in a remainder of 54.
The next digit of our result is 6. 
Result so far: 113456.0
If we subtract 1146 from 1200, 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.

Let's proceed to step 9:
The number 191 fits into 540 2 times, leaving a remainder of 158.
Record the quotient 2 as the next digit in the result. 
Result so far: 113456.2
If we subtract 382 from 540, we get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Step 10:
191 can be fit into 1580 8 times, resulting in a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 113456.28
The remainder is 52 after subtracting 1528 from 1580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 11:
When dividing 520 by 191, we get 2 with a remainder of 138.
The next digit of our result is 2. 
Result so far: 113456.282
Deduct 382 from 520 and we're left with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Let's proceed to step 12:
191 goes into 1380 7 times with a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 113456.2827
If we subtract 1337 from 1380, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 13:
The number 191 fits into 430 2 times, leaving a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 113456.28272
Subtracting 382 from 430 leaves us 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.

On to step 14:
191 goes into 480 2 times with a remainder of 98.
The next digit of our result is 2. 
Result so far: 113456.282722
If we take 382 away from 480, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

After the division, we end up with 113456.282722 and a remainder of 9.8e-06.
