We divide 1891343 by 991
We want to figure out the number of times 1891343 can be divided by 991.

Going ahead to step 1:
The number 991 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 991

Let's proceed to step 2:
991 can be fit into 18 0 times, resulting in a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Include the next digit (9) from the dividend after 18, then repeat: 189 / 991

Going ahead to step 3:
991 goes into 189 0 times with a remainder of 189.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 189 to get 189.
Include the next digit (1) from the dividend after 189, then repeat: 1891 / 991

Moving on to step 4:
The number 991 fits into 1891 1 times, leaving a remainder of 900.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 991 away from 1891, we end up with 900.
Include the next digit (3) from the dividend after 900, then repeat: 9003 / 991

On to step 5:
The number 991 fits into 9003 9 times, leaving a remainder of 84.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
The remainder is 84 after subtracting 8919 from 9003.
Grab the next digit (4) from the dividend, add it to 84, then carry on: 844 / 991

On to step 6:
If we divide 844 by 991, we get 0 and a remainder of 844.
Record the quotient 0 as the next digit in the result. 
Result so far: 190.0
Deduct 0 from 844 and we're left with 844.
Append the next digit (3) from the dividend to 844 and continue with: 8443 / 991

On to step 7:
991 goes into 8443 8 times with a remainder of 515.
Record the quotient 8 as the next digit in the result. 
Result so far: 1908.0
If we subtract 7928 from 8443, we get 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Advancing to step 8:
The number 991 fits into 5150 5 times, leaving a remainder of 195.
Use 5 as the next digit of our solution. 
Result so far: 1908.5
The remainder is 195 after subtracting 4955 from 5150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Let's proceed to step 9:
991 goes into 1950 1 times with a remainder of 959.
The next digit of our result is 1. 
Result so far: 1908.51
The remainder is 959 after subtracting 991 from 1950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9590, and continue the process.

Going ahead to step 10:
991 goes into 9590 9 times with a remainder of 671.
Use 9 as the next digit of our solution. 
Result so far: 1908.519
If we subtract 8919 from 9590, we get 671.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6710, and continue the process.

On to step 11:
The number 991 fits into 6710 6 times, leaving a remainder of 764.
The next digit of our result is 6. 
Result so far: 1908.5196
Subtracting 5946 from 6710 leaves us with 764.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7640, and continue the process.

Step 12:
991 goes into 7640 7 times with a remainder of 703.
Record the quotient 7 as the next digit in the result. 
Result so far: 1908.51967
Subtracting 6937 from 7640 leaves us with 703.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7030, and continue the process.

Advancing to step 13:
When dividing 7030 by 991, we get 7 with a remainder of 93.
The number 7 becomes the next digit in our result. 
Result so far: 1908.519677
Deduct 6937 from 7030 and we're left with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

After the division, we end up with 1908.519677 and a remainder of 9.3e-06.
