Let's divide 11861903 by 981
We want to figure out the number of times 11861903 can be divided by 981.

Moving on to step 1:
When dividing 1 by 981, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 981

On to step 2:
The number 981 fits into 11 0 times, leaving a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 11, we end up with 11.
Fetch the next digit (8) from the dividend, attach it to 11 and continue: 118 / 981

Advancing to step 3:
981 can be fit into 118 0 times, resulting in a remainder of 118.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 118 and we're left with 118.
Include the next digit (6) from the dividend after 118, then repeat: 1186 / 981

Advancing to step 4:
The number 981 fits into 1186 1 times, leaving a remainder of 205.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 981 from 1186 to get 205.
Take the next digit (1) from the dividend and append it to 205, then repeat: 2051 / 981

Let's proceed to step 5:
2051 divided by 981 is 2 with a remainder of 89.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 1962 from 2051, we get 89.
Bring next digit (9) of the dividend behind the 89 and repeat the process: 899 / 981

Going ahead to step 6:
899 divided by 981 is 0 with a remainder of 899.
Use 0 as the next digit of our solution. 
Result so far: 120.0
If we take 0 away from 899, we end up with 899.
Take the next digit (0) from the dividend and append it to 899, then repeat: 8990 / 981

On to step 7:
981 goes into 8990 9 times with a remainder of 161.
Use 9 as the next digit of our solution. 
Result so far: 1209.0
Deduct 8829 from 8990 and we're left with 161.
Include the next digit (3) from the dividend after 161, then repeat: 1613 / 981

Let's proceed to step 8:
1613 divided by 981 is 1 with a remainder of 632.
Use 1 as the next digit of our solution. 
Result so far: 12091.0
The remainder is 632 after subtracting 981 from 1613.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Going ahead to step 9:
981 can be fit into 6320 6 times, resulting in a remainder of 434.
Use 6 as the next digit of our solution. 
Result so far: 12091.6
Subtracting 5886 from 6320 leaves us with 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Moving on to step 10:
981 goes into 4340 4 times with a remainder of 416.
The number 4 becomes the next digit in our result. 
Result so far: 12091.64
If we take 3924 away from 4340, we end up with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Let's proceed to step 11:
The number 981 fits into 4160 4 times, leaving a remainder of 236.
The number 4 becomes the next digit in our result. 
Result so far: 12091.644
Subtract 3924 from 4160 to get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Our division results in 12091.644 with a remaining 0.0236.
