Let's divide 21876563 by 121
We want to figure out the number of times 21876563 can be divided by 121.

Moving on to step 1:
The number 121 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 121

Let's proceed to step 2:
121 goes into 21 0 times with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Take the next digit (8) from the dividend and append it to 21, then repeat: 218 / 121

Advancing to step 3:
121 can be fit into 218 1 times, resulting in a remainder of 97.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 121 from 218 to get 97.
Bring next digit (7) of the dividend behind the 97 and repeat the process: 977 / 121

Moving on to step 4:
The number 121 fits into 977 8 times, leaving a remainder of 9.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
The remainder is 9 after subtracting 968 from 977.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 121

Moving on to step 5:
121 goes into 96 0 times with a remainder of 96.
Use 0 as the next digit of our solution. 
Result so far: 180.0
Deduct 0 from 96 and we're left with 96.
Grab the next digit (5) from the dividend, add it to 96, then carry on: 965 / 121

Step 6:
The number 121 fits into 965 7 times, leaving a remainder of 118.
The number 7 becomes the next digit in our result. 
Result so far: 1807.0
Deduct 847 from 965 and we're left with 118.
Bring next digit (6) of the dividend behind the 118 and repeat the process: 1186 / 121

On to step 7:
121 can be fit into 1186 9 times, resulting in a remainder of 97.
Record the quotient 9 as the next digit in the result. 
Result so far: 18079.0
The remainder is 97 after subtracting 1089 from 1186.
Bring next digit (3) of the dividend behind the 97 and repeat the process: 973 / 121

On to step 8:
121 goes into 973 8 times with a remainder of 5.
Write down 8 as next digit of the result. 
Result so far: 180798.0
The remainder is 5 after subtracting 968 from 973.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
If we divide 50 by 121, we get 0 and a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 180798.0
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 10:
121 goes into 500 4 times with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 180798.04
Subtracting 484 from 500 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
When dividing 160 by 121, we get 1 with a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 180798.041
Subtract 121 from 160 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 12:
121 goes into 390 3 times with a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 180798.0413
The remainder is 27 after subtracting 363 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 13:
270 divided by 121 is 2 with a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 180798.04132
Subtracting 242 from 270 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 14:
121 can be fit into 280 2 times, resulting in a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 180798.041322
Subtracting 242 from 280 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final outcome is 180798.041322, with a leftover of 3.8e-06.
