13816408 ÷ 121 
Our goal is to divide 13816408 by 121.

Step 1:
121 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 121

On to step 2:
121 can be fit into 13 0 times, resulting in a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 121

Advancing to step 3:
The number 121 fits into 138 1 times, leaving a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 121 away from 138, we end up with 17.
Bring next digit (1) of the dividend behind the 17 and repeat the process: 171 / 121

Moving on to step 4:
The number 121 fits into 171 1 times, leaving a remainder of 50.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we take 121 away from 171, we end up with 50.
Append the next digit (6) from the dividend to 50 and continue with: 506 / 121

Going ahead to step 5:
121 can be fit into 506 4 times, resulting in a remainder of 22.
The next digit of our result is 4. 
Result so far: 114.0
If we subtract 484 from 506, we get 22.
Bring next digit (4) of the dividend behind the 22 and repeat the process: 224 / 121

On to step 6:
If we divide 224 by 121, we get 1 and a remainder of 103.
Put 1 as the next digit of the answer. 
Result so far: 1141.0
Subtract 121 from 224 to get 103.
Include the next digit (0) from the dividend after 103, then repeat: 1030 / 121

Going ahead to step 7:
121 goes into 1030 8 times with a remainder of 62.
Put 8 as the next digit of the answer. 
Result so far: 11418.0
Subtract 968 from 1030 to get 62.
Grab the next digit (8) from the dividend, add it to 62, then carry on: 628 / 121

Let's proceed to step 8:
628 divided by 121 is 5 with a remainder of 23.
Use 5 as the next digit of our solution. 
Result so far: 114185.0
The remainder is 23 after subtracting 605 from 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 9:
121 goes into 230 1 times with a remainder of 109.
Record the quotient 1 as the next digit in the result. 
Result so far: 114185.1
Subtract 121 from 230 to get 109.
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 10:
1090 divided by 121 is 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 114185.19
If we take 1089 away from 1090, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 11:
The number 121 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 114185.19
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
When dividing 100 by 121, we get 0 with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 114185.19
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Our division results in 114185.19 with a remaining 0.001.
