We look at the division of 67452419 by 121 
Our goal is to divide 67452419 by 121.

On to step 1:
6 divided by 121 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 121

Going ahead to step 2:
121 goes into 67 0 times with a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 67 after subtracting 0 from 67.
Take the next digit (4) from the dividend and append it to 67, then repeat: 674 / 121

Let's proceed to step 3:
121 can be fit into 674 5 times, resulting in a remainder of 69.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 605 away from 674, we end up with 69.
Fetch the next digit (5) from the dividend, attach it to 69 and continue: 695 / 121

Step 4:
The number 121 fits into 695 5 times, leaving a remainder of 90.
Write down 5 as next digit of the result. 
Result so far: 55.0
Subtract 605 from 695 to get 90.
Include the next digit (2) from the dividend after 90, then repeat: 902 / 121

Going ahead to step 5:
121 can be fit into 902 7 times, resulting in a remainder of 55.
Use 7 as the next digit of our solution. 
Result so far: 557.0
If we subtract 847 from 902, we get 55.
Append the next digit (4) from the dividend to 55 and continue with: 554 / 121

Going ahead to step 6:
121 can be fit into 554 4 times, resulting in a remainder of 70.
Use 4 as the next digit of our solution. 
Result so far: 5574.0
Deduct 484 from 554 and we're left with 70.
Bring next digit (1) of the dividend behind the 70 and repeat the process: 701 / 121

Step 7:
121 can be fit into 701 5 times, resulting in a remainder of 96.
Record the quotient 5 as the next digit in the result. 
Result so far: 55745.0
If we take 605 away from 701, we end up with 96.
Append the next digit (9) from the dividend to 96 and continue with: 969 / 121

On to step 8:
If we divide 969 by 121, we get 8 and a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 557458.0
Subtract 968 from 969 to get 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 9:
10 divided by 121 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 557458.0
If we subtract 0 from 10, we 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.

Advancing to step 10:
100 divided by 121 is 0 with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 557458.0
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.

The final outcome is 557458.0, with a leftover of 0.1.
