We divide 66599765 by 121
We're looking to find how many times 121 goes into 66599765.

Going ahead to step 1:
If we divide 6 by 121, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 121

Advancing to step 2:
121 goes into 66 0 times with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Append the next digit (5) from the dividend to 66 and continue with: 665 / 121

Advancing to step 3:
121 goes into 665 5 times with a remainder of 60.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 605 from 665 and we're left with 60.
Grab the next digit (9) from the dividend, add it to 60, then carry on: 609 / 121

Going ahead to step 4:
121 can be fit into 609 5 times, resulting in a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 55.0
Subtracting 605 from 609 leaves us with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 121

Advancing to step 5:
49 divided by 121 is 0 with a remainder of 49.
Use 0 as the next digit of our solution. 
Result so far: 550.0
Deduct 0 from 49 and we're left with 49.
Grab the next digit (7) from the dividend, add it to 49, then carry on: 497 / 121

Advancing to step 6:
121 can be fit into 497 4 times, resulting in a remainder of 13.
Record the quotient 4 as the next digit in the result. 
Result so far: 5504.0
Subtract 484 from 497 to get 13.
Include the next digit (6) from the dividend after 13, then repeat: 136 / 121

Moving on to step 7:
The number 121 fits into 136 1 times, leaving a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 55041.0
If we subtract 121 from 136, we get 15.
Take the next digit (5) from the dividend and append it to 15, then repeat: 155 / 121

Let's proceed to step 8:
If we divide 155 by 121, we get 1 and a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 550411.0
Subtract 121 from 155 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 9:
121 can be fit into 340 2 times, resulting in a remainder of 98.
The next digit of our result is 2. 
Result so far: 550411.2
If we take 242 away from 340, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Advancing to step 10:
The number 121 fits into 980 8 times, leaving a remainder of 12.
The next digit of our result is 8. 
Result so far: 550411.28
If we take 968 away from 980, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 11:
121 goes into 120 0 times with a remainder of 120.
The next digit of our result is 0. 
Result so far: 550411.28
Subtracting 0 from 120 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 12:
If we divide 1200 by 121, we get 9 and a remainder of 111.
Put 9 as the next digit of the answer. 
Result so far: 550411.2809
Subtract 1089 from 1200 to get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Moving on to step 13:
121 can be fit into 1110 9 times, resulting in a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 550411.28099
Deduct 1089 from 1110 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Our division results in 550411.28099 with a remaining 2.1e-05.
