We look at the division of 75140373 by 121 
We're looking to find how many times 121 goes into 75140373.

Going ahead to step 1:
The number 121 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 121

Moving on to step 2:
When dividing 75 by 121, we get 0 with a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Append the next digit (1) from the dividend to 75 and continue with: 751 / 121

Step 3:
751 divided by 121 is 6 with a remainder of 25.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 726 from 751 and we're left with 25.
Append the next digit (4) from the dividend to 25 and continue with: 254 / 121

Going ahead to step 4:
254 divided by 121 is 2 with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 62.0
Subtracting 242 from 254 leaves us with 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 121

Step 5:
121 goes into 120 0 times with a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 620.0
Deduct 0 from 120 and we're left with 120.
Grab the next digit (3) from the dividend, add it to 120, then carry on: 1203 / 121

Let's proceed to step 6:
If we divide 1203 by 121, we get 9 and a remainder of 114.
Record the quotient 9 as the next digit in the result. 
Result so far: 6209.0
If we take 1089 away from 1203, we end up with 114.
Include the next digit (7) from the dividend after 114, then repeat: 1147 / 121

Moving on to step 7:
121 goes into 1147 9 times with a remainder of 58.
The number 9 becomes the next digit in our result. 
Result so far: 62099.0
If we subtract 1089 from 1147, we get 58.
Include the next digit (3) from the dividend after 58, then repeat: 583 / 121

Moving on to step 8:
When dividing 583 by 121, we get 4 with a remainder of 99.
The next digit of our result is 4. 
Result so far: 620994.0
If we take 484 away from 583, we end up with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Going ahead to step 9:
121 goes into 990 8 times with a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 620994.8
The remainder is 22 after subtracting 968 from 990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 10:
121 can be fit into 220 1 times, resulting in a remainder of 99.
Write down 1 as next digit of the result. 
Result so far: 620994.81
If we subtract 121 from 220, we get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Moving on to step 11:
When dividing 990 by 121, we get 8 with a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 620994.818
The remainder is 22 after subtracting 968 from 990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 12:
If we divide 220 by 121, we get 1 and a remainder of 99.
Use 1 as the next digit of our solution. 
Result so far: 620994.8181
Deduct 121 from 220 and we're left with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Going ahead to step 13:
The number 121 fits into 990 8 times, leaving a remainder of 22.
The next digit of our result is 8. 
Result so far: 620994.81818
If we take 968 away from 990, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 14:
The number 121 fits into 220 1 times, leaving a remainder of 99.
Put 1 as the next digit of the answer. 
Result so far: 620994.818181
Subtracting 121 from 220 leaves us with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Step 15:
121 can be fit into 990 8 times, resulting in a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 620994.8181818
Subtract 968 from 990 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 16:
121 goes into 220 1 times with a remainder of 99.
Record the quotient 1 as the next digit in the result. 
Result so far: 620994.81818181
Subtracting 121 from 220 leaves us with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

After the division, we end up with 620994.81818181 and a remainder of 9.9e-08.
