We look at the division of 7403579 by 121 
We want to figure out the number of times 7403579 can be divided by 121.

On to step 1:
The number 121 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 121

Going ahead to step 2:
When dividing 74 by 121, we get 0 with a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 74 leaves us with 74.
Fetch the next digit (0) from the dividend, attach it to 74 and continue: 740 / 121

Let's proceed to step 3:
740 divided by 121 is 6 with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 14 after subtracting 726 from 740.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 121

Going ahead to step 4:
143 divided by 121 is 1 with a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 61.0
If we take 121 away from 143, we end up with 22.
Append the next digit (5) from the dividend to 22 and continue with: 225 / 121

Step 5:
121 can be fit into 225 1 times, resulting in a remainder of 104.
The number 1 becomes the next digit in our result. 
Result so far: 611.0
If we subtract 121 from 225, we get 104.
Fetch the next digit (7) from the dividend, attach it to 104 and continue: 1047 / 121

Step 6:
121 can be fit into 1047 8 times, resulting in a remainder of 79.
Record the quotient 8 as the next digit in the result. 
Result so far: 6118.0
If we subtract 968 from 1047, we get 79.
Fetch the next digit (9) from the dividend, attach it to 79 and continue: 799 / 121

Going ahead to step 7:
When dividing 799 by 121, we get 6 with a remainder of 73.
The number 6 becomes the next digit in our result. 
Result so far: 61186.0
If we take 726 away from 799, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 8:
730 divided by 121 is 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 61186.6
The remainder is 4 after subtracting 726 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
If we divide 40 by 121, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 61186.6
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
The number 121 fits into 400 3 times, leaving a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 61186.603
The remainder is 37 after subtracting 363 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 11:
370 divided by 121 is 3 with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 61186.6033
Subtract 363 from 370 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The quotient of the division is 61186.6033, and the remainder is 7e-05.
