We're dividing 75431605 by 66 
We want to figure out the number of times 75431605 can be divided by 66.

Let's proceed to step 1:
66 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 66

Advancing to step 2:
When dividing 75 by 66, we get 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 66 from 75 to get 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 66

Step 3:
When dividing 94 by 66, we get 1 with a remainder of 28.
The next digit of our result is 1. 
Result so far: 11.0
Deduct 66 from 94 and we're left with 28.
Include the next digit (3) from the dividend after 28, then repeat: 283 / 66

On to step 4:
If we divide 283 by 66, we get 4 and a remainder of 19.
Write down 4 as next digit of the result. 
Result so far: 114.0
If we take 264 away from 283, we end up with 19.
Fetch the next digit (1) from the dividend, attach it to 19 and continue: 191 / 66

Advancing to step 5:
66 can be fit into 191 2 times, resulting in a remainder of 59.
Record the quotient 2 as the next digit in the result. 
Result so far: 1142.0
Deduct 132 from 191 and we're left with 59.
Fetch the next digit (6) from the dividend, attach it to 59 and continue: 596 / 66

Let's proceed to step 6:
When dividing 596 by 66, we get 9 with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 11429.0
Deduct 594 from 596 and we're left with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 66

Moving on to step 7:
If we divide 20 by 66, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 114290.0
Subtracting 0 from 20 leaves us with 20.
Include the next digit (5) from the dividend after 20, then repeat: 205 / 66

On to step 8:
When dividing 205 by 66, we get 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 1142903.0
The remainder is 7 after subtracting 198 from 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 9:
66 goes into 70 1 times with a remainder of 4.
The next digit of our result is 1. 
Result so far: 1142903.1
Deduct 66 from 70 and we're left with 4.
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 10:
66 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 1142903.1
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.

Moving on to step 11:
400 divided by 66 is 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 1142903.106
If we take 396 away from 400, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 12:
When dividing 40 by 66, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 1142903.106
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 13:
66 can be fit into 400 6 times, resulting in a remainder of 4.
The next digit of our result is 6. 
Result so far: 1142903.10606
Subtracting 396 from 400 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 14:
66 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 1142903.10606
If we subtract 0 from 40, we get 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 15:
66 goes into 400 6 times with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 1142903.1060606
Subtract 396 from 400 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 16:
66 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 1142903.1060606
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 1142903.1060606 with a balance of 4e-08.
