Let's divide 43992143 by 975
We want to figure out the number of times 43992143 can be divided by 975.

Advancing to step 1:
If we divide 4 by 975, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 975

Step 2:
The number 975 fits into 43 0 times, leaving a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Take the next digit (9) from the dividend and append it to 43, then repeat: 439 / 975

Moving on to step 3:
When dividing 439 by 975, we get 0 with a remainder of 439.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 439 after subtracting 0 from 439.
Grab the next digit (9) from the dividend, add it to 439, then carry on: 4399 / 975

Let's proceed to step 4:
The number 975 fits into 4399 4 times, leaving a remainder of 499.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 3900 from 4399 and we're left with 499.
Include the next digit (2) from the dividend after 499, then repeat: 4992 / 975

Moving on to step 5:
If we divide 4992 by 975, we get 5 and a remainder of 117.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
If we take 4875 away from 4992, we end up with 117.
Include the next digit (1) from the dividend after 117, then repeat: 1171 / 975

Step 6:
975 can be fit into 1171 1 times, resulting in a remainder of 196.
Write down 1 as next digit of the result. 
Result so far: 451.0
If we take 975 away from 1171, we end up with 196.
Take the next digit (4) from the dividend and append it to 196, then repeat: 1964 / 975

Let's proceed to step 7:
When dividing 1964 by 975, we get 2 with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 4512.0
Deduct 1950 from 1964 and we're left with 14.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 975

Moving on to step 8:
If we divide 143 by 975, we get 0 and a remainder of 143.
The number 0 becomes the next digit in our result. 
Result so far: 45120.0
Deduct 0 from 143 and we're left with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Advancing to step 9:
1430 divided by 975 is 1 with a remainder of 455.
The next digit of our result is 1. 
Result so far: 45120.1
The remainder is 455 after subtracting 975 from 1430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Moving on to step 10:
4550 divided by 975 is 4 with a remainder of 650.
Use 4 as the next digit of our solution. 
Result so far: 45120.14
Deduct 3900 from 4550 and we're left with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Going ahead to step 11:
6500 divided by 975 is 6 with a remainder of 650.
The number 6 becomes the next digit in our result. 
Result so far: 45120.146
The remainder is 650 after subtracting 5850 from 6500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Step 12:
6500 divided by 975 is 6 with a remainder of 650.
Record the quotient 6 as the next digit in the result. 
Result so far: 45120.1466
Deduct 5850 from 6500 and we're left with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

The final result is 45120.1466 with a remainder of 0.0065.
