We look at the division of 73866161 by 972 
We're looking to find how many times 972 goes into 73866161.

Going ahead to step 1:
7 divided by 972 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 972

Let's proceed to step 2:
972 goes into 73 0 times with a remainder of 73.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Grab the next digit (8) from the dividend, add it to 73, then carry on: 738 / 972

Advancing to step 3:
When dividing 738 by 972, we get 0 with a remainder of 738.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 738 after subtracting 0 from 738.
Bring next digit (6) of the dividend behind the 738 and repeat the process: 7386 / 972

Going ahead to step 4:
7386 divided by 972 is 7 with a remainder of 582.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 582 after subtracting 6804 from 7386.
Include the next digit (6) from the dividend after 582, then repeat: 5826 / 972

On to step 5:
5826 divided by 972 is 5 with a remainder of 966.
The number 5 becomes the next digit in our result. 
Result so far: 75.0
If we subtract 4860 from 5826, we get 966.
Bring next digit (1) of the dividend behind the 966 and repeat the process: 9661 / 972

Let's proceed to step 6:
972 goes into 9661 9 times with a remainder of 913.
Put 9 as the next digit of the answer. 
Result so far: 759.0
The remainder is 913 after subtracting 8748 from 9661.
Bring next digit (6) of the dividend behind the 913 and repeat the process: 9136 / 972

On to step 7:
When dividing 9136 by 972, we get 9 with a remainder of 388.
Put 9 as the next digit of the answer. 
Result so far: 7599.0
Deduct 8748 from 9136 and we're left with 388.
Append the next digit (1) from the dividend to 388 and continue with: 3881 / 972

Going ahead to step 8:
The number 972 fits into 3881 3 times, leaving a remainder of 965.
Put 3 as the next digit of the answer. 
Result so far: 75993.0
If we subtract 2916 from 3881, we get 965.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9650, and continue the process.

Moving on to step 9:
When dividing 9650 by 972, we get 9 with a remainder of 902.
The number 9 becomes the next digit in our result. 
Result so far: 75993.9
Subtracting 8748 from 9650 leaves us with 902.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9020, and continue the process.

On to step 10:
If we divide 9020 by 972, we get 9 and a remainder of 272.
Put 9 as the next digit of the answer. 
Result so far: 75993.99
Deduct 8748 from 9020 and we're left with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

The quotient of the division is 75993.99, and the remainder is 0.272.
