We're dividing 77643545 by 972 
Let's see how many times 972 fits into 77643545.

Let's proceed to step 1:
972 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 972

Going ahead to step 2:
77 divided by 972 is 0 with a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Append the next digit (6) from the dividend to 77 and continue with: 776 / 972

Let's proceed to step 3:
972 can be fit into 776 0 times, resulting in a remainder of 776.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 776 leaves us with 776.
Append the next digit (4) from the dividend to 776 and continue with: 7764 / 972

On to step 4:
7764 divided by 972 is 7 with a remainder of 960.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 6804 from 7764 to get 960.
Include the next digit (3) from the dividend after 960, then repeat: 9603 / 972

Moving on to step 5:
When dividing 9603 by 972, we get 9 with a remainder of 855.
Use 9 as the next digit of our solution. 
Result so far: 79.0
Subtracting 8748 from 9603 leaves us with 855.
Fetch the next digit (5) from the dividend, attach it to 855 and continue: 8555 / 972

Let's proceed to step 6:
972 goes into 8555 8 times with a remainder of 779.
Record the quotient 8 as the next digit in the result. 
Result so far: 798.0
If we subtract 7776 from 8555, we get 779.
Include the next digit (4) from the dividend after 779, then repeat: 7794 / 972

Step 7:
972 can be fit into 7794 8 times, resulting in a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 7988.0
If we take 7776 away from 7794, we end up with 18.
Grab the next digit (5) from the dividend, add it to 18, then carry on: 185 / 972

Going ahead to step 8:
972 goes into 185 0 times with a remainder of 185.
Put 0 as the next digit of the answer. 
Result so far: 79880.0
Deduct 0 from 185 and we're left with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Moving on to step 9:
If we divide 1850 by 972, we get 1 and a remainder of 878.
The number 1 becomes the next digit in our result. 
Result so far: 79880.1
If we subtract 972 from 1850, we get 878.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8780, and continue the process.

Moving on to step 10:
When dividing 8780 by 972, we get 9 with a remainder of 32.
Use 9 as the next digit of our solution. 
Result so far: 79880.19
The remainder is 32 after subtracting 8748 from 8780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 11:
972 can be fit into 320 0 times, resulting in a remainder of 320.
Use 0 as the next digit of our solution. 
Result so far: 79880.19
If we subtract 0 from 320, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 12:
3200 divided by 972 is 3 with a remainder of 284.
The number 3 becomes the next digit in our result. 
Result so far: 79880.1903
If we take 2916 away from 3200, we end up with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

On to step 13:
If we divide 2840 by 972, we get 2 and a remainder of 896.
The number 2 becomes the next digit in our result. 
Result so far: 79880.19032
Subtract 1944 from 2840 to get 896.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8960, and continue the process.

Let's proceed to step 14:
972 goes into 8960 9 times with a remainder of 212.
Write down 9 as next digit of the result. 
Result so far: 79880.190329
The remainder is 212 after subtracting 8748 from 8960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Moving on to step 15:
When dividing 2120 by 972, we get 2 with a remainder of 176.
The next digit of our result is 2. 
Result so far: 79880.1903292
If we subtract 1944 from 2120, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Advancing to step 16:
If we divide 1760 by 972, we get 1 and a remainder of 788.
Use 1 as the next digit of our solution. 
Result so far: 79880.19032921
Subtracting 972 from 1760 leaves us with 788.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7880, and continue the process.

The quotient of the division is 79880.19032921, and the remainder is 7.88e-07.
