9978424 ÷ 964 
Our goal is to divide 9978424 by 964.

Going ahead to step 1:
The number 964 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 964

Going ahead to step 2:
99 divided by 964 is 0 with a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 99, we end up with 99.
Fetch the next digit (7) from the dividend, attach it to 99 and continue: 997 / 964

Going ahead to step 3:
When dividing 997 by 964, we get 1 with a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 964 from 997, we get 33.
Include the next digit (8) from the dividend after 33, then repeat: 338 / 964

On to step 4:
If we divide 338 by 964, we get 0 and a remainder of 338.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 338 to get 338.
Fetch the next digit (4) from the dividend, attach it to 338 and continue: 3384 / 964

Let's proceed to step 5:
964 can be fit into 3384 3 times, resulting in a remainder of 492.
Record the quotient 3 as the next digit in the result. 
Result so far: 103.0
Subtract 2892 from 3384 to get 492.
Grab the next digit (2) from the dividend, add it to 492, then carry on: 4922 / 964

Let's proceed to step 6:
4922 divided by 964 is 5 with a remainder of 102.
Use 5 as the next digit of our solution. 
Result so far: 1035.0
If we subtract 4820 from 4922, we get 102.
Append the next digit (4) from the dividend to 102 and continue with: 1024 / 964

Going ahead to step 7:
If we divide 1024 by 964, we get 1 and a remainder of 60.
The number 1 becomes the next digit in our result. 
Result so far: 10351.0
The remainder is 60 after subtracting 964 from 1024.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 8:
When dividing 600 by 964, we get 0 with a remainder of 600.
Use 0 as the next digit of our solution. 
Result so far: 10351.0
Subtracting 0 from 600 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Let's proceed to step 9:
The number 964 fits into 6000 6 times, leaving a remainder of 216.
The number 6 becomes the next digit in our result. 
Result so far: 10351.06
Subtracting 5784 from 6000 leaves us with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Let's proceed to step 10:
2160 divided by 964 is 2 with a remainder of 232.
Record the quotient 2 as the next digit in the result. 
Result so far: 10351.062
The remainder is 232 after subtracting 1928 from 2160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Advancing to step 11:
964 can be fit into 2320 2 times, resulting in a remainder of 392.
The number 2 becomes the next digit in our result. 
Result so far: 10351.0622
Subtract 1928 from 2320 to get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

The final outcome is 10351.0622, with a leftover of 0.00392.
