23561990 ÷ 964 
We're looking to find how many times 964 goes into 23561990.

Going ahead to step 1:
The number 964 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 964

Advancing to step 2:
23 divided by 964 is 0 with a remainder of 23.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Append the next digit (5) from the dividend to 23 and continue with: 235 / 964

Let's proceed to step 3:
If we divide 235 by 964, we get 0 and a remainder of 235.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 235 leaves us with 235.
Grab the next digit (6) from the dividend, add it to 235, then carry on: 2356 / 964

Advancing to step 4:
The number 964 fits into 2356 2 times, leaving a remainder of 428.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 1928 from 2356 to get 428.
Grab the next digit (1) from the dividend, add it to 428, then carry on: 4281 / 964

Step 5:
4281 divided by 964 is 4 with a remainder of 425.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
If we subtract 3856 from 4281, we get 425.
Fetch the next digit (9) from the dividend, attach it to 425 and continue: 4259 / 964

Advancing to step 6:
If we divide 4259 by 964, we get 4 and a remainder of 403.
Use 4 as the next digit of our solution. 
Result so far: 244.0
Subtracting 3856 from 4259 leaves us with 403.
Fetch the next digit (9) from the dividend, attach it to 403 and continue: 4039 / 964

Moving on to step 7:
964 can be fit into 4039 4 times, resulting in a remainder of 183.
The number 4 becomes the next digit in our result. 
Result so far: 2444.0
The remainder is 183 after subtracting 3856 from 4039.
Bring next digit (0) of the dividend behind the 183 and repeat the process: 1830 / 964

Moving on to step 8:
964 can be fit into 1830 1 times, resulting in a remainder of 866.
Put 1 as the next digit of the answer. 
Result so far: 24441.0
Deduct 964 from 1830 and we're left with 866.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8660, and continue the process.

Step 9:
The number 964 fits into 8660 8 times, leaving a remainder of 948.
The next digit of our result is 8. 
Result so far: 24441.8
Subtract 7712 from 8660 to get 948.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9480, and continue the process.

Moving on to step 10:
9480 divided by 964 is 9 with a remainder of 804.
Put 9 as the next digit of the answer. 
Result so far: 24441.89
The remainder is 804 after subtracting 8676 from 9480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8040, and continue the process.

Step 11:
The number 964 fits into 8040 8 times, leaving a remainder of 328.
The number 8 becomes the next digit in our result. 
Result so far: 24441.898
Deduct 7712 from 8040 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Going ahead to step 12:
If we divide 3280 by 964, we get 3 and a remainder of 388.
Record the quotient 3 as the next digit in the result. 
Result so far: 24441.8983
Subtract 2892 from 3280 to get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Moving on to step 13:
964 can be fit into 3880 4 times, resulting in a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 24441.89834
If we subtract 3856 from 3880, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 14:
964 can be fit into 240 0 times, resulting in a remainder of 240.
Write down 0 as next digit of the result. 
Result so far: 24441.89834
Deduct 0 from 240 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 15:
2400 divided by 964 is 2 with a remainder of 472.
Put 2 as the next digit of the answer. 
Result so far: 24441.8983402
If we subtract 1928 from 2400, we get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Step 16:
964 goes into 4720 4 times with a remainder of 864.
Put 4 as the next digit of the answer. 
Result so far: 24441.89834024
If we take 3856 away from 4720, we end up with 864.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8640, and continue the process.

Our division results in 24441.89834024 with a remaining 8.64e-07.
