Let's divide 83664443 by 964
We're looking to find how many times 964 goes into 83664443.

Going ahead to step 1:
964 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 964

Moving on to step 2:
964 goes into 83 0 times with a remainder of 83.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 83 to get 83.
Include the next digit (6) from the dividend after 83, then repeat: 836 / 964

Moving on to step 3:
When dividing 836 by 964, we get 0 with a remainder of 836.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 836 after subtracting 0 from 836.
Fetch the next digit (6) from the dividend, attach it to 836 and continue: 8366 / 964

Going ahead to step 4:
If we divide 8366 by 964, we get 8 and a remainder of 654.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 7712 from 8366, we get 654.
Include the next digit (4) from the dividend after 654, then repeat: 6544 / 964

Advancing to step 5:
964 can be fit into 6544 6 times, resulting in a remainder of 760.
Use 6 as the next digit of our solution. 
Result so far: 86.0
Subtracting 5784 from 6544 leaves us with 760.
Take the next digit (4) from the dividend and append it to 760, then repeat: 7604 / 964

Going ahead to step 6:
964 can be fit into 7604 7 times, resulting in a remainder of 856.
The number 7 becomes the next digit in our result. 
Result so far: 867.0
Subtracting 6748 from 7604 leaves us with 856.
Grab the next digit (4) from the dividend, add it to 856, then carry on: 8564 / 964

On to step 7:
If we divide 8564 by 964, we get 8 and a remainder of 852.
Record the quotient 8 as the next digit in the result. 
Result so far: 8678.0
The remainder is 852 after subtracting 7712 from 8564.
Fetch the next digit (3) from the dividend, attach it to 852 and continue: 8523 / 964

Advancing to step 8:
964 goes into 8523 8 times with a remainder of 811.
Record the quotient 8 as the next digit in the result. 
Result so far: 86788.0
Subtracting 7712 from 8523 leaves us with 811.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8110, and continue the process.

On to step 9:
The number 964 fits into 8110 8 times, leaving a remainder of 398.
Put 8 as the next digit of the answer. 
Result so far: 86788.8
Subtracting 7712 from 8110 leaves us with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Advancing to step 10:
3980 divided by 964 is 4 with a remainder of 124.
Put 4 as the next digit of the answer. 
Result so far: 86788.84
Deduct 3856 from 3980 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 11:
964 goes into 1240 1 times with a remainder of 276.
The number 1 becomes the next digit in our result. 
Result so far: 86788.841
The remainder is 276 after subtracting 964 from 1240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Moving on to step 12:
The number 964 fits into 2760 2 times, leaving a remainder of 832.
The next digit of our result is 2. 
Result so far: 86788.8412
If we subtract 1928 from 2760, we get 832.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8320, and continue the process.

Let's proceed to step 13:
8320 divided by 964 is 8 with a remainder of 608.
Use 8 as the next digit of our solution. 
Result so far: 86788.84128
The remainder is 608 after subtracting 7712 from 8320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Step 14:
964 can be fit into 6080 6 times, resulting in a remainder of 296.
Use 6 as the next digit of our solution. 
Result so far: 86788.841286
If we subtract 5784 from 6080, we get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

On to step 15:
If we divide 2960 by 964, we get 3 and a remainder of 68.
The next digit of our result is 3. 
Result so far: 86788.8412863
Deduct 2892 from 2960 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 16:
964 can be fit into 680 0 times, resulting in a remainder of 680.
The next digit of our result is 0. 
Result so far: 86788.8412863
The remainder is 680 after subtracting 0 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

The quotient of the division is 86788.8412863, and the remainder is 6.8e-07.
