We look at the division of 83544080 by 964 
We want to figure out the number of times 83544080 can be divided by 964.

On to step 1:
The number 964 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 964

On to step 2:
The number 964 fits into 83 0 times, leaving a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 83, we end up with 83.
Fetch the next digit (5) from the dividend, attach it to 83 and continue: 835 / 964

Advancing to step 3:
If we divide 835 by 964, we get 0 and a remainder of 835.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 835 leaves us with 835.
Include the next digit (4) from the dividend after 835, then repeat: 8354 / 964

Let's proceed to step 4:
The number 964 fits into 8354 8 times, leaving a remainder of 642.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 642 after subtracting 7712 from 8354.
Take the next digit (4) from the dividend and append it to 642, then repeat: 6424 / 964

On to step 5:
When dividing 6424 by 964, we get 6 with a remainder of 640.
Use 6 as the next digit of our solution. 
Result so far: 86.0
Subtracting 5784 from 6424 leaves us with 640.
Append the next digit (0) from the dividend to 640 and continue with: 6400 / 964

Let's proceed to step 6:
964 can be fit into 6400 6 times, resulting in a remainder of 616.
The number 6 becomes the next digit in our result. 
Result so far: 866.0
If we subtract 5784 from 6400, we get 616.
Grab the next digit (8) from the dividend, add it to 616, then carry on: 6168 / 964

Advancing to step 7:
When dividing 6168 by 964, we get 6 with a remainder of 384.
The number 6 becomes the next digit in our result. 
Result so far: 8666.0
Subtracting 5784 from 6168 leaves us with 384.
Take the next digit (0) from the dividend and append it to 384, then repeat: 3840 / 964

Going ahead to step 8:
When dividing 3840 by 964, we get 3 with a remainder of 948.
The number 3 becomes the next digit in our result. 
Result so far: 86663.0
Subtracting 2892 from 3840 leaves us with 948.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9480, and continue the process.

Going ahead to step 9:
964 can be fit into 9480 9 times, resulting in a remainder of 804.
The number 9 becomes the next digit in our result. 
Result so far: 86663.9
If we subtract 8676 from 9480, we get 804.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8040, and continue the process.

Step 10:
When dividing 8040 by 964, we get 8 with a remainder of 328.
Record the quotient 8 as the next digit in the result. 
Result so far: 86663.98
Subtracting 7712 from 8040 leaves us 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 11:
3280 divided by 964 is 3 with a remainder of 388.
Record the quotient 3 as the next digit in the result. 
Result so far: 86663.983
If we subtract 2892 from 3280, we 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.

Step 12:
964 can be fit into 3880 4 times, resulting in a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 86663.9834
The remainder is 24 after subtracting 3856 from 3880.
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 13:
964 goes into 240 0 times with a remainder of 240.
Put 0 as the next digit of the answer. 
Result so far: 86663.9834
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.

Let's proceed to step 14:
The number 964 fits into 2400 2 times, leaving a remainder of 472.
Put 2 as the next digit of the answer. 
Result so far: 86663.983402
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.

Moving on to step 15:
4720 divided by 964 is 4 with a remainder of 864.
The number 4 becomes the next digit in our result. 
Result so far: 86663.9834024
Subtracting 3856 from 4720 leaves us 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.

On to step 16:
If we divide 8640 by 964, we get 8 and a remainder of 928.
Put 8 as the next digit of the answer. 
Result so far: 86663.98340248
Deduct 7712 from 8640 and we're left with 928.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9280, and continue the process.

The final result is 86663.98340248 with a remainder of 9.28e-07.
