87898900 ÷ 964 
We want to figure out the number of times 87898900 can be divided by 964.

Let's proceed to step 1:
964 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 964

Advancing to step 2:
964 goes into 87 0 times with a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Fetch the next digit (8) from the dividend, attach it to 87 and continue: 878 / 964

On to step 3:
If we divide 878 by 964, we get 0 and a remainder of 878.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 878, we get 878.
Fetch the next digit (9) from the dividend, attach it to 878 and continue: 8789 / 964

Moving on to step 4:
8789 divided by 964 is 9 with a remainder of 113.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 8676 away from 8789, we end up with 113.
Take the next digit (8) from the dividend and append it to 113, then repeat: 1138 / 964

Step 5:
964 goes into 1138 1 times with a remainder of 174.
Write down 1 as next digit of the result. 
Result so far: 91.0
Subtract 964 from 1138 to get 174.
Fetch the next digit (9) from the dividend, attach it to 174 and continue: 1749 / 964

Moving on to step 6:
The number 964 fits into 1749 1 times, leaving a remainder of 785.
Use 1 as the next digit of our solution. 
Result so far: 911.0
The remainder is 785 after subtracting 964 from 1749.
Include the next digit (0) from the dividend after 785, then repeat: 7850 / 964

Step 7:
964 can be fit into 7850 8 times, resulting in a remainder of 138.
Use 8 as the next digit of our solution. 
Result so far: 9118.0
Subtract 7712 from 7850 to get 138.
Include the next digit (0) from the dividend after 138, then repeat: 1380 / 964

Advancing to step 8:
964 goes into 1380 1 times with a remainder of 416.
Record the quotient 1 as the next digit in the result. 
Result so far: 91181.0
Subtract 964 from 1380 to get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Going ahead to step 9:
964 can be fit into 4160 4 times, resulting in a remainder of 304.
Record the quotient 4 as the next digit in the result. 
Result so far: 91181.4
Deduct 3856 from 4160 and we're left with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

On to step 10:
The number 964 fits into 3040 3 times, leaving a remainder of 148.
Use 3 as the next digit of our solution. 
Result so far: 91181.43
Deduct 2892 from 3040 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 11:
964 can be fit into 1480 1 times, resulting in a remainder of 516.
The next digit of our result is 1. 
Result so far: 91181.431
If we take 964 away from 1480, we end up with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Step 12:
964 can be fit into 5160 5 times, resulting in a remainder of 340.
Record the quotient 5 as the next digit in the result. 
Result so far: 91181.4315
Subtract 4820 from 5160 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 13:
The number 964 fits into 3400 3 times, leaving a remainder of 508.
The number 3 becomes the next digit in our result. 
Result so far: 91181.43153
Deduct 2892 from 3400 and we're left with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Going ahead to step 14:
5080 divided by 964 is 5 with a remainder of 260.
Use 5 as the next digit of our solution. 
Result so far: 91181.431535
Deduct 4820 from 5080 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 15:
964 goes into 2600 2 times with a remainder of 672.
Use 2 as the next digit of our solution. 
Result so far: 91181.4315352
If we subtract 1928 from 2600, we get 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Moving on to step 16:
If we divide 6720 by 964, we get 6 and a remainder of 936.
The next digit of our result is 6. 
Result so far: 91181.43153526
Subtract 5784 from 6720 to get 936.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9360, and continue the process.

Our division results in 91181.43153526 with a remaining 9.36e-07.
