38647490 ÷ 964 
Our goal is to divide 38647490 by 964.

Moving on to step 1:
If we divide 3 by 964, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 964

On to step 2:
38 divided by 964 is 0 with a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Fetch the next digit (6) from the dividend, attach it to 38 and continue: 386 / 964

Moving on to step 3:
964 can be fit into 386 0 times, resulting in a remainder of 386.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 386 after subtracting 0 from 386.
Take the next digit (4) from the dividend and append it to 386, then repeat: 3864 / 964

Advancing to step 4:
964 can be fit into 3864 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 3856 from 3864 and we're left with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 964

On to step 5:
The number 964 fits into 87 0 times, leaving a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
Subtract 0 from 87 to get 87.
Take the next digit (4) from the dividend and append it to 87, then repeat: 874 / 964

Let's proceed to step 6:
874 divided by 964 is 0 with a remainder of 874.
The number 0 becomes the next digit in our result. 
Result so far: 400.0
If we subtract 0 from 874, we get 874.
Grab the next digit (9) from the dividend, add it to 874, then carry on: 8749 / 964

Let's proceed to step 7:
964 goes into 8749 9 times with a remainder of 73.
Use 9 as the next digit of our solution. 
Result so far: 4009.0
Subtracting 8676 from 8749 leaves us with 73.
Grab the next digit (0) from the dividend, add it to 73, then carry on: 730 / 964

Let's proceed to step 8:
964 can be fit into 730 0 times, resulting in a remainder of 730.
The next digit of our result is 0. 
Result so far: 40090.0
If we take 0 away from 730, we end up with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Moving on to step 9:
964 can be fit into 7300 7 times, resulting in a remainder of 552.
Put 7 as the next digit of the answer. 
Result so far: 40090.7
If we take 6748 away from 7300, we end up with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Going ahead to step 10:
When dividing 5520 by 964, we get 5 with a remainder of 700.
Record the quotient 5 as the next digit in the result. 
Result so far: 40090.75
If we subtract 4820 from 5520, we get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Moving on to step 11:
If we divide 7000 by 964, we get 7 and a remainder of 252.
Put 7 as the next digit of the answer. 
Result so far: 40090.757
Subtracting 6748 from 7000 leaves us with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

On to step 12:
964 goes into 2520 2 times with a remainder of 592.
Write down 2 as next digit of the result. 
Result so far: 40090.7572
Subtract 1928 from 2520 to get 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Going ahead to step 13:
The number 964 fits into 5920 6 times, leaving a remainder of 136.
The number 6 becomes the next digit in our result. 
Result so far: 40090.75726
Deduct 5784 from 5920 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Advancing to step 14:
When dividing 1360 by 964, we get 1 with a remainder of 396.
Use 1 as the next digit of our solution. 
Result so far: 40090.757261
If we subtract 964 from 1360, we get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Step 15:
When dividing 3960 by 964, we get 4 with a remainder of 104.
Put 4 as the next digit of the answer. 
Result so far: 40090.7572614
If we subtract 3856 from 3960, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 16:
1040 divided by 964 is 1 with a remainder of 76.
Use 1 as the next digit of our solution. 
Result so far: 40090.75726141
Deduct 964 from 1040 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

After the division, we end up with 40090.75726141 and a remainder of 7.6e-08.
