We're dividing 38415135 by 972 
Let's see how many times 972 fits into 38415135.

Advancing to step 1:
972 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 972

On to step 2:
972 can be fit into 38 0 times, resulting in a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Bring next digit (4) of the dividend behind the 38 and repeat the process: 384 / 972

On to step 3:
972 goes into 384 0 times with a remainder of 384.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 384, we end up with 384.
Fetch the next digit (1) from the dividend, attach it to 384 and continue: 3841 / 972

Going ahead to step 4:
972 goes into 3841 3 times with a remainder of 925.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 2916 from 3841 to get 925.
Fetch the next digit (5) from the dividend, attach it to 925 and continue: 9255 / 972

Let's proceed to step 5:
972 can be fit into 9255 9 times, resulting in a remainder of 507.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
If we subtract 8748 from 9255, we get 507.
Fetch the next digit (1) from the dividend, attach it to 507 and continue: 5071 / 972

Moving on to step 6:
5071 divided by 972 is 5 with a remainder of 211.
Record the quotient 5 as the next digit in the result. 
Result so far: 395.0
The remainder is 211 after subtracting 4860 from 5071.
Append the next digit (3) from the dividend to 211 and continue with: 2113 / 972

On to step 7:
When dividing 2113 by 972, we get 2 with a remainder of 169.
Write down 2 as next digit of the result. 
Result so far: 3952.0
Subtracting 1944 from 2113 leaves us with 169.
Grab the next digit (5) from the dividend, add it to 169, then carry on: 1695 / 972

On to step 8:
1695 divided by 972 is 1 with a remainder of 723.
Put 1 as the next digit of the answer. 
Result so far: 39521.0
Subtracting 972 from 1695 leaves us with 723.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7230, and continue the process.

Advancing to step 9:
7230 divided by 972 is 7 with a remainder of 426.
Record the quotient 7 as the next digit in the result. 
Result so far: 39521.7
Deduct 6804 from 7230 and we're left with 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Going ahead to step 10:
4260 divided by 972 is 4 with a remainder of 372.
Record the quotient 4 as the next digit in the result. 
Result so far: 39521.74
If we subtract 3888 from 4260, we get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Let's proceed to step 11:
972 goes into 3720 3 times with a remainder of 804.
Use 3 as the next digit of our solution. 
Result so far: 39521.743
If we take 2916 away from 3720, we end up with 804.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8040, and continue the process.

Let's proceed to step 12:
If we divide 8040 by 972, we get 8 and a remainder of 264.
The number 8 becomes the next digit in our result. 
Result so far: 39521.7438
Subtracting 7776 from 8040 leaves us with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Let's proceed to step 13:
When dividing 2640 by 972, we get 2 with a remainder of 696.
The number 2 becomes the next digit in our result. 
Result so far: 39521.74382
Subtracting 1944 from 2640 leaves us with 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Advancing to step 14:
972 can be fit into 6960 7 times, resulting in a remainder of 156.
The next digit of our result is 7. 
Result so far: 39521.743827
The remainder is 156 after subtracting 6804 from 6960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Advancing to step 15:
972 goes into 1560 1 times with a remainder of 588.
Record the quotient 1 as the next digit in the result. 
Result so far: 39521.7438271
If we take 972 away from 1560, we end up with 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Moving on to step 16:
972 can be fit into 5880 6 times, resulting in a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 39521.74382716
The remainder is 48 after subtracting 5832 from 5880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final result is 39521.74382716 with a remainder of 4.8e-08.
