We're dividing 39647216 by 945 
We want to figure out the number of times 39647216 can be divided by 945.

On to step 1:
The number 945 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 945

Step 2:
If we divide 39 by 945, we get 0 and a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Take the next digit (6) from the dividend and append it to 39, then repeat: 396 / 945

Going ahead to step 3:
When dividing 396 by 945, we get 0 with a remainder of 396.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 396 to get 396.
Bring next digit (4) of the dividend behind the 396 and repeat the process: 3964 / 945

Moving on to step 4:
3964 divided by 945 is 4 with a remainder of 184.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 3780 from 3964 leaves us with 184.
Bring next digit (7) of the dividend behind the 184 and repeat the process: 1847 / 945

Moving on to step 5:
945 goes into 1847 1 times with a remainder of 902.
The next digit of our result is 1. 
Result so far: 41.0
Subtracting 945 from 1847 leaves us with 902.
Bring next digit (2) of the dividend behind the 902 and repeat the process: 9022 / 945

Moving on to step 6:
945 goes into 9022 9 times with a remainder of 517.
The next digit of our result is 9. 
Result so far: 419.0
Subtracting 8505 from 9022 leaves us with 517.
Take the next digit (1) from the dividend and append it to 517, then repeat: 5171 / 945

On to step 7:
When dividing 5171 by 945, we get 5 with a remainder of 446.
Record the quotient 5 as the next digit in the result. 
Result so far: 4195.0
Subtracting 4725 from 5171 leaves us with 446.
Fetch the next digit (6) from the dividend, attach it to 446 and continue: 4466 / 945

Let's proceed to step 8:
When dividing 4466 by 945, we get 4 with a remainder of 686.
The next digit of our result is 4. 
Result so far: 41954.0
Subtract 3780 from 4466 to get 686.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6860, and continue the process.

Let's proceed to step 9:
The number 945 fits into 6860 7 times, leaving a remainder of 245.
Record the quotient 7 as the next digit in the result. 
Result so far: 41954.7
The remainder is 245 after subtracting 6615 from 6860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Moving on to step 10:
If we divide 2450 by 945, we get 2 and a remainder of 560.
Put 2 as the next digit of the answer. 
Result so far: 41954.72
Subtract 1890 from 2450 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

On to step 11:
945 goes into 5600 5 times with a remainder of 875.
Record the quotient 5 as the next digit in the result. 
Result so far: 41954.725
If we subtract 4725 from 5600, we get 875.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8750, and continue the process.

Step 12:
945 can be fit into 8750 9 times, resulting in a remainder of 245.
The number 9 becomes the next digit in our result. 
Result so far: 41954.7259
The remainder is 245 after subtracting 8505 from 8750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Step 13:
2450 divided by 945 is 2 with a remainder of 560.
Record the quotient 2 as the next digit in the result. 
Result so far: 41954.72592
Subtract 1890 from 2450 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 14:
5600 divided by 945 is 5 with a remainder of 875.
Record the quotient 5 as the next digit in the result. 
Result so far: 41954.725925
Subtracting 4725 from 5600 leaves us with 875.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8750, and continue the process.

Let's proceed to step 15:
8750 divided by 945 is 9 with a remainder of 245.
Put 9 as the next digit of the answer. 
Result so far: 41954.7259259
Subtract 8505 from 8750 to get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

On to step 16:
If we divide 2450 by 945, we get 2 and a remainder of 560.
Write down 2 as next digit of the result. 
Result so far: 41954.72592592
If we take 1890 away from 2450, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Our division results in 41954.72592592 with a remaining 5.6e-07.
