Let's divide 53873860 by 945
Let's see how many times 945 fits into 53873860.

Advancing to step 1:
The number 945 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 945

Going ahead to step 2:
945 goes into 53 0 times with a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Take the next digit (8) from the dividend and append it to 53, then repeat: 538 / 945

Let's proceed to step 3:
945 can be fit into 538 0 times, resulting in a remainder of 538.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 538 to get 538.
Bring next digit (7) of the dividend behind the 538 and repeat the process: 5387 / 945

Advancing to step 4:
5387 divided by 945 is 5 with a remainder of 662.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 4725 from 5387, we get 662.
Append the next digit (3) from the dividend to 662 and continue with: 6623 / 945

Advancing to step 5:
If we divide 6623 by 945, we get 7 and a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 57.0
If we subtract 6615 from 6623, we get 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 945

Advancing to step 6:
If we divide 88 by 945, we get 0 and a remainder of 88.
Write down 0 as next digit of the result. 
Result so far: 570.0
Subtract 0 from 88 to get 88.
Append the next digit (6) from the dividend to 88 and continue with: 886 / 945

Advancing to step 7:
If we divide 886 by 945, we get 0 and a remainder of 886.
Write down 0 as next digit of the result. 
Result so far: 5700.0
Subtracting 0 from 886 leaves us with 886.
Include the next digit (0) from the dividend after 886, then repeat: 8860 / 945

Let's proceed to step 8:
945 goes into 8860 9 times with a remainder of 355.
The next digit of our result is 9. 
Result so far: 57009.0
Subtracting 8505 from 8860 leaves us with 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Moving on to step 9:
If we divide 3550 by 945, we get 3 and a remainder of 715.
The next digit of our result is 3. 
Result so far: 57009.3
The remainder is 715 after subtracting 2835 from 3550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7150, and continue the process.

Advancing to step 10:
If we divide 7150 by 945, we get 7 and a remainder of 535.
The next digit of our result is 7. 
Result so far: 57009.37
Deduct 6615 from 7150 and we're left with 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Let's proceed to step 11:
The number 945 fits into 5350 5 times, leaving a remainder of 625.
Use 5 as the next digit of our solution. 
Result so far: 57009.375
If we subtract 4725 from 5350, we get 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Going ahead to step 12:
6250 divided by 945 is 6 with a remainder of 580.
Put 6 as the next digit of the answer. 
Result so far: 57009.3756
Deduct 5670 from 6250 and we're left with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Advancing to step 13:
945 goes into 5800 6 times with a remainder of 130.
Use 6 as the next digit of our solution. 
Result so far: 57009.37566
Subtract 5670 from 5800 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

After the division, we end up with 57009.37566 and a remainder of 0.00013.
