We look at the division of 37951881 by 648 
Let's see how many times 648 fits into 37951881.

Advancing to step 1:
648 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 648

Step 2:
When dividing 37 by 648, we get 0 with a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 37 to get 37.
Grab the next digit (9) from the dividend, add it to 37, then carry on: 379 / 648

Moving on to step 3:
648 goes into 379 0 times with a remainder of 379.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 379 after subtracting 0 from 379.
Take the next digit (5) from the dividend and append it to 379, then repeat: 3795 / 648

Advancing to step 4:
648 goes into 3795 5 times with a remainder of 555.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 3240 from 3795, we get 555.
Fetch the next digit (1) from the dividend, attach it to 555 and continue: 5551 / 648

Let's proceed to step 5:
5551 divided by 648 is 8 with a remainder of 367.
The number 8 becomes the next digit in our result. 
Result so far: 58.0
Subtracting 5184 from 5551 leaves us with 367.
Include the next digit (8) from the dividend after 367, then repeat: 3678 / 648

Let's proceed to step 6:
The number 648 fits into 3678 5 times, leaving a remainder of 438.
Write down 5 as next digit of the result. 
Result so far: 585.0
If we subtract 3240 from 3678, we get 438.
Grab the next digit (8) from the dividend, add it to 438, then carry on: 4388 / 648

Going ahead to step 7:
If we divide 4388 by 648, we get 6 and a remainder of 500.
Write down 6 as next digit of the result. 
Result so far: 5856.0
Deduct 3888 from 4388 and we're left with 500.
Grab the next digit (1) from the dividend, add it to 500, then carry on: 5001 / 648

On to step 8:
If we divide 5001 by 648, we get 7 and a remainder of 465.
Use 7 as the next digit of our solution. 
Result so far: 58567.0
If we subtract 4536 from 5001, we get 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Advancing to step 9:
When dividing 4650 by 648, we get 7 with a remainder of 114.
The next digit of our result is 7. 
Result so far: 58567.7
If we subtract 4536 from 4650, we get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Let's proceed to step 10:
1140 divided by 648 is 1 with a remainder of 492.
The next digit of our result is 1. 
Result so far: 58567.71
The remainder is 492 after subtracting 648 from 1140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Going ahead to step 11:
648 can be fit into 4920 7 times, resulting in a remainder of 384.
The next digit of our result is 7. 
Result so far: 58567.717
The remainder is 384 after subtracting 4536 from 4920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 12:
The number 648 fits into 3840 5 times, leaving a remainder of 600.
Write down 5 as next digit of the result. 
Result so far: 58567.7175
Subtracting 3240 from 3840 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Let's proceed to step 13:
648 can be fit into 6000 9 times, resulting in a remainder of 168.
Use 9 as the next digit of our solution. 
Result so far: 58567.71759
Deduct 5832 from 6000 and we're left with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Let's proceed to step 14:
The number 648 fits into 1680 2 times, leaving a remainder of 384.
Put 2 as the next digit of the answer. 
Result so far: 58567.717592
If we subtract 1296 from 1680, we get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 15:
The number 648 fits into 3840 5 times, leaving a remainder of 600.
Write down 5 as next digit of the result. 
Result so far: 58567.7175925
Subtract 3240 from 3840 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 16:
648 can be fit into 6000 9 times, resulting in a remainder of 168.
Record the quotient 9 as the next digit in the result. 
Result so far: 58567.71759259
If we take 5832 away from 6000, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

The final result is 58567.71759259 with a remainder of 1.68e-07.
