We look at the division of 69723988 by 648 
We want to figure out the number of times 69723988 can be divided by 648.

Going ahead to step 1:
6 divided by 648 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 648

On to step 2:
648 goes into 69 0 times with a remainder of 69.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 69 leaves us with 69.
Grab the next digit (7) from the dividend, add it to 69, then carry on: 697 / 648

Let's proceed to step 3:
648 goes into 697 1 times with a remainder of 49.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 648 from 697, we get 49.
Take the next digit (2) from the dividend and append it to 49, then repeat: 492 / 648

Let's proceed to step 4:
648 goes into 492 0 times with a remainder of 492.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 492 to get 492.
Take the next digit (3) from the dividend and append it to 492, then repeat: 4923 / 648

Going ahead to step 5:
When dividing 4923 by 648, we get 7 with a remainder of 387.
The number 7 becomes the next digit in our result. 
Result so far: 107.0
Deduct 4536 from 4923 and we're left with 387.
Take the next digit (9) from the dividend and append it to 387, then repeat: 3879 / 648

On to step 6:
648 can be fit into 3879 5 times, resulting in a remainder of 639.
The number 5 becomes the next digit in our result. 
Result so far: 1075.0
Subtracting 3240 from 3879 leaves us with 639.
Take the next digit (8) from the dividend and append it to 639, then repeat: 6398 / 648

Step 7:
If we divide 6398 by 648, we get 9 and a remainder of 566.
Record the quotient 9 as the next digit in the result. 
Result so far: 10759.0
The remainder is 566 after subtracting 5832 from 6398.
Append the next digit (8) from the dividend to 566 and continue with: 5668 / 648

Advancing to step 8:
If we divide 5668 by 648, we get 8 and a remainder of 484.
The next digit of our result is 8. 
Result so far: 107598.0
If we subtract 5184 from 5668, we get 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Going ahead to step 9:
648 can be fit into 4840 7 times, resulting in a remainder of 304.
The next digit of our result is 7. 
Result so far: 107598.7
Subtract 4536 from 4840 to get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Step 10:
3040 divided by 648 is 4 with a remainder of 448.
Put 4 as the next digit of the answer. 
Result so far: 107598.74
Deduct 2592 from 3040 and we're left with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

On to step 11:
If we divide 4480 by 648, we get 6 and a remainder of 592.
Write down 6 as next digit of the result. 
Result so far: 107598.746
Subtracting 3888 from 4480 leaves us with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Step 12:
If we divide 5920 by 648, we get 9 and a remainder of 88.
The next digit of our result is 9. 
Result so far: 107598.7469
Subtract 5832 from 5920 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 13:
648 goes into 880 1 times with a remainder of 232.
The number 1 becomes the next digit in our result. 
Result so far: 107598.74691
Subtracting 648 from 880 leaves us with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

On to step 14:
648 can be fit into 2320 3 times, resulting in a remainder of 376.
Record the quotient 3 as the next digit in the result. 
Result so far: 107598.746913
If we take 1944 away from 2320, we end up with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Moving on to step 15:
If we divide 3760 by 648, we get 5 and a remainder of 520.
The number 5 becomes the next digit in our result. 
Result so far: 107598.7469135
Subtract 3240 from 3760 to get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Moving on to step 16:
648 goes into 5200 8 times with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 107598.74691358
Subtract 5184 from 5200 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 107598.74691358 with a remaining 1.6e-08.
