69745889 divided by 64 
Our goal is to divide 69745889 by 64.

Step 1:
The number 64 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 64

Going ahead to step 2:
If we divide 69 by 64, we get 1 and a remainder of 5.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 64 from 69 to get 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 64

On to step 3:
64 goes into 57 0 times with a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 57, we get 57.
Take the next digit (4) from the dividend and append it to 57, then repeat: 574 / 64

Moving on to step 4:
574 divided by 64 is 8 with a remainder of 62.
Record the quotient 8 as the next digit in the result. 
Result so far: 108.0
The remainder is 62 after subtracting 512 from 574.
Include the next digit (5) from the dividend after 62, then repeat: 625 / 64

Going ahead to step 5:
64 goes into 625 9 times with a remainder of 49.
Record the quotient 9 as the next digit in the result. 
Result so far: 1089.0
If we subtract 576 from 625, we get 49.
Grab the next digit (8) from the dividend, add it to 49, then carry on: 498 / 64

Let's proceed to step 6:
64 goes into 498 7 times with a remainder of 50.
Put 7 as the next digit of the answer. 
Result so far: 10897.0
Subtract 448 from 498 to get 50.
Grab the next digit (8) from the dividend, add it to 50, then carry on: 508 / 64

Going ahead to step 7:
508 divided by 64 is 7 with a remainder of 60.
The number 7 becomes the next digit in our result. 
Result so far: 108977.0
Deduct 448 from 508 and we're left with 60.
Fetch the next digit (9) from the dividend, attach it to 60 and continue: 609 / 64

On to step 8:
The number 64 fits into 609 9 times, leaving a remainder of 33.
Put 9 as the next digit of the answer. 
Result so far: 1089779.0
If we subtract 576 from 609, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 9:
If we divide 330 by 64, we get 5 and a remainder of 10.
The next digit of our result is 5. 
Result so far: 1089779.5
Subtracting 320 from 330 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
If we divide 100 by 64, we get 1 and a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 1089779.51
If we take 64 away from 100, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 11:
64 can be fit into 360 5 times, resulting in a remainder of 40.
The next digit of our result is 5. 
Result so far: 1089779.515
If we subtract 320 from 360, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
64 goes into 400 6 times with a remainder of 16.
The next digit of our result is 6. 
Result so far: 1089779.5156
If we subtract 384 from 400, we 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.

Step 13:
64 can be fit into 160 2 times, resulting in a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 1089779.51562
If we subtract 128 from 160, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 14:
320 divided by 64 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 1089779.515625
If we take 320 away from 320, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 15:
64 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1089779.515625
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 16:
If we divide 0 by 64, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1089779.515625
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 1089779.515625 with a balance of 0.0.
