69564117 ÷ 644 
We want to figure out the number of times 69564117 can be divided by 644.

Step 1:
The number 644 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 644

Advancing to step 2:
When dividing 69 by 644, we get 0 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.
Bring next digit (5) of the dividend behind the 69 and repeat the process: 695 / 644

Moving on to step 3:
If we divide 695 by 644, we get 1 and a remainder of 51.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 644 from 695 leaves us with 51.
Grab the next digit (6) from the dividend, add it to 51, then carry on: 516 / 644

Moving on to step 4:
When dividing 516 by 644, we get 0 with a remainder of 516.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 516 leaves us with 516.
Bring next digit (4) of the dividend behind the 516 and repeat the process: 5164 / 644

On to step 5:
644 goes into 5164 8 times with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 108.0
Subtract 5152 from 5164 to get 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 644

Moving on to step 6:
If we divide 121 by 644, we get 0 and a remainder of 121.
Record the quotient 0 as the next digit in the result. 
Result so far: 1080.0
Subtracting 0 from 121 leaves us with 121.
Grab the next digit (1) from the dividend, add it to 121, then carry on: 1211 / 644

Advancing to step 7:
The number 644 fits into 1211 1 times, leaving a remainder of 567.
Write down 1 as next digit of the result. 
Result so far: 10801.0
If we take 644 away from 1211, we end up with 567.
Fetch the next digit (7) from the dividend, attach it to 567 and continue: 5677 / 644

Step 8:
The number 644 fits into 5677 8 times, leaving a remainder of 525.
Put 8 as the next digit of the answer. 
Result so far: 108018.0
If we take 5152 away from 5677, we end up with 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Let's proceed to step 9:
The number 644 fits into 5250 8 times, leaving a remainder of 98.
Use 8 as the next digit of our solution. 
Result so far: 108018.8
If we take 5152 away from 5250, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Let's proceed to step 10:
644 can be fit into 980 1 times, resulting in a remainder of 336.
Put 1 as the next digit of the answer. 
Result so far: 108018.81
If we subtract 644 from 980, we get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Let's proceed to step 11:
The number 644 fits into 3360 5 times, leaving a remainder of 140.
Use 5 as the next digit of our solution. 
Result so far: 108018.815
The remainder is 140 after subtracting 3220 from 3360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 12:
644 can be fit into 1400 2 times, resulting in a remainder of 112.
Write down 2 as next digit of the result. 
Result so far: 108018.8152
Subtracting 1288 from 1400 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 13:
1120 divided by 644 is 1 with a remainder of 476.
Put 1 as the next digit of the answer. 
Result so far: 108018.81521
Subtract 644 from 1120 to get 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

On to step 14:
If we divide 4760 by 644, we get 7 and a remainder of 252.
Use 7 as the next digit of our solution. 
Result so far: 108018.815217
Subtracting 4508 from 4760 leaves us with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Step 15:
644 can be fit into 2520 3 times, resulting in a remainder of 588.
Use 3 as the next digit of our solution. 
Result so far: 108018.8152173
Subtracting 1932 from 2520 leaves us with 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Going ahead to step 16:
If we divide 5880 by 644, we get 9 and a remainder of 84.
The next digit of our result is 9. 
Result so far: 108018.81521739
If we take 5796 away from 5880, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Our division results in 108018.81521739 with a remaining 8.4e-08.
