13945570 divided by 216 
We want to figure out the number of times 13945570 can be divided by 216.

Advancing to step 1:
216 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 216

Advancing to step 2:
If we divide 13 by 216, we get 0 and a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 216

Let's proceed to step 3:
When dividing 139 by 216, we get 0 with a remainder of 139.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 139, we end up with 139.
Bring next digit (4) of the dividend behind the 139 and repeat the process: 1394 / 216

Going ahead to step 4:
216 can be fit into 1394 6 times, resulting in a remainder of 98.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 1296 from 1394 to get 98.
Append the next digit (5) from the dividend to 98 and continue with: 985 / 216

Moving on to step 5:
When dividing 985 by 216, we get 4 with a remainder of 121.
Put 4 as the next digit of the answer. 
Result so far: 64.0
If we subtract 864 from 985, we get 121.
Include the next digit (5) from the dividend after 121, then repeat: 1215 / 216

Advancing to step 6:
When dividing 1215 by 216, we get 5 with a remainder of 135.
Record the quotient 5 as the next digit in the result. 
Result so far: 645.0
If we subtract 1080 from 1215, we get 135.
Grab the next digit (7) from the dividend, add it to 135, then carry on: 1357 / 216

Going ahead to step 7:
When dividing 1357 by 216, we get 6 with a remainder of 61.
Write down 6 as next digit of the result. 
Result so far: 6456.0
Subtract 1296 from 1357 to get 61.
Fetch the next digit (0) from the dividend, attach it to 61 and continue: 610 / 216

Step 8:
When dividing 610 by 216, we get 2 with a remainder of 178.
Put 2 as the next digit of the answer. 
Result so far: 64562.0
If we subtract 432 from 610, we get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Advancing to step 9:
If we divide 1780 by 216, we get 8 and a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 64562.8
Subtracting 1728 from 1780 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 10:
520 divided by 216 is 2 with a remainder of 88.
The next digit of our result is 2. 
Result so far: 64562.82
If we subtract 432 from 520, we 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.

Let's proceed to step 11:
216 goes into 880 4 times with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 64562.824
If we take 864 away from 880, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 12:
The number 216 fits into 160 0 times, leaving a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 64562.824
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 13:
1600 divided by 216 is 7 with a remainder of 88.
The next digit of our result is 7. 
Result so far: 64562.82407
If we subtract 1512 from 1600, we 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.

Moving on to step 14:
The number 216 fits into 880 4 times, leaving a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 64562.824074
Deduct 864 from 880 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 15:
The number 216 fits into 160 0 times, leaving a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 64562.824074
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 16:
The number 216 fits into 1600 7 times, leaving a remainder of 88.
Record the quotient 7 as the next digit in the result. 
Result so far: 64562.82407407
Subtracting 1512 from 1600 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

The final result is 64562.82407407 with a remainder of 8.8e-08.
