83553378 divided by 72 
We're looking to find how many times 72 goes into 83553378.

Step 1:
When dividing 8 by 72, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 72

Moving on to step 2:
When dividing 83 by 72, we get 1 with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 72 from 83 leaves us with 11.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 72

Advancing to step 3:
72 can be fit into 115 1 times, resulting in a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 72 away from 115, we end up with 43.
Include the next digit (5) from the dividend after 43, then repeat: 435 / 72

Advancing to step 4:
If we divide 435 by 72, we get 6 and a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 116.0
If we take 432 away from 435, we end up with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 72

On to step 5:
72 goes into 33 0 times with a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 1160.0
Subtract 0 from 33 to get 33.
Take the next digit (3) from the dividend and append it to 33, then repeat: 333 / 72

Step 6:
If we divide 333 by 72, we get 4 and a remainder of 45.
Put 4 as the next digit of the answer. 
Result so far: 11604.0
Deduct 288 from 333 and we're left with 45.
Include the next digit (7) from the dividend after 45, then repeat: 457 / 72

Advancing to step 7:
457 divided by 72 is 6 with a remainder of 25.
Write down 6 as next digit of the result. 
Result so far: 116046.0
Deduct 432 from 457 and we're left with 25.
Fetch the next digit (8) from the dividend, attach it to 25 and continue: 258 / 72

Advancing to step 8:
72 can be fit into 258 3 times, resulting in a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 1160463.0
If we subtract 216 from 258, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 9:
When dividing 420 by 72, we get 5 with a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 1160463.5
The remainder is 60 after subtracting 360 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 10:
When dividing 600 by 72, we get 8 with a remainder of 24.
The next digit of our result is 8. 
Result so far: 1160463.58
If we subtract 576 from 600, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 11:
240 divided by 72 is 3 with a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 1160463.583
If we subtract 216 from 240, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 12:
The number 72 fits into 240 3 times, leaving a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 1160463.5833
Subtract 216 from 240 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 1160463.5833 and a remainder of 0.00024.
