53591487 ÷ 616 
Let's see how many times 616 fits into 53591487.

On to step 1:
When dividing 5 by 616, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 616

Moving on to step 2:
616 can be fit into 53 0 times, resulting in a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 53 after subtracting 0 from 53.
Include the next digit (5) from the dividend after 53, then repeat: 535 / 616

Advancing to step 3:
The number 616 fits into 535 0 times, leaving a remainder of 535.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 535 to get 535.
Take the next digit (9) from the dividend and append it to 535, then repeat: 5359 / 616

Let's proceed to step 4:
The number 616 fits into 5359 8 times, leaving a remainder of 431.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 4928 from 5359 to get 431.
Take the next digit (1) from the dividend and append it to 431, then repeat: 4311 / 616

On to step 5:
The number 616 fits into 4311 6 times, leaving a remainder of 615.
The next digit of our result is 6. 
Result so far: 86.0
If we take 3696 away from 4311, we end up with 615.
Include the next digit (4) from the dividend after 615, then repeat: 6154 / 616

Step 6:
616 can be fit into 6154 9 times, resulting in a remainder of 610.
Put 9 as the next digit of the answer. 
Result so far: 869.0
If we take 5544 away from 6154, we end up with 610.
Grab the next digit (8) from the dividend, add it to 610, then carry on: 6108 / 616

Advancing to step 7:
616 can be fit into 6108 9 times, resulting in a remainder of 564.
Record the quotient 9 as the next digit in the result. 
Result so far: 8699.0
If we take 5544 away from 6108, we end up with 564.
Fetch the next digit (7) from the dividend, attach it to 564 and continue: 5647 / 616

Let's proceed to step 8:
5647 divided by 616 is 9 with a remainder of 103.
Use 9 as the next digit of our solution. 
Result so far: 86999.0
If we subtract 5544 from 5647, we get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Advancing to step 9:
616 goes into 1030 1 times with a remainder of 414.
The number 1 becomes the next digit in our result. 
Result so far: 86999.1
Subtracting 616 from 1030 leaves us with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

On to step 10:
When dividing 4140 by 616, we get 6 with a remainder of 444.
The number 6 becomes the next digit in our result. 
Result so far: 86999.16
Deduct 3696 from 4140 and we're left with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Moving on to step 11:
The number 616 fits into 4440 7 times, leaving a remainder of 128.
The number 7 becomes the next digit in our result. 
Result so far: 86999.167
Subtract 4312 from 4440 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 12:
616 can be fit into 1280 2 times, resulting in a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 86999.1672
Deduct 1232 from 1280 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 13:
The number 616 fits into 480 0 times, leaving a remainder of 480.
Write down 0 as next digit of the result. 
Result so far: 86999.1672
Deduct 0 from 480 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 14:
If we divide 4800 by 616, we get 7 and a remainder of 488.
Write down 7 as next digit of the result. 
Result so far: 86999.167207
Subtract 4312 from 4800 to get 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Let's proceed to step 15:
When dividing 4880 by 616, we get 7 with a remainder of 568.
The number 7 becomes the next digit in our result. 
Result so far: 86999.1672077
Subtract 4312 from 4880 to get 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

After the division, we end up with 86999.1672077 and a remainder of 5.68e-06.
