We're dividing 53661046 by 87 
We want to figure out the number of times 53661046 can be divided by 87.

Advancing to step 1:
5 divided by 87 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 87

On to step 2:
87 can be fit into 53 0 times, resulting in a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Bring next digit (6) of the dividend behind the 53 and repeat the process: 536 / 87

Let's proceed to step 3:
The number 87 fits into 536 6 times, leaving a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 14 after subtracting 522 from 536.
Include the next digit (6) from the dividend after 14, then repeat: 146 / 87

Moving on to step 4:
When dividing 146 by 87, we get 1 with a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 61.0
If we subtract 87 from 146, we get 59.
Include the next digit (1) from the dividend after 59, then repeat: 591 / 87

Going ahead to step 5:
If we divide 591 by 87, we get 6 and a remainder of 69.
Put 6 as the next digit of the answer. 
Result so far: 616.0
The remainder is 69 after subtracting 522 from 591.
Append the next digit (0) from the dividend to 69 and continue with: 690 / 87

On to step 6:
The number 87 fits into 690 7 times, leaving a remainder of 81.
The number 7 becomes the next digit in our result. 
Result so far: 6167.0
If we take 609 away from 690, we end up with 81.
Include the next digit (4) from the dividend after 81, then repeat: 814 / 87

Moving on to step 7:
87 goes into 814 9 times with a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 61679.0
If we subtract 783 from 814, we get 31.
Append the next digit (6) from the dividend to 31 and continue with: 316 / 87

Advancing to step 8:
When dividing 316 by 87, we get 3 with a remainder of 55.
Put 3 as the next digit of the answer. 
Result so far: 616793.0
Subtract 261 from 316 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 9:
87 can be fit into 550 6 times, resulting in a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 616793.6
Subtracting 522 from 550 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 10:
87 goes into 280 3 times with a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 616793.63
Subtract 261 from 280 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 11:
If we divide 190 by 87, we get 2 and a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 616793.632
The remainder is 16 after subtracting 174 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 12:
160 divided by 87 is 1 with a remainder of 73.
Put 1 as the next digit of the answer. 
Result so far: 616793.6321
Subtract 87 from 160 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 13:
87 can be fit into 730 8 times, resulting in a remainder of 34.
Record the quotient 8 as the next digit in the result. 
Result so far: 616793.63218
If we subtract 696 from 730, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 14:
The number 87 fits into 340 3 times, leaving a remainder of 79.
The number 3 becomes the next digit in our result. 
Result so far: 616793.632183
Subtracting 261 from 340 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 15:
If we divide 790 by 87, we get 9 and a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 616793.6321839
The remainder is 7 after subtracting 783 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 16:
The number 87 fits into 70 0 times, leaving a remainder of 70.
The next digit of our result is 0. 
Result so far: 616793.6321839
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The quotient of the division is 616793.6321839, and the remainder is 7e-08.
