Let's divide 59173987 by 821
We want to figure out the number of times 59173987 can be divided by 821.

Going ahead to step 1:
The number 821 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 821

Moving on to step 2:
The number 821 fits into 59 0 times, leaving a remainder of 59.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 59 to get 59.
Fetch the next digit (1) from the dividend, attach it to 59 and continue: 591 / 821

Step 3:
591 divided by 821 is 0 with a remainder of 591.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 591, we get 591.
Append the next digit (7) from the dividend to 591 and continue with: 5917 / 821

On to step 4:
821 can be fit into 5917 7 times, resulting in a remainder of 170.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 5747 from 5917 to get 170.
Bring next digit (3) of the dividend behind the 170 and repeat the process: 1703 / 821

Moving on to step 5:
821 can be fit into 1703 2 times, resulting in a remainder of 61.
The next digit of our result is 2. 
Result so far: 72.0
Subtracting 1642 from 1703 leaves us with 61.
Grab the next digit (9) from the dividend, add it to 61, then carry on: 619 / 821

Going ahead to step 6:
The number 821 fits into 619 0 times, leaving a remainder of 619.
Record the quotient 0 as the next digit in the result. 
Result so far: 720.0
Subtracting 0 from 619 leaves us with 619.
Fetch the next digit (8) from the dividend, attach it to 619 and continue: 6198 / 821

Advancing to step 7:
When dividing 6198 by 821, we get 7 with a remainder of 451.
Put 7 as the next digit of the answer. 
Result so far: 7207.0
Subtract 5747 from 6198 to get 451.
Fetch the next digit (7) from the dividend, attach it to 451 and continue: 4517 / 821

Step 8:
When dividing 4517 by 821, we get 5 with a remainder of 412.
Record the quotient 5 as the next digit in the result. 
Result so far: 72075.0
If we take 4105 away from 4517, we end up with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Step 9:
The number 821 fits into 4120 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 72075.5
The remainder is 15 after subtracting 4105 from 4120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 10:
150 divided by 821 is 0 with a remainder of 150.
Put 0 as the next digit of the answer. 
Result so far: 72075.5
If we subtract 0 from 150, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 11:
If we divide 1500 by 821, we get 1 and a remainder of 679.
Put 1 as the next digit of the answer. 
Result so far: 72075.501
The remainder is 679 after subtracting 821 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6790, and continue the process.

Let's proceed to step 12:
When dividing 6790 by 821, we get 8 with a remainder of 222.
The number 8 becomes the next digit in our result. 
Result so far: 72075.5018
If we subtract 6568 from 6790, we get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Advancing to step 13:
821 can be fit into 2220 2 times, resulting in a remainder of 578.
Use 2 as the next digit of our solution. 
Result so far: 72075.50182
The remainder is 578 after subtracting 1642 from 2220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Going ahead to step 14:
The number 821 fits into 5780 7 times, leaving a remainder of 33.
Use 7 as the next digit of our solution. 
Result so far: 72075.501827
Subtracting 5747 from 5780 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 15:
821 can be fit into 330 0 times, resulting in a remainder of 330.
The number 0 becomes the next digit in our result. 
Result so far: 72075.501827
Deduct 0 from 330 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Moving on to step 16:
The number 821 fits into 3300 4 times, leaving a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 72075.50182704
Subtracting 3284 from 3300 leaves us 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.

After the division, we end up with 72075.50182704 and a remainder of 1.6e-08.
