We divide 420997 by 87
We're looking to find how many times 87 goes into 420997.

Step 1:
The number 87 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 87

Let's proceed to step 2:
When dividing 42 by 87, we get 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Include the next digit (0) from the dividend after 42, then repeat: 420 / 87

Step 3:
If we divide 420 by 87, we get 4 and a remainder of 72.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 348 away from 420, we end up with 72.
Bring next digit (9) of the dividend behind the 72 and repeat the process: 729 / 87

Let's proceed to step 4:
87 can be fit into 729 8 times, resulting in a remainder of 33.
Write down 8 as next digit of the result. 
Result so far: 48.0
Deduct 696 from 729 and we're left with 33.
Take the next digit (9) from the dividend and append it to 33, then repeat: 339 / 87

Moving on to step 5:
The number 87 fits into 339 3 times, leaving a remainder of 78.
Use 3 as the next digit of our solution. 
Result so far: 483.0
Deduct 261 from 339 and we're left with 78.
Include the next digit (7) from the dividend after 78, then repeat: 787 / 87

On to step 6:
87 can be fit into 787 9 times, resulting in a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 4839.0
The remainder is 4 after subtracting 783 from 787.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
87 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 4839.0
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
The number 87 fits into 400 4 times, leaving a remainder of 52.
Put 4 as the next digit of the answer. 
Result so far: 4839.04
If we subtract 348 from 400, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 9:
When dividing 520 by 87, we get 5 with a remainder of 85.
The next digit of our result is 5. 
Result so far: 4839.045
If we subtract 435 from 520, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 10:
If we divide 850 by 87, we get 9 and a remainder of 67.
Record the quotient 9 as the next digit in the result. 
Result so far: 4839.0459
The remainder is 67 after subtracting 783 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 11:
87 can be fit into 670 7 times, resulting in a remainder of 61.
Use 7 as the next digit of our solution. 
Result so far: 4839.04597
The remainder is 61 after subtracting 609 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 12:
The number 87 fits into 610 7 times, leaving a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 4839.045977
If we subtract 609 from 610, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The quotient of the division is 4839.045977, and the remainder is 1e-07.
