87021666 ÷ 498 
Our goal is to divide 87021666 by 498.

Step 1:
The number 498 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 498

Advancing to step 2:
498 can be fit into 87 0 times, resulting in a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Fetch the next digit (0) from the dividend, attach it to 87 and continue: 870 / 498

Step 3:
When dividing 870 by 498, we get 1 with a remainder of 372.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 498 away from 870, we end up with 372.
Bring next digit (2) of the dividend behind the 372 and repeat the process: 3722 / 498

On to step 4:
When dividing 3722 by 498, we get 7 with a remainder of 236.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Deduct 3486 from 3722 and we're left with 236.
Grab the next digit (1) from the dividend, add it to 236, then carry on: 2361 / 498

Let's proceed to step 5:
If we divide 2361 by 498, we get 4 and a remainder of 369.
Write down 4 as next digit of the result. 
Result so far: 174.0
Deduct 1992 from 2361 and we're left with 369.
Fetch the next digit (6) from the dividend, attach it to 369 and continue: 3696 / 498

Going ahead to step 6:
If we divide 3696 by 498, we get 7 and a remainder of 210.
Put 7 as the next digit of the answer. 
Result so far: 1747.0
If we subtract 3486 from 3696, we get 210.
Take the next digit (6) from the dividend and append it to 210, then repeat: 2106 / 498

Going ahead to step 7:
The number 498 fits into 2106 4 times, leaving a remainder of 114.
The next digit of our result is 4. 
Result so far: 17474.0
Deduct 1992 from 2106 and we're left with 114.
Bring next digit (6) of the dividend behind the 114 and repeat the process: 1146 / 498

Moving on to step 8:
When dividing 1146 by 498, we get 2 with a remainder of 150.
Record the quotient 2 as the next digit in the result. 
Result so far: 174742.0
If we take 996 away from 1146, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 9:
498 can be fit into 1500 3 times, resulting in a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 174742.3
Deduct 1494 from 1500 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 10:
When dividing 60 by 498, we get 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 174742.3
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 11:
If we divide 600 by 498, we get 1 and a remainder of 102.
Write down 1 as next digit of the result. 
Result so far: 174742.301
If we take 498 away from 600, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 12:
If we divide 1020 by 498, we get 2 and a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 174742.3012
Subtracting 996 from 1020 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 13:
The number 498 fits into 240 0 times, leaving a remainder of 240.
Put 0 as the next digit of the answer. 
Result so far: 174742.3012
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 14:
When dividing 2400 by 498, we get 4 with a remainder of 408.
Record the quotient 4 as the next digit in the result. 
Result so far: 174742.301204
Deduct 1992 from 2400 and we're left with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Let's proceed to step 15:
When dividing 4080 by 498, we get 8 with a remainder of 96.
Write down 8 as next digit of the result. 
Result so far: 174742.3012048
Subtracting 3984 from 4080 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 16:
960 divided by 498 is 1 with a remainder of 462.
Put 1 as the next digit of the answer. 
Result so far: 174742.30120481
If we take 498 away from 960, we end up with 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

After the division, we end up with 174742.30120481 and a remainder of 4.62e-07.
