98566542 divided by 166 
We want to divide 98566542 by 166.

Step 1:
166 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 166

Let's proceed to step 2:
166 goes into 98 0 times with a remainder of 98.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 98 leaves us with 98.
Bring next digit (5) of the dividend behind the 98 and repeat the process: 985 / 166

Going ahead to step 3:
If we divide 985 by 166, we get 5 and a remainder of 155.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 830 from 985, we get 155.
Grab the next digit (6) from the dividend, add it to 155, then carry on: 1556 / 166

Advancing to step 4:
The number 166 fits into 1556 9 times, leaving a remainder of 62.
Record the quotient 9 as the next digit in the result. 
Result so far: 59.0
Deduct 1494 from 1556 and we're left with 62.
Bring next digit (6) of the dividend behind the 62 and repeat the process: 626 / 166

Moving on to step 5:
166 goes into 626 3 times with a remainder of 128.
The next digit of our result is 3. 
Result so far: 593.0
The remainder is 128 after subtracting 498 from 626.
Fetch the next digit (5) from the dividend, attach it to 128 and continue: 1285 / 166

Step 6:
When dividing 1285 by 166, we get 7 with a remainder of 123.
Write down 7 as next digit of the result. 
Result so far: 5937.0
If we take 1162 away from 1285, we end up with 123.
Include the next digit (4) from the dividend after 123, then repeat: 1234 / 166

On to step 7:
1234 divided by 166 is 7 with a remainder of 72.
The number 7 becomes the next digit in our result. 
Result so far: 59377.0
If we take 1162 away from 1234, we end up with 72.
Fetch the next digit (2) from the dividend, attach it to 72 and continue: 722 / 166

Moving on to step 8:
166 can be fit into 722 4 times, resulting in a remainder of 58.
The number 4 becomes the next digit in our result. 
Result so far: 593774.0
The remainder is 58 after subtracting 664 from 722.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 9:
580 divided by 166 is 3 with a remainder of 82.
Put 3 as the next digit of the answer. 
Result so far: 593774.3
Deduct 498 from 580 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 10:
The number 166 fits into 820 4 times, leaving a remainder of 156.
Record the quotient 4 as the next digit in the result. 
Result so far: 593774.34
Deduct 664 from 820 and we're left with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

On to step 11:
166 goes into 1560 9 times with a remainder of 66.
The number 9 becomes the next digit in our result. 
Result so far: 593774.349
Subtracting 1494 from 1560 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 12:
166 goes into 660 3 times with a remainder of 162.
Record the quotient 3 as the next digit in the result. 
Result so far: 593774.3493
Deduct 498 from 660 and we're left with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Moving on to step 13:
1620 divided by 166 is 9 with a remainder of 126.
The next digit of our result is 9. 
Result so far: 593774.34939
Subtract 1494 from 1620 to get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 14:
166 can be fit into 1260 7 times, resulting in a remainder of 98.
Put 7 as the next digit of the answer. 
Result so far: 593774.349397
Deduct 1162 from 1260 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 15:
980 divided by 166 is 5 with a remainder of 150.
Put 5 as the next digit of the answer. 
Result so far: 593774.3493975
Subtracting 830 from 980 leaves us 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.

Step 16:
1500 divided by 166 is 9 with a remainder of 6.
The next digit of our result is 9. 
Result so far: 593774.34939759
If we take 1494 away from 1500, we end up 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.

The final result is 593774.34939759 with a remainder of 6e-09.
