66418860 divided by 98 
Our goal is to divide 66418860 by 98.

Going ahead to step 1:
If we divide 6 by 98, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 98

Going ahead to step 2:
The number 98 fits into 66 0 times, leaving a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Fetch the next digit (4) from the dividend, attach it to 66 and continue: 664 / 98

On to step 3:
If we divide 664 by 98, we get 6 and a remainder of 76.
The next digit of our result is 6. 
Result so far: 6.0
If we take 588 away from 664, we end up with 76.
Grab the next digit (1) from the dividend, add it to 76, then carry on: 761 / 98

Going ahead to step 4:
761 divided by 98 is 7 with a remainder of 75.
Put 7 as the next digit of the answer. 
Result so far: 67.0
Deduct 686 from 761 and we're left with 75.
Take the next digit (8) from the dividend and append it to 75, then repeat: 758 / 98

On to step 5:
98 goes into 758 7 times with a remainder of 72.
Record the quotient 7 as the next digit in the result. 
Result so far: 677.0
Subtracting 686 from 758 leaves us with 72.
Fetch the next digit (8) from the dividend, attach it to 72 and continue: 728 / 98

Moving on to step 6:
The number 98 fits into 728 7 times, leaving a remainder of 42.
Write down 7 as next digit of the result. 
Result so far: 6777.0
Deduct 686 from 728 and we're left with 42.
Take the next digit (6) from the dividend and append it to 42, then repeat: 426 / 98

Going ahead to step 7:
98 goes into 426 4 times with a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 67774.0
Subtract 392 from 426 to get 34.
Take the next digit (0) from the dividend and append it to 34, then repeat: 340 / 98

Advancing to step 8:
98 goes into 340 3 times with a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 677743.0
Subtract 294 from 340 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 9:
98 goes into 460 4 times with a remainder of 68.
The next digit of our result is 4. 
Result so far: 677743.4
Subtract 392 from 460 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 10:
98 can be fit into 680 6 times, resulting in a remainder of 92.
Record the quotient 6 as the next digit in the result. 
Result so far: 677743.46
Subtract 588 from 680 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 11:
When dividing 920 by 98, we get 9 with a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 677743.469
Subtract 882 from 920 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 12:
If we divide 380 by 98, we get 3 and a remainder of 86.
Write down 3 as next digit of the result. 
Result so far: 677743.4693
Subtracting 294 from 380 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 13:
The number 98 fits into 860 8 times, leaving a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 677743.46938
If we take 784 away from 860, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 14:
98 can be fit into 760 7 times, resulting in a remainder of 74.
The number 7 becomes the next digit in our result. 
Result so far: 677743.469387
If we subtract 686 from 760, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 15:
98 can be fit into 740 7 times, resulting in a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 677743.4693877
Deduct 686 from 740 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final outcome is 677743.4693877, with a leftover of 5.4e-07.
