98198410 ÷ 166 
We want to divide 98198410 by 166.

Moving on to step 1:
The number 166 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 166

Going ahead to step 2:
166 can be fit into 98 0 times, resulting in a remainder of 98.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 98 to get 98.
Bring next digit (1) of the dividend behind the 98 and repeat the process: 981 / 166

On to step 3:
When dividing 981 by 166, we get 5 with a remainder of 151.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 830 from 981, we get 151.
Grab the next digit (9) from the dividend, add it to 151, then carry on: 1519 / 166

Advancing to step 4:
166 goes into 1519 9 times with a remainder of 25.
Record the quotient 9 as the next digit in the result. 
Result so far: 59.0
The remainder is 25 after subtracting 1494 from 1519.
Include the next digit (8) from the dividend after 25, then repeat: 258 / 166

On to step 5:
166 can be fit into 258 1 times, resulting in a remainder of 92.
Record the quotient 1 as the next digit in the result. 
Result so far: 591.0
The remainder is 92 after subtracting 166 from 258.
Fetch the next digit (4) from the dividend, attach it to 92 and continue: 924 / 166

Going ahead to step 6:
If we divide 924 by 166, we get 5 and a remainder of 94.
The number 5 becomes the next digit in our result. 
Result so far: 5915.0
The remainder is 94 after subtracting 830 from 924.
Append the next digit (1) from the dividend to 94 and continue with: 941 / 166

Let's proceed to step 7:
166 can be fit into 941 5 times, resulting in a remainder of 111.
The next digit of our result is 5. 
Result so far: 59155.0
The remainder is 111 after subtracting 830 from 941.
Bring next digit (0) of the dividend behind the 111 and repeat the process: 1110 / 166

Let's proceed to step 8:
1110 divided by 166 is 6 with a remainder of 114.
Use 6 as the next digit of our solution. 
Result so far: 591556.0
The remainder is 114 after subtracting 996 from 1110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Step 9:
166 can be fit into 1140 6 times, resulting in a remainder of 144.
Use 6 as the next digit of our solution. 
Result so far: 591556.6
If we take 996 away from 1140, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 10:
When dividing 1440 by 166, we get 8 with a remainder of 112.
Write down 8 as next digit of the result. 
Result so far: 591556.68
Subtracting 1328 from 1440 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 11:
The number 166 fits into 1120 6 times, leaving a remainder of 124.
Record the quotient 6 as the next digit in the result. 
Result so far: 591556.686
Deduct 996 from 1120 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Step 12:
166 goes into 1240 7 times with a remainder of 78.
The next digit of our result is 7. 
Result so far: 591556.6867
If we subtract 1162 from 1240, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 13:
780 divided by 166 is 4 with a remainder of 116.
Record the quotient 4 as the next digit in the result. 
Result so far: 591556.68674
Deduct 664 from 780 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Let's proceed to step 14:
The number 166 fits into 1160 6 times, leaving a remainder of 164.
The number 6 becomes the next digit in our result. 
Result so far: 591556.686746
Subtract 996 from 1160 to get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Advancing to step 15:
If we divide 1640 by 166, we get 9 and a remainder of 146.
Write down 9 as next digit of the result. 
Result so far: 591556.6867469
The remainder is 146 after subtracting 1494 from 1640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

On to step 16:
1460 divided by 166 is 8 with a remainder of 132.
The number 8 becomes the next digit in our result. 
Result so far: 591556.68674698
Subtract 1328 from 1460 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

In conclusion, the division gives 591556.68674698 with a balance of 1.32e-07.
