98388158 ÷ 210 
Our goal is to divide 98388158 by 210.

Moving on to step 1:
210 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 210

Step 2:
The number 210 fits into 98 0 times, leaving a remainder of 98.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 98 after subtracting 0 from 98.
Bring next digit (3) of the dividend behind the 98 and repeat the process: 983 / 210

Moving on to step 3:
210 goes into 983 4 times with a remainder of 143.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 840 from 983 leaves us with 143.
Take the next digit (8) from the dividend and append it to 143, then repeat: 1438 / 210

Going ahead to step 4:
210 goes into 1438 6 times with a remainder of 178.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
Subtracting 1260 from 1438 leaves us with 178.
Grab the next digit (8) from the dividend, add it to 178, then carry on: 1788 / 210

Let's proceed to step 5:
210 can be fit into 1788 8 times, resulting in a remainder of 108.
Record the quotient 8 as the next digit in the result. 
Result so far: 468.0
Subtracting 1680 from 1788 leaves us with 108.
Fetch the next digit (1) from the dividend, attach it to 108 and continue: 1081 / 210

Advancing to step 6:
1081 divided by 210 is 5 with a remainder of 31.
Use 5 as the next digit of our solution. 
Result so far: 4685.0
The remainder is 31 after subtracting 1050 from 1081.
Append the next digit (5) from the dividend to 31 and continue with: 315 / 210

Let's proceed to step 7:
When dividing 315 by 210, we get 1 with a remainder of 105.
Put 1 as the next digit of the answer. 
Result so far: 46851.0
Deduct 210 from 315 and we're left with 105.
Fetch the next digit (8) from the dividend, attach it to 105 and continue: 1058 / 210

Going ahead to step 8:
210 goes into 1058 5 times with a remainder of 8.
Write down 5 as next digit of the result. 
Result so far: 468515.0
Subtracting 1050 from 1058 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
80 divided by 210 is 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 468515.0
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 10:
800 divided by 210 is 3 with a remainder of 170.
Record the quotient 3 as the next digit in the result. 
Result so far: 468515.03
Subtracting 630 from 800 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 11:
210 can be fit into 1700 8 times, resulting in a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 468515.038
Deduct 1680 from 1700 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 12:
210 goes into 200 0 times with a remainder of 200.
The next digit of our result is 0. 
Result so far: 468515.038
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 13:
When dividing 2000 by 210, we get 9 with a remainder of 110.
The next digit of our result is 9. 
Result so far: 468515.03809
Subtracting 1890 from 2000 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 14:
210 can be fit into 1100 5 times, resulting in a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 468515.038095
Subtracting 1050 from 1100 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 15:
When dividing 500 by 210, we get 2 with a remainder of 80.
The number 2 becomes the next digit in our result. 
Result so far: 468515.0380952
Subtracting 420 from 500 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 16:
210 can be fit into 800 3 times, resulting in a remainder of 170.
Record the quotient 3 as the next digit in the result. 
Result so far: 468515.03809523
If we subtract 630 from 800, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

The final outcome is 468515.03809523, with a leftover of 1.7e-07.
