We look at the division of 98515831 by 631 
Our goal is to divide 98515831 by 631.

Moving on to step 1:
If we divide 9 by 631, we get 0 and 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.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 631

Moving on to step 2:
When dividing 98 by 631, we get 0 with 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 (5) of the dividend behind the 98 and repeat the process: 985 / 631

Let's proceed to step 3:
If we divide 985 by 631, we get 1 and a remainder of 354.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 631 from 985 and we're left with 354.
Fetch the next digit (1) from the dividend, attach it to 354 and continue: 3541 / 631

Moving on to step 4:
3541 divided by 631 is 5 with a remainder of 386.
The next digit of our result is 5. 
Result so far: 15.0
Subtract 3155 from 3541 to get 386.
Fetch the next digit (5) from the dividend, attach it to 386 and continue: 3865 / 631

Going ahead to step 5:
When dividing 3865 by 631, we get 6 with a remainder of 79.
Record the quotient 6 as the next digit in the result. 
Result so far: 156.0
If we subtract 3786 from 3865, we get 79.
Grab the next digit (8) from the dividend, add it to 79, then carry on: 798 / 631

On to step 6:
When dividing 798 by 631, we get 1 with a remainder of 167.
The number 1 becomes the next digit in our result. 
Result so far: 1561.0
Deduct 631 from 798 and we're left with 167.
Grab the next digit (3) from the dividend, add it to 167, then carry on: 1673 / 631

Let's proceed to step 7:
If we divide 1673 by 631, we get 2 and a remainder of 411.
The next digit of our result is 2. 
Result so far: 15612.0
Deduct 1262 from 1673 and we're left with 411.
Include the next digit (1) from the dividend after 411, then repeat: 4111 / 631

Advancing to step 8:
631 can be fit into 4111 6 times, resulting in a remainder of 325.
The next digit of our result is 6. 
Result so far: 156126.0
The remainder is 325 after subtracting 3786 from 4111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Moving on to step 9:
The number 631 fits into 3250 5 times, leaving a remainder of 95.
Use 5 as the next digit of our solution. 
Result so far: 156126.5
Subtracting 3155 from 3250 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Let's proceed to step 10:
When dividing 950 by 631, we get 1 with a remainder of 319.
Put 1 as the next digit of the answer. 
Result so far: 156126.51
If we subtract 631 from 950, we get 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Advancing to step 11:
The number 631 fits into 3190 5 times, leaving a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 156126.515
Subtract 3155 from 3190 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 12:
631 goes into 350 0 times with a remainder of 350.
Use 0 as the next digit of our solution. 
Result so far: 156126.515
The remainder is 350 after subtracting 0 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Moving on to step 13:
The number 631 fits into 3500 5 times, leaving a remainder of 345.
Put 5 as the next digit of the answer. 
Result so far: 156126.51505
If we subtract 3155 from 3500, we get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Step 14:
631 goes into 3450 5 times with a remainder of 295.
Write down 5 as next digit of the result. 
Result so far: 156126.515055
Subtract 3155 from 3450 to get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

The quotient of the division is 156126.515055, and the remainder is 2.95e-05.
