We're dividing 9970482 by 631 
We want to divide 9970482 by 631.

Step 1:
The number 631 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 631

Step 2:
If we divide 99 by 631, we get 0 and a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 99 to get 99.
Grab the next digit (7) from the dividend, add it to 99, then carry on: 997 / 631

Let's proceed to step 3:
997 divided by 631 is 1 with a remainder of 366.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 631 from 997 to get 366.
Grab the next digit (0) from the dividend, add it to 366, then carry on: 3660 / 631

On to step 4:
The number 631 fits into 3660 5 times, leaving a remainder of 505.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Deduct 3155 from 3660 and we're left with 505.
Take the next digit (4) from the dividend and append it to 505, then repeat: 5054 / 631

Going ahead to step 5:
631 goes into 5054 8 times with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 158.0
Deduct 5048 from 5054 and we're left with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 631

Moving on to step 6:
The number 631 fits into 68 0 times, leaving a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 1580.0
Subtract 0 from 68 to get 68.
Grab the next digit (2) from the dividend, add it to 68, then carry on: 682 / 631

On to step 7:
When dividing 682 by 631, we get 1 with a remainder of 51.
The number 1 becomes the next digit in our result. 
Result so far: 15801.0
Deduct 631 from 682 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 8:
When dividing 510 by 631, we get 0 with a remainder of 510.
Put 0 as the next digit of the answer. 
Result so far: 15801.0
If we subtract 0 from 510, we get 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Going ahead to step 9:
631 goes into 5100 8 times with a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 15801.08
If we subtract 5048 from 5100, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 10:
When dividing 520 by 631, we get 0 with a remainder of 520.
Use 0 as the next digit of our solution. 
Result so far: 15801.08
Subtracting 0 from 520 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Going ahead to step 11:
631 goes into 5200 8 times with a remainder of 152.
Put 8 as the next digit of the answer. 
Result so far: 15801.0808
Subtracting 5048 from 5200 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Let's proceed to step 12:
631 goes into 1520 2 times with a remainder of 258.
Put 2 as the next digit of the answer. 
Result so far: 15801.08082
Subtract 1262 from 1520 to get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Advancing to step 13:
2580 divided by 631 is 4 with a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 15801.080824
The remainder is 56 after subtracting 2524 from 2580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 14:
560 divided by 631 is 0 with a remainder of 560.
The number 0 becomes the next digit in our result. 
Result so far: 15801.080824
Subtract 0 from 560 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 15:
If we divide 5600 by 631, we get 8 and a remainder of 552.
Write down 8 as next digit of the result. 
Result so far: 15801.08082408
Subtract 5048 from 5600 to get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

After the division, we end up with 15801.08082408 and a remainder of 5.52e-07.
