30445451 ÷ 631 
We want to divide 30445451 by 631.

Moving on to step 1:
631 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 631

Moving on to step 2:
631 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Take the next digit (4) from the dividend and append it to 30, then repeat: 304 / 631

Going ahead to step 3:
The number 631 fits into 304 0 times, leaving a remainder of 304.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 304, we end up with 304.
Take the next digit (4) from the dividend and append it to 304, then repeat: 3044 / 631

Advancing to step 4:
The number 631 fits into 3044 4 times, leaving a remainder of 520.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 2524 away from 3044, we end up with 520.
Grab the next digit (5) from the dividend, add it to 520, then carry on: 5205 / 631

Moving on to step 5:
If we divide 5205 by 631, we get 8 and a remainder of 157.
The next digit of our result is 8. 
Result so far: 48.0
If we take 5048 away from 5205, we end up with 157.
Fetch the next digit (4) from the dividend, attach it to 157 and continue: 1574 / 631

Let's proceed to step 6:
631 can be fit into 1574 2 times, resulting in a remainder of 312.
The next digit of our result is 2. 
Result so far: 482.0
If we subtract 1262 from 1574, we get 312.
Include the next digit (5) from the dividend after 312, then repeat: 3125 / 631

Moving on to step 7:
When dividing 3125 by 631, we get 4 with a remainder of 601.
The next digit of our result is 4. 
Result so far: 4824.0
Subtracting 2524 from 3125 leaves us with 601.
Include the next digit (1) from the dividend after 601, then repeat: 6011 / 631

Let's proceed to step 8:
When dividing 6011 by 631, we get 9 with a remainder of 332.
Record the quotient 9 as the next digit in the result. 
Result so far: 48249.0
If we subtract 5679 from 6011, we get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Step 9:
631 goes into 3320 5 times with a remainder of 165.
Put 5 as the next digit of the answer. 
Result so far: 48249.5
If we subtract 3155 from 3320, we get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Step 10:
When dividing 1650 by 631, we get 2 with a remainder of 388.
Record the quotient 2 as the next digit in the result. 
Result so far: 48249.52
Subtracting 1262 from 1650 leaves us with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

On to step 11:
The number 631 fits into 3880 6 times, leaving a remainder of 94.
Write down 6 as next digit of the result. 
Result so far: 48249.526
If we take 3786 away from 3880, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 12:
The number 631 fits into 940 1 times, leaving a remainder of 309.
Record the quotient 1 as the next digit in the result. 
Result so far: 48249.5261
Subtracting 631 from 940 leaves us with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Going ahead to step 13:
631 can be fit into 3090 4 times, resulting in a remainder of 566.
The next digit of our result is 4. 
Result so far: 48249.52614
If we take 2524 away from 3090, we end up with 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

Moving on to step 14:
If we divide 5660 by 631, we get 8 and a remainder of 612.
Use 8 as the next digit of our solution. 
Result so far: 48249.526148
Subtract 5048 from 5660 to get 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Step 15:
If we divide 6120 by 631, we get 9 and a remainder of 441.
Record the quotient 9 as the next digit in the result. 
Result so far: 48249.5261489
The remainder is 441 after subtracting 5679 from 6120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

Advancing to step 16:
If we divide 4410 by 631, we get 6 and a remainder of 624.
Write down 6 as next digit of the result. 
Result so far: 48249.52614896
Deduct 3786 from 4410 and we're left with 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

The quotient of the division is 48249.52614896, and the remainder is 6.24e-07.
