30163979 ÷ 637 
Our goal is to divide 30163979 by 637.

Step 1:
If we divide 3 by 637, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 637

On to step 2:
If we divide 30 by 637, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Grab the next digit (1) from the dividend, add it to 30, then carry on: 301 / 637

Going ahead to step 3:
The number 637 fits into 301 0 times, leaving a remainder of 301.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 301 to get 301.
Include the next digit (6) from the dividend after 301, then repeat: 3016 / 637

Going ahead to step 4:
637 can be fit into 3016 4 times, resulting in a remainder of 468.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 2548 away from 3016, we end up with 468.
Take the next digit (3) from the dividend and append it to 468, then repeat: 4683 / 637

Let's proceed to step 5:
4683 divided by 637 is 7 with a remainder of 224.
Put 7 as the next digit of the answer. 
Result so far: 47.0
Subtracting 4459 from 4683 leaves us with 224.
Fetch the next digit (9) from the dividend, attach it to 224 and continue: 2249 / 637

Advancing to step 6:
637 goes into 2249 3 times with a remainder of 338.
Use 3 as the next digit of our solution. 
Result so far: 473.0
If we take 1911 away from 2249, we end up with 338.
Fetch the next digit (7) from the dividend, attach it to 338 and continue: 3387 / 637

Step 7:
When dividing 3387 by 637, we get 5 with a remainder of 202.
Record the quotient 5 as the next digit in the result. 
Result so far: 4735.0
If we take 3185 away from 3387, we end up with 202.
Bring next digit (9) of the dividend behind the 202 and repeat the process: 2029 / 637

Advancing to step 8:
The number 637 fits into 2029 3 times, leaving a remainder of 118.
Put 3 as the next digit of the answer. 
Result so far: 47353.0
If we subtract 1911 from 2029, we get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Advancing to step 9:
If we divide 1180 by 637, we get 1 and a remainder of 543.
Use 1 as the next digit of our solution. 
Result so far: 47353.1
The remainder is 543 after subtracting 637 from 1180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5430, and continue the process.

Advancing to step 10:
When dividing 5430 by 637, we get 8 with a remainder of 334.
Use 8 as the next digit of our solution. 
Result so far: 47353.18
Subtracting 5096 from 5430 leaves us with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Moving on to step 11:
When dividing 3340 by 637, we get 5 with a remainder of 155.
Write down 5 as next digit of the result. 
Result so far: 47353.185
Subtracting 3185 from 3340 leaves us with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Advancing to step 12:
When dividing 1550 by 637, we get 2 with a remainder of 276.
Put 2 as the next digit of the answer. 
Result so far: 47353.1852
The remainder is 276 after subtracting 1274 from 1550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Moving on to step 13:
637 goes into 2760 4 times with a remainder of 212.
The next digit of our result is 4. 
Result so far: 47353.18524
If we take 2548 away from 2760, we end up with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Let's proceed to step 14:
637 can be fit into 2120 3 times, resulting in a remainder of 209.
Record the quotient 3 as the next digit in the result. 
Result so far: 47353.185243
Deduct 1911 from 2120 and we're left with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Moving on to step 15:
The number 637 fits into 2090 3 times, leaving a remainder of 179.
Use 3 as the next digit of our solution. 
Result so far: 47353.1852433
The remainder is 179 after subtracting 1911 from 2090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

After the division, we end up with 47353.1852433 and a remainder of 1.79e-06.
