Let's divide 50638121 by 670
Our goal is to divide 50638121 by 670.

On to step 1:
If we divide 5 by 670, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 670

Step 2:
50 divided by 670 is 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 50 leaves us with 50.
Bring next digit (6) of the dividend behind the 50 and repeat the process: 506 / 670

On to step 3:
670 can be fit into 506 0 times, resulting in a remainder of 506.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 506, we get 506.
Grab the next digit (3) from the dividend, add it to 506, then carry on: 5063 / 670

Step 4:
When dividing 5063 by 670, we get 7 with a remainder of 373.
The next digit of our result is 7. 
Result so far: 7.0
If we take 4690 away from 5063, we end up with 373.
Include the next digit (8) from the dividend after 373, then repeat: 3738 / 670

Going ahead to step 5:
The number 670 fits into 3738 5 times, leaving a remainder of 388.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
If we subtract 3350 from 3738, we get 388.
Fetch the next digit (1) from the dividend, attach it to 388 and continue: 3881 / 670

Advancing to step 6:
When dividing 3881 by 670, we get 5 with a remainder of 531.
The number 5 becomes the next digit in our result. 
Result so far: 755.0
If we subtract 3350 from 3881, we get 531.
Include the next digit (2) from the dividend after 531, then repeat: 5312 / 670

Step 7:
5312 divided by 670 is 7 with a remainder of 622.
Use 7 as the next digit of our solution. 
Result so far: 7557.0
If we subtract 4690 from 5312, we get 622.
Grab the next digit (1) from the dividend, add it to 622, then carry on: 6221 / 670

Step 8:
The number 670 fits into 6221 9 times, leaving a remainder of 191.
Use 9 as the next digit of our solution. 
Result so far: 75579.0
Subtract 6030 from 6221 to get 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Advancing to step 9:
If we divide 1910 by 670, we get 2 and a remainder of 570.
The number 2 becomes the next digit in our result. 
Result so far: 75579.2
The remainder is 570 after subtracting 1340 from 1910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Let's proceed to step 10:
When dividing 5700 by 670, we get 8 with a remainder of 340.
Write down 8 as next digit of the result. 
Result so far: 75579.28
Deduct 5360 from 5700 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 11:
670 can be fit into 3400 5 times, resulting in a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 75579.285
Subtract 3350 from 3400 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 12:
When dividing 500 by 670, we get 0 with a remainder of 500.
Use 0 as the next digit of our solution. 
Result so far: 75579.285
Deduct 0 from 500 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Moving on to step 13:
When dividing 5000 by 670, we get 7 with a remainder of 310.
Write down 7 as next digit of the result. 
Result so far: 75579.28507
If we take 4690 away from 5000, we end up with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 14:
3100 divided by 670 is 4 with a remainder of 420.
The number 4 becomes the next digit in our result. 
Result so far: 75579.285074
If we subtract 2680 from 3100, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 15:
670 goes into 4200 6 times with a remainder of 180.
The next digit of our result is 6. 
Result so far: 75579.2850746
If we subtract 4020 from 4200, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 16:
670 can be fit into 1800 2 times, resulting in a remainder of 460.
Put 2 as the next digit of the answer. 
Result so far: 75579.28507462
If we take 1340 away from 1800, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

After the division, we end up with 75579.28507462 and a remainder of 4.6e-07.
