We look at the division of 49018991 by 126 
We want to divide 49018991 by 126.

Moving on to step 1:
If we divide 4 by 126, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 126

On to step 2:
49 divided by 126 is 0 with a remainder of 49.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 49, we get 49.
Bring next digit (0) of the dividend behind the 49 and repeat the process: 490 / 126

Advancing to step 3:
126 can be fit into 490 3 times, resulting in a remainder of 112.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 378 away from 490, we end up with 112.
Grab the next digit (1) from the dividend, add it to 112, then carry on: 1121 / 126

Going ahead to step 4:
1121 divided by 126 is 8 with a remainder of 113.
Put 8 as the next digit of the answer. 
Result so far: 38.0
If we subtract 1008 from 1121, we get 113.
Fetch the next digit (8) from the dividend, attach it to 113 and continue: 1138 / 126

Moving on to step 5:
The number 126 fits into 1138 9 times, leaving a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 389.0
If we subtract 1134 from 1138, we get 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 126

Step 6:
49 divided by 126 is 0 with a remainder of 49.
The next digit of our result is 0. 
Result so far: 3890.0
If we subtract 0 from 49, we get 49.
Append the next digit (9) from the dividend to 49 and continue with: 499 / 126

Step 7:
126 can be fit into 499 3 times, resulting in a remainder of 121.
Use 3 as the next digit of our solution. 
Result so far: 38903.0
If we take 378 away from 499, we end up with 121.
Bring next digit (1) of the dividend behind the 121 and repeat the process: 1211 / 126

Step 8:
When dividing 1211 by 126, we get 9 with a remainder of 77.
The number 9 becomes the next digit in our result. 
Result so far: 389039.0
Subtract 1134 from 1211 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 9:
126 goes into 770 6 times with a remainder of 14.
The next digit of our result is 6. 
Result so far: 389039.6
If we subtract 756 from 770, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 10:
126 can be fit into 140 1 times, resulting in a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 389039.61
Deduct 126 from 140 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 11:
If we divide 140 by 126, we get 1 and a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 389039.611
Deduct 126 from 140 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 389039.611 and a remainder of 0.0014.
