We're dividing 12119540 by 458 
We're looking to find how many times 458 goes into 12119540.

Moving on to step 1:
If we divide 1 by 458, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 458

Going ahead to step 2:
When dividing 12 by 458, we get 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 458

Going ahead to step 3:
When dividing 121 by 458, we get 0 with a remainder of 121.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 121, we get 121.
Fetch the next digit (1) from the dividend, attach it to 121 and continue: 1211 / 458

Going ahead to step 4:
If we divide 1211 by 458, we get 2 and a remainder of 295.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 916 from 1211 to get 295.
Grab the next digit (9) from the dividend, add it to 295, then carry on: 2959 / 458

Step 5:
If we divide 2959 by 458, we get 6 and a remainder of 211.
Use 6 as the next digit of our solution. 
Result so far: 26.0
If we take 2748 away from 2959, we end up with 211.
Bring next digit (5) of the dividend behind the 211 and repeat the process: 2115 / 458

Step 6:
When dividing 2115 by 458, we get 4 with a remainder of 283.
Use 4 as the next digit of our solution. 
Result so far: 264.0
Subtracting 1832 from 2115 leaves us with 283.
Include the next digit (4) from the dividend after 283, then repeat: 2834 / 458

Advancing to step 7:
458 goes into 2834 6 times with a remainder of 86.
Put 6 as the next digit of the answer. 
Result so far: 2646.0
If we subtract 2748 from 2834, we get 86.
Bring next digit (0) of the dividend behind the 86 and repeat the process: 860 / 458

On to step 8:
458 can be fit into 860 1 times, resulting in a remainder of 402.
The next digit of our result is 1. 
Result so far: 26461.0
Subtract 458 from 860 to get 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

On to step 9:
458 can be fit into 4020 8 times, resulting in a remainder of 356.
Write down 8 as next digit of the result. 
Result so far: 26461.8
Subtracting 3664 from 4020 leaves us with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

On to step 10:
When dividing 3560 by 458, we get 7 with a remainder of 354.
The next digit of our result is 7. 
Result so far: 26461.87
Deduct 3206 from 3560 and we're left with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Moving on to step 11:
The number 458 fits into 3540 7 times, leaving a remainder of 334.
Write down 7 as next digit of the result. 
Result so far: 26461.877
Deduct 3206 from 3540 and we're left 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.

After the division, we end up with 26461.877 and a remainder of 0.0334.
