We're dividing 12137058 by 455 
We want to figure out the number of times 12137058 can be divided by 455.

Going ahead to step 1:
The number 455 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 455

Step 2:
455 goes into 12 0 times with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 455

On to step 3:
The number 455 fits into 121 0 times, leaving a remainder of 121.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 121 and we're left with 121.
Fetch the next digit (3) from the dividend, attach it to 121 and continue: 1213 / 455

Step 4:
1213 divided by 455 is 2 with a remainder of 303.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 910 from 1213, we get 303.
Grab the next digit (7) from the dividend, add it to 303, then carry on: 3037 / 455

On to step 5:
455 can be fit into 3037 6 times, resulting in a remainder of 307.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Deduct 2730 from 3037 and we're left with 307.
Grab the next digit (0) from the dividend, add it to 307, then carry on: 3070 / 455

Let's proceed to step 6:
The number 455 fits into 3070 6 times, leaving a remainder of 340.
Write down 6 as next digit of the result. 
Result so far: 266.0
Subtracting 2730 from 3070 leaves us with 340.
Fetch the next digit (5) from the dividend, attach it to 340 and continue: 3405 / 455

Going ahead to step 7:
455 goes into 3405 7 times with a remainder of 220.
Put 7 as the next digit of the answer. 
Result so far: 2667.0
If we subtract 3185 from 3405, we get 220.
Take the next digit (8) from the dividend and append it to 220, then repeat: 2208 / 455

Step 8:
If we divide 2208 by 455, we get 4 and a remainder of 388.
Write down 4 as next digit of the result. 
Result so far: 26674.0
The remainder is 388 after subtracting 1820 from 2208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Going ahead to step 9:
If we divide 3880 by 455, we get 8 and a remainder of 240.
Use 8 as the next digit of our solution. 
Result so far: 26674.8
If we take 3640 away from 3880, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 10:
If we divide 2400 by 455, we get 5 and a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 26674.85
Subtract 2275 from 2400 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 11:
When dividing 1250 by 455, we get 2 with a remainder of 340.
Record the quotient 2 as the next digit in the result. 
Result so far: 26674.852
Subtract 910 from 1250 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 12:
The number 455 fits into 3400 7 times, leaving a remainder of 215.
The next digit of our result is 7. 
Result so far: 26674.8527
Subtract 3185 from 3400 to get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

On to step 13:
2150 divided by 455 is 4 with a remainder of 330.
Write down 4 as next digit of the result. 
Result so far: 26674.85274
Subtracting 1820 from 2150 leaves us with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Advancing to step 14:
455 can be fit into 3300 7 times, resulting in a remainder of 115.
Put 7 as the next digit of the answer. 
Result so far: 26674.852747
Subtract 3185 from 3300 to get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Advancing to step 15:
1150 divided by 455 is 2 with a remainder of 240.
Use 2 as the next digit of our solution. 
Result so far: 26674.8527472
Deduct 910 from 1150 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 16:
455 can be fit into 2400 5 times, resulting in a remainder of 125.
Use 5 as the next digit of our solution. 
Result so far: 26674.85274725
Deduct 2275 from 2400 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

The final result is 26674.85274725 with a remainder of 1.25e-07.
