We're dividing 5106521 by 445 
We want to figure out the number of times 5106521 can be divided by 445.

Going ahead to step 1:
The number 445 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 445

Step 2:
445 can be fit into 51 0 times, resulting in a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Bring next digit (0) of the dividend behind the 51 and repeat the process: 510 / 445

Moving on to step 3:
When dividing 510 by 445, we get 1 with a remainder of 65.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 445 from 510 and we're left with 65.
Include the next digit (6) from the dividend after 65, then repeat: 656 / 445

On to step 4:
If we divide 656 by 445, we get 1 and a remainder of 211.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we subtract 445 from 656, we get 211.
Fetch the next digit (5) from the dividend, attach it to 211 and continue: 2115 / 445

Step 5:
The number 445 fits into 2115 4 times, leaving a remainder of 335.
Use 4 as the next digit of our solution. 
Result so far: 114.0
Subtract 1780 from 2115 to get 335.
Bring next digit (2) of the dividend behind the 335 and repeat the process: 3352 / 445

Step 6:
When dividing 3352 by 445, we get 7 with a remainder of 237.
Record the quotient 7 as the next digit in the result. 
Result so far: 1147.0
If we subtract 3115 from 3352, we get 237.
Include the next digit (1) from the dividend after 237, then repeat: 2371 / 445

Step 7:
When dividing 2371 by 445, we get 5 with a remainder of 146.
The next digit of our result is 5. 
Result so far: 11475.0
If we take 2225 away from 2371, we end up with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Moving on to step 8:
445 goes into 1460 3 times with a remainder of 125.
Put 3 as the next digit of the answer. 
Result so far: 11475.3
If we take 1335 away from 1460, we end up 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.

Advancing to step 9:
The number 445 fits into 1250 2 times, leaving a remainder of 360.
Write down 2 as next digit of the result. 
Result so far: 11475.32
Deduct 890 from 1250 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 10:
If we divide 3600 by 445, we get 8 and a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 11475.328
Deduct 3560 from 3600 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
445 goes into 400 0 times with a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 11475.328
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 12:
The number 445 fits into 4000 8 times, leaving a remainder of 440.
The next digit of our result is 8. 
Result so far: 11475.32808
Subtract 3560 from 4000 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 13:
445 goes into 4400 9 times with a remainder of 395.
Use 9 as the next digit of our solution. 
Result so far: 11475.328089
The remainder is 395 after subtracting 4005 from 4400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Moving on to step 14:
The number 445 fits into 3950 8 times, leaving a remainder of 390.
Record the quotient 8 as the next digit in the result. 
Result so far: 11475.3280898
Subtracting 3560 from 3950 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Going ahead to step 15:
445 goes into 3900 8 times with a remainder of 340.
Write down 8 as next digit of the result. 
Result so far: 11475.32808988
The remainder is 340 after subtracting 3560 from 3900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

The final result is 11475.32808988 with a remainder of 3.4e-07.
