Let's divide 45712426 by 521
Let's see how many times 521 fits into 45712426.

Going ahead to step 1:
If we divide 4 by 521, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 521

Moving on to step 2:
45 divided by 521 is 0 with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Grab the next digit (7) from the dividend, add it to 45, then carry on: 457 / 521

Let's proceed to step 3:
If we divide 457 by 521, we get 0 and a remainder of 457.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 457 to get 457.
Append the next digit (1) from the dividend to 457 and continue with: 4571 / 521

Step 4:
521 goes into 4571 8 times with a remainder of 403.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 4168 from 4571 and we're left with 403.
Append the next digit (2) from the dividend to 403 and continue with: 4032 / 521

Let's proceed to step 5:
When dividing 4032 by 521, we get 7 with a remainder of 385.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
If we take 3647 away from 4032, we end up with 385.
Append the next digit (4) from the dividend to 385 and continue with: 3854 / 521

Advancing to step 6:
If we divide 3854 by 521, we get 7 and a remainder of 207.
Put 7 as the next digit of the answer. 
Result so far: 877.0
Subtract 3647 from 3854 to get 207.
Fetch the next digit (2) from the dividend, attach it to 207 and continue: 2072 / 521

Advancing to step 7:
When dividing 2072 by 521, we get 3 with a remainder of 509.
Record the quotient 3 as the next digit in the result. 
Result so far: 8773.0
The remainder is 509 after subtracting 1563 from 2072.
Bring next digit (6) of the dividend behind the 509 and repeat the process: 5096 / 521

Moving on to step 8:
When dividing 5096 by 521, we get 9 with a remainder of 407.
Write down 9 as next digit of the result. 
Result so far: 87739.0
Subtract 4689 from 5096 to get 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Moving on to step 9:
521 goes into 4070 7 times with a remainder of 423.
The next digit of our result is 7. 
Result so far: 87739.7
Subtracting 3647 from 4070 leaves us with 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Advancing to step 10:
When dividing 4230 by 521, we get 8 with a remainder of 62.
The next digit of our result is 8. 
Result so far: 87739.78
Deduct 4168 from 4230 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 11:
When dividing 620 by 521, we get 1 with a remainder of 99.
The number 1 becomes the next digit in our result. 
Result so far: 87739.781
The remainder is 99 after subtracting 521 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Let's proceed to step 12:
521 can be fit into 990 1 times, resulting in a remainder of 469.
Put 1 as the next digit of the answer. 
Result so far: 87739.7811
Subtract 521 from 990 to get 469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

After the division, we end up with 87739.7811 and a remainder of 0.00469.
