We divide 15670680 by 521
We want to figure out the number of times 15670680 can be divided by 521.

Step 1:
If we divide 1 by 521, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 521

Going ahead to step 2:
15 divided by 521 is 0 with a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Take the next digit (6) from the dividend and append it to 15, then repeat: 156 / 521

Going ahead to step 3:
When dividing 156 by 521, we get 0 with a remainder of 156.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 156 after subtracting 0 from 156.
Append the next digit (7) from the dividend to 156 and continue with: 1567 / 521

On to step 4:
When dividing 1567 by 521, we get 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 1563 away from 1567, we end up with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 521

Let's proceed to step 5:
521 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
The remainder is 40 after subtracting 0 from 40.
Bring next digit (6) of the dividend behind the 40 and repeat the process: 406 / 521

Going ahead to step 6:
406 divided by 521 is 0 with a remainder of 406.
Put 0 as the next digit of the answer. 
Result so far: 300.0
Deduct 0 from 406 and we're left with 406.
Grab the next digit (8) from the dividend, add it to 406, then carry on: 4068 / 521

Step 7:
If we divide 4068 by 521, we get 7 and a remainder of 421.
Put 7 as the next digit of the answer. 
Result so far: 3007.0
The remainder is 421 after subtracting 3647 from 4068.
Bring next digit (0) of the dividend behind the 421 and repeat the process: 4210 / 521

Let's proceed to step 8:
521 goes into 4210 8 times with a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 30078.0
If we take 4168 away from 4210, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 9:
If we divide 420 by 521, we get 0 and a remainder of 420.
Write down 0 as next digit of the result. 
Result so far: 30078.0
Subtracting 0 from 420 leaves us with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Advancing to step 10:
4200 divided by 521 is 8 with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 30078.08
Subtract 4168 from 4200 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 11:
521 goes into 320 0 times with a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 30078.08
Subtract 0 from 320 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 12:
3200 divided by 521 is 6 with a remainder of 74.
The number 6 becomes the next digit in our result. 
Result so far: 30078.0806
The remainder is 74 after subtracting 3126 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 13:
740 divided by 521 is 1 with a remainder of 219.
Use 1 as the next digit of our solution. 
Result so far: 30078.08061
If we take 521 away from 740, we end up with 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Moving on to step 14:
When dividing 2190 by 521, we get 4 with a remainder of 106.
Write down 4 as next digit of the result. 
Result so far: 30078.080614
Deduct 2084 from 2190 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 15:
521 goes into 1060 2 times with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 30078.0806142
If we take 1042 away from 1060, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 16:
If we divide 180 by 521, we get 0 and a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 30078.0806142
If we take 0 away from 180, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

After the division, we end up with 30078.0806142 and a remainder of 1.8e-07.
