We look at the division of 12521407 by 473 
We want to figure out the number of times 12521407 can be divided by 473.

Moving on to step 1:
When dividing 1 by 473, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 473

Going ahead to step 2:
473 goes into 12 0 times with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 473

Moving on to step 3:
When dividing 125 by 473, we get 0 with a remainder of 125.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 125, we end up with 125.
Bring next digit (2) of the dividend behind the 125 and repeat the process: 1252 / 473

Going ahead to step 4:
If we divide 1252 by 473, we get 2 and a remainder of 306.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 946 from 1252 to get 306.
Take the next digit (1) from the dividend and append it to 306, then repeat: 3061 / 473

Let's proceed to step 5:
473 goes into 3061 6 times with a remainder of 223.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
If we subtract 2838 from 3061, we get 223.
Take the next digit (4) from the dividend and append it to 223, then repeat: 2234 / 473

Let's proceed to step 6:
473 goes into 2234 4 times with a remainder of 342.
Put 4 as the next digit of the answer. 
Result so far: 264.0
Subtracting 1892 from 2234 leaves us with 342.
Include the next digit (0) from the dividend after 342, then repeat: 3420 / 473

Going ahead to step 7:
3420 divided by 473 is 7 with a remainder of 109.
Put 7 as the next digit of the answer. 
Result so far: 2647.0
If we take 3311 away from 3420, we end up with 109.
Fetch the next digit (7) from the dividend, attach it to 109 and continue: 1097 / 473

Going ahead to step 8:
The number 473 fits into 1097 2 times, leaving a remainder of 151.
Record the quotient 2 as the next digit in the result. 
Result so far: 26472.0
The remainder is 151 after subtracting 946 from 1097.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Let's proceed to step 9:
When dividing 1510 by 473, we get 3 with a remainder of 91.
Use 3 as the next digit of our solution. 
Result so far: 26472.3
Subtract 1419 from 1510 to get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

On to step 10:
473 goes into 910 1 times with a remainder of 437.
Record the quotient 1 as the next digit in the result. 
Result so far: 26472.31
If we take 473 away from 910, we end up with 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Moving on to step 11:
When dividing 4370 by 473, we get 9 with a remainder of 113.
Put 9 as the next digit of the answer. 
Result so far: 26472.319
Subtracting 4257 from 4370 leaves us with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Advancing to step 12:
473 goes into 1130 2 times with a remainder of 184.
Record the quotient 2 as the next digit in the result. 
Result so far: 26472.3192
If we take 946 away from 1130, we end up with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 13:
473 can be fit into 1840 3 times, resulting in a remainder of 421.
Use 3 as the next digit of our solution. 
Result so far: 26472.31923
Deduct 1419 from 1840 and we're left with 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

On to step 14:
473 goes into 4210 8 times with a remainder of 426.
Use 8 as the next digit of our solution. 
Result so far: 26472.319238
If we take 3784 away from 4210, we end up with 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Advancing to step 15:
If we divide 4260 by 473, we get 9 and a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 26472.3192389
The remainder is 3 after subtracting 4257 from 4260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 16:
473 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 26472.3192389
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

In conclusion, the division gives 26472.3192389 with a balance of 3e-08.
