We're dividing 15210059 by 517 
We want to divide 15210059 by 517.

Let's proceed to step 1:
If we divide 1 by 517, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 517

Going ahead to step 2:
517 goes into 15 0 times with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Bring next digit (2) of the dividend behind the 15 and repeat the process: 152 / 517

Advancing to step 3:
The number 517 fits into 152 0 times, leaving a remainder of 152.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 152, we get 152.
Grab the next digit (1) from the dividend, add it to 152, then carry on: 1521 / 517

Step 4:
When dividing 1521 by 517, we get 2 with a remainder of 487.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 1034 from 1521 and we're left with 487.
Grab the next digit (0) from the dividend, add it to 487, then carry on: 4870 / 517

Moving on to step 5:
4870 divided by 517 is 9 with a remainder of 217.
Write down 9 as next digit of the result. 
Result so far: 29.0
Deduct 4653 from 4870 and we're left with 217.
Bring next digit (0) of the dividend behind the 217 and repeat the process: 2170 / 517

Advancing to step 6:
517 can be fit into 2170 4 times, resulting in a remainder of 102.
Write down 4 as next digit of the result. 
Result so far: 294.0
If we subtract 2068 from 2170, we get 102.
Fetch the next digit (5) from the dividend, attach it to 102 and continue: 1025 / 517

Moving on to step 7:
1025 divided by 517 is 1 with a remainder of 508.
The number 1 becomes the next digit in our result. 
Result so far: 2941.0
Subtract 517 from 1025 to get 508.
Fetch the next digit (9) from the dividend, attach it to 508 and continue: 5089 / 517

Advancing to step 8:
If we divide 5089 by 517, we get 9 and a remainder of 436.
Record the quotient 9 as the next digit in the result. 
Result so far: 29419.0
Subtracting 4653 from 5089 leaves us with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Let's proceed to step 9:
If we divide 4360 by 517, we get 8 and a remainder of 224.
Put 8 as the next digit of the answer. 
Result so far: 29419.8
Subtract 4136 from 4360 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Let's proceed to step 10:
When dividing 2240 by 517, we get 4 with a remainder of 172.
Put 4 as the next digit of the answer. 
Result so far: 29419.84
The remainder is 172 after subtracting 2068 from 2240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

On to step 11:
The number 517 fits into 1720 3 times, leaving a remainder of 169.
Put 3 as the next digit of the answer. 
Result so far: 29419.843
Deduct 1551 from 1720 and we're left with 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Step 12:
517 goes into 1690 3 times with a remainder of 139.
Use 3 as the next digit of our solution. 
Result so far: 29419.8433
If we take 1551 away from 1690, we end up with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

In conclusion, the division gives 29419.8433 with a balance of 0.00139.
