We look at the division of 13404727 by 851 
We want to figure out the number of times 13404727 can be divided by 851.

Step 1:
851 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 851

Step 2:
When dividing 13 by 851, we get 0 with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Take the next digit (4) from the dividend and append it to 13, then repeat: 134 / 851

Let's proceed to step 3:
The number 851 fits into 134 0 times, leaving a remainder of 134.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 134, we end up with 134.
Grab the next digit (0) from the dividend, add it to 134, then carry on: 1340 / 851

On to step 4:
1340 divided by 851 is 1 with a remainder of 489.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 851 away from 1340, we end up with 489.
Take the next digit (4) from the dividend and append it to 489, then repeat: 4894 / 851

Going ahead to step 5:
The number 851 fits into 4894 5 times, leaving a remainder of 639.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtract 4255 from 4894 to get 639.
Grab the next digit (7) from the dividend, add it to 639, then carry on: 6397 / 851

Let's proceed to step 6:
When dividing 6397 by 851, we get 7 with a remainder of 440.
Record the quotient 7 as the next digit in the result. 
Result so far: 157.0
The remainder is 440 after subtracting 5957 from 6397.
Append the next digit (2) from the dividend to 440 and continue with: 4402 / 851

On to step 7:
When dividing 4402 by 851, we get 5 with a remainder of 147.
Put 5 as the next digit of the answer. 
Result so far: 1575.0
Subtracting 4255 from 4402 leaves us with 147.
Take the next digit (7) from the dividend and append it to 147, then repeat: 1477 / 851

On to step 8:
851 goes into 1477 1 times with a remainder of 626.
Record the quotient 1 as the next digit in the result. 
Result so far: 15751.0
Subtracting 851 from 1477 leaves us with 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Let's proceed to step 9:
When dividing 6260 by 851, we get 7 with a remainder of 303.
Put 7 as the next digit of the answer. 
Result so far: 15751.7
If we take 5957 away from 6260, we end up with 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Advancing to step 10:
The number 851 fits into 3030 3 times, leaving a remainder of 477.
Use 3 as the next digit of our solution. 
Result so far: 15751.73
If we subtract 2553 from 3030, we get 477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

Advancing to step 11:
The number 851 fits into 4770 5 times, leaving a remainder of 515.
The next digit of our result is 5. 
Result so far: 15751.735
If we subtract 4255 from 4770, we get 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Advancing to step 12:
851 goes into 5150 6 times with a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 15751.7356
Deduct 5106 from 5150 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 13:
851 goes into 440 0 times with a remainder of 440.
Write down 0 as next digit of the result. 
Result so far: 15751.7356
Subtracting 0 from 440 leaves us with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 14:
When dividing 4400 by 851, we get 5 with a remainder of 145.
The number 5 becomes the next digit in our result. 
Result so far: 15751.735605
The remainder is 145 after subtracting 4255 from 4400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Going ahead to step 15:
The number 851 fits into 1450 1 times, leaving a remainder of 599.
Write down 1 as next digit of the result. 
Result so far: 15751.7356051
Deduct 851 from 1450 and we're left with 599.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5990, and continue the process.

Let's proceed to step 16:
The number 851 fits into 5990 7 times, leaving a remainder of 33.
Write down 7 as next digit of the result. 
Result so far: 15751.73560517
Deduct 5957 from 5990 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

In conclusion, the division gives 15751.73560517 with a balance of 3.3e-08.
