We look at the division of 13690749 by 851 
Let's see how many times 851 fits into 13690749.

Advancing to step 1:
If we divide 1 by 851, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 851

Step 2:
851 goes into 13 0 times with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 851

Step 3:
136 divided by 851 is 0 with a remainder of 136.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 136, we get 136.
Append the next digit (9) from the dividend to 136 and continue with: 1369 / 851

Advancing to step 4:
If we divide 1369 by 851, we get 1 and a remainder of 518.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 851 from 1369 leaves us with 518.
Take the next digit (0) from the dividend and append it to 518, then repeat: 5180 / 851

Advancing to step 5:
851 can be fit into 5180 6 times, resulting in a remainder of 74.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we subtract 5106 from 5180, we get 74.
Bring next digit (7) of the dividend behind the 74 and repeat the process: 747 / 851

Moving on to step 6:
851 can be fit into 747 0 times, resulting in a remainder of 747.
Record the quotient 0 as the next digit in the result. 
Result so far: 160.0
Subtracting 0 from 747 leaves us with 747.
Grab the next digit (4) from the dividend, add it to 747, then carry on: 7474 / 851

On to step 7:
When dividing 7474 by 851, we get 8 with a remainder of 666.
Put 8 as the next digit of the answer. 
Result so far: 1608.0
If we take 6808 away from 7474, we end up with 666.
Include the next digit (9) from the dividend after 666, then repeat: 6669 / 851

Advancing to step 8:
851 can be fit into 6669 7 times, resulting in a remainder of 712.
Use 7 as the next digit of our solution. 
Result so far: 16087.0
The remainder is 712 after subtracting 5957 from 6669.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

Advancing to step 9:
851 goes into 7120 8 times with a remainder of 312.
Use 8 as the next digit of our solution. 
Result so far: 16087.8
If we subtract 6808 from 7120, we get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Going ahead to step 10:
851 goes into 3120 3 times with a remainder of 567.
Write down 3 as next digit of the result. 
Result so far: 16087.83
The remainder is 567 after subtracting 2553 from 3120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

Going ahead to step 11:
When dividing 5670 by 851, we get 6 with a remainder of 564.
Put 6 as the next digit of the answer. 
Result so far: 16087.836
If we subtract 5106 from 5670, we get 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

On to step 12:
When dividing 5640 by 851, we get 6 with a remainder of 534.
The number 6 becomes the next digit in our result. 
Result so far: 16087.8366
If we take 5106 away from 5640, we end up with 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

The final outcome is 16087.8366, with a leftover of 0.00534.
