15486722 ÷ 851 
We want to divide 15486722 by 851.

Let's proceed to step 1:
If we divide 1 by 851, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 851

On to step 2:
851 goes into 15 0 times with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Append the next digit (4) from the dividend to 15 and continue with: 154 / 851

Moving on to step 3:
851 goes into 154 0 times with a remainder of 154.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 154 and we're left with 154.
Bring next digit (8) of the dividend behind the 154 and repeat the process: 1548 / 851

Step 4:
851 can be fit into 1548 1 times, resulting in a remainder of 697.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 851 from 1548 and we're left with 697.
Bring next digit (6) of the dividend behind the 697 and repeat the process: 6976 / 851

Step 5:
The number 851 fits into 6976 8 times, leaving a remainder of 168.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtract 6808 from 6976 to get 168.
Grab the next digit (7) from the dividend, add it to 168, then carry on: 1687 / 851

Moving on to step 6:
851 can be fit into 1687 1 times, resulting in a remainder of 836.
The next digit of our result is 1. 
Result so far: 181.0
Subtracting 851 from 1687 leaves us with 836.
Include the next digit (2) from the dividend after 836, then repeat: 8362 / 851

Going ahead to step 7:
If we divide 8362 by 851, we get 9 and a remainder of 703.
Use 9 as the next digit of our solution. 
Result so far: 1819.0
Deduct 7659 from 8362 and we're left with 703.
Fetch the next digit (2) from the dividend, attach it to 703 and continue: 7032 / 851

Going ahead to step 8:
851 can be fit into 7032 8 times, resulting in a remainder of 224.
Put 8 as the next digit of the answer. 
Result so far: 18198.0
Deduct 6808 from 7032 and we're left with 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 9:
When dividing 2240 by 851, we get 2 with a remainder of 538.
The next digit of our result is 2. 
Result so far: 18198.2
Deduct 1702 from 2240 and we're left with 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Going ahead to step 10:
The number 851 fits into 5380 6 times, leaving a remainder of 274.
The next digit of our result is 6. 
Result so far: 18198.26
The remainder is 274 after subtracting 5106 from 5380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Advancing to step 11:
When dividing 2740 by 851, we get 3 with a remainder of 187.
Put 3 as the next digit of the answer. 
Result so far: 18198.263
Deduct 2553 from 2740 and we're left with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

On to step 12:
If we divide 1870 by 851, we get 2 and a remainder of 168.
Write down 2 as next digit of the result. 
Result so far: 18198.2632
Subtract 1702 from 1870 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Let's proceed to step 13:
851 can be fit into 1680 1 times, resulting in a remainder of 829.
Put 1 as the next digit of the answer. 
Result so far: 18198.26321
If we subtract 851 from 1680, we get 829.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8290, and continue the process.

On to step 14:
851 can be fit into 8290 9 times, resulting in a remainder of 631.
Write down 9 as next digit of the result. 
Result so far: 18198.263219
Subtract 7659 from 8290 to get 631.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6310, and continue the process.

Moving on to step 15:
If we divide 6310 by 851, we get 7 and a remainder of 353.
The number 7 becomes the next digit in our result. 
Result so far: 18198.2632197
If we subtract 5957 from 6310, we get 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

On to step 16:
When dividing 3530 by 851, we get 4 with a remainder of 126.
Write down 4 as next digit of the result. 
Result so far: 18198.26321974
The remainder is 126 after subtracting 3404 from 3530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

The final outcome is 18198.26321974, with a leftover of 1.26e-07.
