Let's divide 66474947 by 851
We're looking to find how many times 851 goes into 66474947.

Moving on to step 1:
When dividing 6 by 851, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 851

On to step 2:
The number 851 fits into 66 0 times, leaving a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Bring next digit (4) of the dividend behind the 66 and repeat the process: 664 / 851

Going ahead to step 3:
If we divide 664 by 851, we get 0 and a remainder of 664.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 664 after subtracting 0 from 664.
Grab the next digit (7) from the dividend, add it to 664, then carry on: 6647 / 851

Let's proceed to step 4:
6647 divided by 851 is 7 with a remainder of 690.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 5957 away from 6647, we end up with 690.
Take the next digit (4) from the dividend and append it to 690, then repeat: 6904 / 851

Step 5:
6904 divided by 851 is 8 with a remainder of 96.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
The remainder is 96 after subtracting 6808 from 6904.
Take the next digit (9) from the dividend and append it to 96, then repeat: 969 / 851

On to step 6:
The number 851 fits into 969 1 times, leaving a remainder of 118.
Record the quotient 1 as the next digit in the result. 
Result so far: 781.0
Subtract 851 from 969 to get 118.
Take the next digit (4) from the dividend and append it to 118, then repeat: 1184 / 851

Step 7:
851 goes into 1184 1 times with a remainder of 333.
Record the quotient 1 as the next digit in the result. 
Result so far: 7811.0
Deduct 851 from 1184 and we're left with 333.
Take the next digit (7) from the dividend and append it to 333, then repeat: 3337 / 851

Step 8:
851 can be fit into 3337 3 times, resulting in a remainder of 784.
Record the quotient 3 as the next digit in the result. 
Result so far: 78113.0
Subtract 2553 from 3337 to get 784.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

On to step 9:
7840 divided by 851 is 9 with a remainder of 181.
Write down 9 as next digit of the result. 
Result so far: 78113.9
Subtract 7659 from 7840 to get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Going ahead to step 10:
1810 divided by 851 is 2 with a remainder of 108.
Record the quotient 2 as the next digit in the result. 
Result so far: 78113.92
Deduct 1702 from 1810 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 11:
851 goes into 1080 1 times with a remainder of 229.
Put 1 as the next digit of the answer. 
Result so far: 78113.921
If we subtract 851 from 1080, we get 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Going ahead to step 12:
851 can be fit into 2290 2 times, resulting in a remainder of 588.
Write down 2 as next digit of the result. 
Result so far: 78113.9212
The remainder is 588 after subtracting 1702 from 2290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Going ahead to step 13:
5880 divided by 851 is 6 with a remainder of 774.
Use 6 as the next digit of our solution. 
Result so far: 78113.92126
Subtract 5106 from 5880 to get 774.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7740, and continue the process.

On to step 14:
7740 divided by 851 is 9 with a remainder of 81.
The next digit of our result is 9. 
Result so far: 78113.921269
Subtract 7659 from 7740 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 15:
810 divided by 851 is 0 with a remainder of 810.
Use 0 as the next digit of our solution. 
Result so far: 78113.921269
Deduct 0 from 810 and we're left with 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

On to step 16:
851 goes into 8100 9 times with a remainder of 441.
Write down 9 as next digit of the result. 
Result so far: 78113.92126909
Deduct 7659 from 8100 and we're left with 441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

The final outcome is 78113.92126909, with a leftover of 4.41e-07.
