78702037 divided by 166 
We want to divide 78702037 by 166.

Moving on to step 1:
The number 166 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 166

Going ahead to step 2:
166 can be fit into 78 0 times, resulting in a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Bring next digit (7) of the dividend behind the 78 and repeat the process: 787 / 166

On to step 3:
If we divide 787 by 166, we get 4 and a remainder of 123.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 664 from 787, we get 123.
Fetch the next digit (0) from the dividend, attach it to 123 and continue: 1230 / 166

Moving on to step 4:
166 goes into 1230 7 times with a remainder of 68.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
Deduct 1162 from 1230 and we're left with 68.
Take the next digit (2) from the dividend and append it to 68, then repeat: 682 / 166

Let's proceed to step 5:
166 can be fit into 682 4 times, resulting in a remainder of 18.
The next digit of our result is 4. 
Result so far: 474.0
Deduct 664 from 682 and we're left with 18.
Append the next digit (0) from the dividend to 18 and continue with: 180 / 166

Moving on to step 6:
180 divided by 166 is 1 with a remainder of 14.
The next digit of our result is 1. 
Result so far: 4741.0
Deduct 166 from 180 and we're left with 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 166

Let's proceed to step 7:
The number 166 fits into 143 0 times, leaving a remainder of 143.
Use 0 as the next digit of our solution. 
Result so far: 47410.0
Subtracting 0 from 143 leaves us with 143.
Include the next digit (7) from the dividend after 143, then repeat: 1437 / 166

Advancing to step 8:
The number 166 fits into 1437 8 times, leaving a remainder of 109.
Record the quotient 8 as the next digit in the result. 
Result so far: 474108.0
If we subtract 1328 from 1437, we get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Advancing to step 9:
166 can be fit into 1090 6 times, resulting in a remainder of 94.
Put 6 as the next digit of the answer. 
Result so far: 474108.6
Deduct 996 from 1090 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Step 10:
166 can be fit into 940 5 times, resulting in a remainder of 110.
Use 5 as the next digit of our solution. 
Result so far: 474108.65
The remainder is 110 after subtracting 830 from 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 11:
The number 166 fits into 1100 6 times, leaving a remainder of 104.
The next digit of our result is 6. 
Result so far: 474108.656
Subtract 996 from 1100 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 12:
166 can be fit into 1040 6 times, resulting in a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 474108.6566
Subtracting 996 from 1040 leaves us 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.

The final result is 474108.6566 with a remainder of 0.00044.
