Let's divide 75831238 by 166
We want to divide 75831238 by 166.

On to step 1:
166 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 166

Moving on to step 2:
When dividing 75 by 166, we get 0 with a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 75 leaves us with 75.
Include the next digit (8) from the dividend after 75, then repeat: 758 / 166

Advancing to step 3:
If we divide 758 by 166, we get 4 and a remainder of 94.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 664 from 758 and we're left with 94.
Append the next digit (3) from the dividend to 94 and continue with: 943 / 166

Advancing to step 4:
166 can be fit into 943 5 times, resulting in a remainder of 113.
Write down 5 as next digit of the result. 
Result so far: 45.0
If we take 830 away from 943, we end up with 113.
Fetch the next digit (1) from the dividend, attach it to 113 and continue: 1131 / 166

On to step 5:
166 can be fit into 1131 6 times, resulting in a remainder of 135.
The next digit of our result is 6. 
Result so far: 456.0
Subtract 996 from 1131 to get 135.
Bring next digit (2) of the dividend behind the 135 and repeat the process: 1352 / 166

Let's proceed to step 6:
166 can be fit into 1352 8 times, resulting in a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 4568.0
Subtracting 1328 from 1352 leaves us with 24.
Bring next digit (3) of the dividend behind the 24 and repeat the process: 243 / 166

Advancing to step 7:
When dividing 243 by 166, we get 1 with a remainder of 77.
Use 1 as the next digit of our solution. 
Result so far: 45681.0
Subtracting 166 from 243 leaves us with 77.
Grab the next digit (8) from the dividend, add it to 77, then carry on: 778 / 166

Advancing to step 8:
166 goes into 778 4 times with a remainder of 114.
Record the quotient 4 as the next digit in the result. 
Result so far: 456814.0
The remainder is 114 after subtracting 664 from 778.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Step 9:
166 goes into 1140 6 times with a remainder of 144.
The number 6 becomes the next digit in our result. 
Result so far: 456814.6
If we subtract 996 from 1140, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 10:
1440 divided by 166 is 8 with a remainder of 112.
The number 8 becomes the next digit in our result. 
Result so far: 456814.68
If we subtract 1328 from 1440, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 11:
166 goes into 1120 6 times with a remainder of 124.
Write down 6 as next digit of the result. 
Result so far: 456814.686
Subtracting 996 from 1120 leaves us with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Advancing to step 12:
When dividing 1240 by 166, we get 7 with a remainder of 78.
Write down 7 as next digit of the result. 
Result so far: 456814.6867
If we subtract 1162 from 1240, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 13:
166 goes into 780 4 times with a remainder of 116.
Put 4 as the next digit of the answer. 
Result so far: 456814.68674
Subtract 664 from 780 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

On to step 14:
The number 166 fits into 1160 6 times, leaving a remainder of 164.
Write down 6 as next digit of the result. 
Result so far: 456814.686746
Subtract 996 from 1160 to get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Moving on to step 15:
The number 166 fits into 1640 9 times, leaving a remainder of 146.
Put 9 as the next digit of the answer. 
Result so far: 456814.6867469
The remainder is 146 after subtracting 1494 from 1640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Advancing to step 16:
166 goes into 1460 8 times with a remainder of 132.
Write down 8 as next digit of the result. 
Result so far: 456814.68674698
If we take 1328 away from 1460, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

The final outcome is 456814.68674698, with a leftover of 1.32e-07.
