Let's divide 75386369 by 166
We want to figure out the number of times 75386369 can be divided by 166.

Going ahead to step 1:
When dividing 7 by 166, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 166

Moving on to step 2:
166 can be fit into 75 0 times, resulting in a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 75, we end up with 75.
Fetch the next digit (3) from the dividend, attach it to 75 and continue: 753 / 166

Let's proceed to step 3:
If we divide 753 by 166, we get 4 and a remainder of 89.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 89 after subtracting 664 from 753.
Grab the next digit (8) from the dividend, add it to 89, then carry on: 898 / 166

Advancing to step 4:
898 divided by 166 is 5 with a remainder of 68.
Put 5 as the next digit of the answer. 
Result so far: 45.0
Subtracting 830 from 898 leaves us with 68.
Include the next digit (6) from the dividend after 68, then repeat: 686 / 166

Let's proceed to step 5:
If we divide 686 by 166, we get 4 and a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 454.0
The remainder is 22 after subtracting 664 from 686.
Fetch the next digit (3) from the dividend, attach it to 22 and continue: 223 / 166

Let's proceed to step 6:
166 goes into 223 1 times with a remainder of 57.
Write down 1 as next digit of the result. 
Result so far: 4541.0
Deduct 166 from 223 and we're left with 57.
Bring next digit (6) of the dividend behind the 57 and repeat the process: 576 / 166

Going ahead to step 7:
166 can be fit into 576 3 times, resulting in a remainder of 78.
Record the quotient 3 as the next digit in the result. 
Result so far: 45413.0
If we subtract 498 from 576, we get 78.
Fetch the next digit (9) from the dividend, attach it to 78 and continue: 789 / 166

On to step 8:
If we divide 789 by 166, we get 4 and a remainder of 125.
Put 4 as the next digit of the answer. 
Result so far: 454134.0
If we take 664 away from 789, we end up with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 9:
When dividing 1250 by 166, we get 7 with a remainder of 88.
The next digit of our result is 7. 
Result so far: 454134.7
If we subtract 1162 from 1250, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 10:
The number 166 fits into 880 5 times, leaving a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 454134.75
The remainder is 50 after subtracting 830 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 11:
166 goes into 500 3 times with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 454134.753
If we take 498 away from 500, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 12:
The number 166 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 454134.753
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 13:
166 can be fit into 200 1 times, resulting in a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 454134.75301
Deduct 166 from 200 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 14:
The number 166 fits into 340 2 times, leaving a remainder of 8.
The next digit of our result is 2. 
Result so far: 454134.753012
Subtract 332 from 340 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 15:
80 divided by 166 is 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 454134.753012
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 16:
166 goes into 800 4 times with a remainder of 136.
Record the quotient 4 as the next digit in the result. 
Result so far: 454134.75301204
Deduct 664 from 800 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Our division results in 454134.75301204 with a remaining 1.36e-07.
