85837395 divided by 166 
We want to figure out the number of times 85837395 can be divided by 166.

On to step 1:
166 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 166

Let's proceed to step 2:
When dividing 85 by 166, we get 0 with a remainder of 85.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Bring next digit (8) of the dividend behind the 85 and repeat the process: 858 / 166

Let's proceed to step 3:
When dividing 858 by 166, we get 5 with a remainder of 28.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 28 after subtracting 830 from 858.
Include the next digit (3) from the dividend after 28, then repeat: 283 / 166

Step 4:
166 goes into 283 1 times with a remainder of 117.
The next digit of our result is 1. 
Result so far: 51.0
If we subtract 166 from 283, we get 117.
Include the next digit (7) from the dividend after 117, then repeat: 1177 / 166

Moving on to step 5:
The number 166 fits into 1177 7 times, leaving a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 517.0
Deduct 1162 from 1177 and we're left with 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 166

On to step 6:
When dividing 153 by 166, we get 0 with a remainder of 153.
Use 0 as the next digit of our solution. 
Result so far: 5170.0
Deduct 0 from 153 and we're left with 153.
Append the next digit (9) from the dividend to 153 and continue with: 1539 / 166

Let's proceed to step 7:
166 goes into 1539 9 times with a remainder of 45.
Record the quotient 9 as the next digit in the result. 
Result so far: 51709.0
If we take 1494 away from 1539, we end up with 45.
Append the next digit (5) from the dividend to 45 and continue with: 455 / 166

Let's proceed to step 8:
When dividing 455 by 166, we get 2 with a remainder of 123.
The number 2 becomes the next digit in our result. 
Result so far: 517092.0
Subtract 332 from 455 to get 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Going ahead to step 9:
1230 divided by 166 is 7 with a remainder of 68.
Write down 7 as next digit of the result. 
Result so far: 517092.7
The remainder is 68 after subtracting 1162 from 1230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 10:
680 divided by 166 is 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 517092.74
If we subtract 664 from 680, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
If we divide 160 by 166, we get 0 and a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 517092.74
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 12:
If we divide 1600 by 166, we get 9 and a remainder of 106.
Use 9 as the next digit of our solution. 
Result so far: 517092.7409
If we take 1494 away from 1600, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 13:
When dividing 1060 by 166, we get 6 with a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 517092.74096
If we subtract 996 from 1060, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 14:
The number 166 fits into 640 3 times, leaving a remainder of 142.
The next digit of our result is 3. 
Result so far: 517092.740963
The remainder is 142 after subtracting 498 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Going ahead to step 15:
If we divide 1420 by 166, we get 8 and a remainder of 92.
Record the quotient 8 as the next digit in the result. 
Result so far: 517092.7409638
If we take 1328 away from 1420, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 16:
920 divided by 166 is 5 with a remainder of 90.
Put 5 as the next digit of the answer. 
Result so far: 517092.74096385
Subtract 830 from 920 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

After the division, we end up with 517092.74096385 and a remainder of 9e-08.
