86370387 ÷ 133 
Our goal is to divide 86370387 by 133.

Let's proceed to step 1:
133 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 133

Advancing to step 2:
If we divide 86 by 133, we get 0 and a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Include the next digit (3) from the dividend after 86, then repeat: 863 / 133

Step 3:
The number 133 fits into 863 6 times, leaving a remainder of 65.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 798 from 863 to get 65.
Bring next digit (7) of the dividend behind the 65 and repeat the process: 657 / 133

Step 4:
657 divided by 133 is 4 with a remainder of 125.
Write down 4 as next digit of the result. 
Result so far: 64.0
Subtracting 532 from 657 leaves us with 125.
Grab the next digit (0) from the dividend, add it to 125, then carry on: 1250 / 133

Going ahead to step 5:
133 goes into 1250 9 times with a remainder of 53.
Put 9 as the next digit of the answer. 
Result so far: 649.0
If we take 1197 away from 1250, we end up with 53.
Bring next digit (3) of the dividend behind the 53 and repeat the process: 533 / 133

Step 6:
533 divided by 133 is 4 with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 6494.0
Subtracting 532 from 533 leaves us with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 133

Step 7:
If we divide 18 by 133, we get 0 and a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 64940.0
Subtracting 0 from 18 leaves us with 18.
Append the next digit (7) from the dividend to 18 and continue with: 187 / 133

On to step 8:
133 goes into 187 1 times with a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 649401.0
If we take 133 away from 187, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 9:
133 can be fit into 540 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 649401.4
If we take 532 away from 540, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
133 goes into 80 0 times with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 649401.4
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 11:
133 can be fit into 800 6 times, resulting in a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 649401.406
Subtracting 798 from 800 leaves us 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.

Step 12:
133 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 649401.406
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 13:
The number 133 fits into 200 1 times, leaving a remainder of 67.
Record the quotient 1 as the next digit in the result. 
Result so far: 649401.40601
Deduct 133 from 200 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 14:
If we divide 670 by 133, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 649401.406015
The remainder is 5 after subtracting 665 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 15:
133 goes into 50 0 times with a remainder of 50.
The next digit of our result is 0. 
Result so far: 649401.406015
Subtracting 0 from 50 leaves us with 50.
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 16:
When dividing 500 by 133, we get 3 with a remainder of 101.
Record the quotient 3 as the next digit in the result. 
Result so far: 649401.40601503
If we take 399 away from 500, we end up with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

The final outcome is 649401.40601503, with a leftover of 1.01e-07.
