86421124 divided by 150 
Our goal is to divide 86421124 by 150.

Advancing to step 1:
When dividing 8 by 150, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 150

Going ahead to step 2:
150 goes into 86 0 times with a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Fetch the next digit (4) from the dividend, attach it to 86 and continue: 864 / 150

Let's proceed to step 3:
When dividing 864 by 150, we get 5 with a remainder of 114.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 114 after subtracting 750 from 864.
Bring next digit (2) of the dividend behind the 114 and repeat the process: 1142 / 150

Step 4:
When dividing 1142 by 150, we get 7 with a remainder of 92.
Write down 7 as next digit of the result. 
Result so far: 57.0
Subtract 1050 from 1142 to get 92.
Bring next digit (1) of the dividend behind the 92 and repeat the process: 921 / 150

On to step 5:
921 divided by 150 is 6 with a remainder of 21.
Put 6 as the next digit of the answer. 
Result so far: 576.0
Deduct 900 from 921 and we're left with 21.
Append the next digit (1) from the dividend to 21 and continue with: 211 / 150

On to step 6:
If we divide 211 by 150, we get 1 and a remainder of 61.
Record the quotient 1 as the next digit in the result. 
Result so far: 5761.0
Subtract 150 from 211 to get 61.
Fetch the next digit (2) from the dividend, attach it to 61 and continue: 612 / 150

Step 7:
612 divided by 150 is 4 with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 57614.0
Subtracting 600 from 612 leaves us with 12.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 150

On to step 8:
When dividing 124 by 150, we get 0 with a remainder of 124.
Write down 0 as next digit of the result. 
Result so far: 576140.0
Subtracting 0 from 124 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.

Step 9:
1240 divided by 150 is 8 with a remainder of 40.
The next digit of our result is 8. 
Result so far: 576140.8
If we take 1200 away from 1240, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
If we divide 400 by 150, we get 2 and a remainder of 100.
The number 2 becomes the next digit in our result. 
Result so far: 576140.82
If we take 300 away from 400, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 11:
The number 150 fits into 1000 6 times, leaving a remainder of 100.
The next digit of our result is 6. 
Result so far: 576140.826
Deduct 900 from 1000 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 12:
1000 divided by 150 is 6 with a remainder of 100.
Write down 6 as next digit of the result. 
Result so far: 576140.8266
Subtracting 900 from 1000 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Our division results in 576140.8266 with a remaining 0.001.
