We're dividing 58815721 by 150 
Our goal is to divide 58815721 by 150.

Going ahead to step 1:
The number 150 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 150

Moving on to step 2:
If we divide 58 by 150, we get 0 and a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 58 to get 58.
Bring next digit (8) of the dividend behind the 58 and repeat the process: 588 / 150

Moving on to step 3:
588 divided by 150 is 3 with a remainder of 138.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 450 from 588, we get 138.
Append the next digit (1) from the dividend to 138 and continue with: 1381 / 150

Advancing to step 4:
1381 divided by 150 is 9 with a remainder of 31.
The next digit of our result is 9. 
Result so far: 39.0
The remainder is 31 after subtracting 1350 from 1381.
Include the next digit (5) from the dividend after 31, then repeat: 315 / 150

Advancing to step 5:
150 can be fit into 315 2 times, resulting in a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 392.0
Deduct 300 from 315 and we're left with 15.
Grab the next digit (7) from the dividend, add it to 15, then carry on: 157 / 150

Advancing to step 6:
When dividing 157 by 150, we get 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 3921.0
Subtracting 150 from 157 leaves us with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 150

Let's proceed to step 7:
72 divided by 150 is 0 with a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 39210.0
Subtracting 0 from 72 leaves us with 72.
Grab the next digit (1) from the dividend, add it to 72, then carry on: 721 / 150

Step 8:
721 divided by 150 is 4 with a remainder of 121.
Write down 4 as next digit of the result. 
Result so far: 392104.0
If we take 600 away from 721, we end up with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

On to step 9:
150 can be fit into 1210 8 times, resulting in a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 392104.8
Subtract 1200 from 1210 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
150 can be fit into 100 0 times, resulting in a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 392104.8
If we subtract 0 from 100, we get 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 11:
150 can be fit into 1000 6 times, resulting in a remainder of 100.
The next digit of our result is 6. 
Result so far: 392104.806
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.

Advancing to step 12:
If we divide 1000 by 150, we get 6 and a remainder of 100.
Write down 6 as next digit of the result. 
Result so far: 392104.8066
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.

The final result is 392104.8066 with a remainder of 0.001.
