81246586 divided by 158 
We want to divide 81246586 by 158.

Let's proceed to step 1:
158 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 158

Step 2:
81 divided by 158 is 0 with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Fetch the next digit (2) from the dividend, attach it to 81 and continue: 812 / 158

Going ahead to step 3:
The number 158 fits into 812 5 times, leaving a remainder of 22.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 790 from 812, we get 22.
Fetch the next digit (4) from the dividend, attach it to 22 and continue: 224 / 158

On to step 4:
If we divide 224 by 158, we get 1 and a remainder of 66.
The next digit of our result is 1. 
Result so far: 51.0
Subtract 158 from 224 to get 66.
Append the next digit (6) from the dividend to 66 and continue with: 666 / 158

Going ahead to step 5:
When dividing 666 by 158, we get 4 with a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 514.0
Deduct 632 from 666 and we're left with 34.
Bring next digit (5) of the dividend behind the 34 and repeat the process: 345 / 158

Step 6:
158 goes into 345 2 times with a remainder of 29.
Write down 2 as next digit of the result. 
Result so far: 5142.0
Deduct 316 from 345 and we're left with 29.
Include the next digit (8) from the dividend after 29, then repeat: 298 / 158

Step 7:
158 can be fit into 298 1 times, resulting in a remainder of 140.
The number 1 becomes the next digit in our result. 
Result so far: 51421.0
If we subtract 158 from 298, we get 140.
Grab the next digit (6) from the dividend, add it to 140, then carry on: 1406 / 158

Let's proceed to step 8:
158 goes into 1406 8 times with a remainder of 142.
Use 8 as the next digit of our solution. 
Result so far: 514218.0
If we subtract 1264 from 1406, we get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Moving on to step 9:
158 goes into 1420 8 times with a remainder of 156.
Record the quotient 8 as the next digit in the result. 
Result so far: 514218.8
If we take 1264 away from 1420, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Let's proceed to step 10:
158 goes into 1560 9 times with a remainder of 138.
Record the quotient 9 as the next digit in the result. 
Result so far: 514218.89
The remainder is 138 after subtracting 1422 from 1560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Step 11:
158 goes into 1380 8 times with a remainder of 116.
The number 8 becomes the next digit in our result. 
Result so far: 514218.898
If we take 1264 away from 1380, we end up with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 12:
158 can be fit into 1160 7 times, resulting in a remainder of 54.
Record the quotient 7 as the next digit in the result. 
Result so far: 514218.8987
If we take 1106 away from 1160, 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.

On to step 13:
When dividing 540 by 158, we get 3 with a remainder of 66.
The next digit of our result is 3. 
Result so far: 514218.89873
Deduct 474 from 540 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 14:
If we divide 660 by 158, we get 4 and a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 514218.898734
If we take 632 away from 660, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 15:
280 divided by 158 is 1 with a remainder of 122.
The next digit of our result is 1. 
Result so far: 514218.8987341
Subtract 158 from 280 to get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Step 16:
If we divide 1220 by 158, we get 7 and a remainder of 114.
Record the quotient 7 as the next digit in the result. 
Result so far: 514218.89873417
If we subtract 1106 from 1220, we get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

The quotient of the division is 514218.89873417, and the remainder is 1.14e-07.
