We look at the division of 81138462 by 906 
We're looking to find how many times 906 goes into 81138462.

Step 1:
906 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 906

Going ahead to step 2:
The number 906 fits into 81 0 times, leaving a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Include the next digit (1) from the dividend after 81, then repeat: 811 / 906

Let's proceed to step 3:
811 divided by 906 is 0 with a remainder of 811.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 811, we end up with 811.
Include the next digit (3) from the dividend after 811, then repeat: 8113 / 906

Step 4:
906 can be fit into 8113 8 times, resulting in a remainder of 865.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 7248 from 8113 to get 865.
Bring next digit (8) of the dividend behind the 865 and repeat the process: 8658 / 906

Let's proceed to step 5:
8658 divided by 906 is 9 with a remainder of 504.
Use 9 as the next digit of our solution. 
Result so far: 89.0
Subtracting 8154 from 8658 leaves us with 504.
Bring next digit (4) of the dividend behind the 504 and repeat the process: 5044 / 906

On to step 6:
When dividing 5044 by 906, we get 5 with a remainder of 514.
Record the quotient 5 as the next digit in the result. 
Result so far: 895.0
If we subtract 4530 from 5044, we get 514.
Fetch the next digit (6) from the dividend, attach it to 514 and continue: 5146 / 906

Moving on to step 7:
906 goes into 5146 5 times with a remainder of 616.
The number 5 becomes the next digit in our result. 
Result so far: 8955.0
Subtract 4530 from 5146 to get 616.
Take the next digit (2) from the dividend and append it to 616, then repeat: 6162 / 906

Step 8:
906 goes into 6162 6 times with a remainder of 726.
Use 6 as the next digit of our solution. 
Result so far: 89556.0
If we take 5436 away from 6162, we end up with 726.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7260, and continue the process.

Moving on to step 9:
906 goes into 7260 8 times with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 89556.8
Subtract 7248 from 7260 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 10:
906 goes into 120 0 times with a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 89556.8
Subtract 0 from 120 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 11:
1200 divided by 906 is 1 with a remainder of 294.
The next digit of our result is 1. 
Result so far: 89556.801
If we subtract 906 from 1200, we get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Moving on to step 12:
2940 divided by 906 is 3 with a remainder of 222.
Put 3 as the next digit of the answer. 
Result so far: 89556.8013
Subtract 2718 from 2940 to get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Going ahead to step 13:
The number 906 fits into 2220 2 times, leaving a remainder of 408.
Put 2 as the next digit of the answer. 
Result so far: 89556.80132
Subtract 1812 from 2220 to get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Advancing to step 14:
4080 divided by 906 is 4 with a remainder of 456.
Use 4 as the next digit of our solution. 
Result so far: 89556.801324
If we subtract 3624 from 4080, we get 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Advancing to step 15:
906 can be fit into 4560 5 times, resulting in a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 89556.8013245
Subtracting 4530 from 4560 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 16:
906 can be fit into 300 0 times, resulting in a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 89556.8013245
Subtract 0 from 300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final outcome is 89556.8013245, with a leftover of 3e-07.
