We divide 77021681 by 906
We want to figure out the number of times 77021681 can be divided by 906.

Let's proceed to step 1:
When dividing 7 by 906, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 906

Going ahead to step 2:
77 divided by 906 is 0 with a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Include the next digit (0) from the dividend after 77, then repeat: 770 / 906

Going ahead to step 3:
If we divide 770 by 906, we get 0 and a remainder of 770.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 770 leaves us with 770.
Bring next digit (2) of the dividend behind the 770 and repeat the process: 7702 / 906

Going ahead to step 4:
906 can be fit into 7702 8 times, resulting in a remainder of 454.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 7248 from 7702, we get 454.
Grab the next digit (1) from the dividend, add it to 454, then carry on: 4541 / 906

Going ahead to step 5:
906 goes into 4541 5 times with a remainder of 11.
Record the quotient 5 as the next digit in the result. 
Result so far: 85.0
The remainder is 11 after subtracting 4530 from 4541.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 906

Let's proceed to step 6:
906 can be fit into 116 0 times, resulting in a remainder of 116.
The number 0 becomes the next digit in our result. 
Result so far: 850.0
Subtract 0 from 116 to get 116.
Append the next digit (8) from the dividend to 116 and continue with: 1168 / 906

Step 7:
The number 906 fits into 1168 1 times, leaving a remainder of 262.
Record the quotient 1 as the next digit in the result. 
Result so far: 8501.0
The remainder is 262 after subtracting 906 from 1168.
Append the next digit (1) from the dividend to 262 and continue with: 2621 / 906

Let's proceed to step 8:
906 can be fit into 2621 2 times, resulting in a remainder of 809.
Put 2 as the next digit of the answer. 
Result so far: 85012.0
Subtracting 1812 from 2621 leaves us with 809.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8090, and continue the process.

Moving on to step 9:
When dividing 8090 by 906, we get 8 with a remainder of 842.
The number 8 becomes the next digit in our result. 
Result so far: 85012.8
Deduct 7248 from 8090 and we're left with 842.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8420, and continue the process.

Let's proceed to step 10:
906 goes into 8420 9 times with a remainder of 266.
Record the quotient 9 as the next digit in the result. 
Result so far: 85012.89
Subtract 8154 from 8420 to get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Let's proceed to step 11:
The number 906 fits into 2660 2 times, leaving a remainder of 848.
Record the quotient 2 as the next digit in the result. 
Result so far: 85012.892
Subtracting 1812 from 2660 leaves us with 848.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8480, and continue the process.

Going ahead to step 12:
906 goes into 8480 9 times with a remainder of 326.
Write down 9 as next digit of the result. 
Result so far: 85012.8929
Deduct 8154 from 8480 and we're left with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

On to step 13:
906 can be fit into 3260 3 times, resulting in a remainder of 542.
Write down 3 as next digit of the result. 
Result so far: 85012.89293
Subtracting 2718 from 3260 leaves us with 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

Let's proceed to step 14:
5420 divided by 906 is 5 with a remainder of 890.
The number 5 becomes the next digit in our result. 
Result so far: 85012.892935
The remainder is 890 after subtracting 4530 from 5420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8900, and continue the process.

Let's proceed to step 15:
906 goes into 8900 9 times with a remainder of 746.
The number 9 becomes the next digit in our result. 
Result so far: 85012.8929359
If we subtract 8154 from 8900, we get 746.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7460, and continue the process.

Step 16:
If we divide 7460 by 906, we get 8 and a remainder of 212.
The next digit of our result is 8. 
Result so far: 85012.89293598
Subtract 7248 from 7460 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

In conclusion, the division gives 85012.89293598 with a balance of 2.12e-07.
