Let's divide 77610351 by 901
We want to divide 77610351 by 901.

Moving on to step 1:
When dividing 7 by 901, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 901

On to step 2:
77 divided by 901 is 0 with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Include the next digit (6) from the dividend after 77, then repeat: 776 / 901

Advancing to step 3:
The number 901 fits into 776 0 times, leaving a remainder of 776.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 776, we end up with 776.
Take the next digit (1) from the dividend and append it to 776, then repeat: 7761 / 901

Step 4:
7761 divided by 901 is 8 with a remainder of 553.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 7208 from 7761 to get 553.
Bring next digit (0) of the dividend behind the 553 and repeat the process: 5530 / 901

Step 5:
901 can be fit into 5530 6 times, resulting in a remainder of 124.
Write down 6 as next digit of the result. 
Result so far: 86.0
If we take 5406 away from 5530, we end up with 124.
Fetch the next digit (3) from the dividend, attach it to 124 and continue: 1243 / 901

Going ahead to step 6:
When dividing 1243 by 901, we get 1 with a remainder of 342.
The next digit of our result is 1. 
Result so far: 861.0
Deduct 901 from 1243 and we're left with 342.
Fetch the next digit (5) from the dividend, attach it to 342 and continue: 3425 / 901

Going ahead to step 7:
If we divide 3425 by 901, we get 3 and a remainder of 722.
Put 3 as the next digit of the answer. 
Result so far: 8613.0
If we take 2703 away from 3425, we end up with 722.
Include the next digit (1) from the dividend after 722, then repeat: 7221 / 901

Advancing to step 8:
901 can be fit into 7221 8 times, resulting in a remainder of 13.
The next digit of our result is 8. 
Result so far: 86138.0
Subtracting 7208 from 7221 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 9:
901 can be fit into 130 0 times, resulting in a remainder of 130.
The next digit of our result is 0. 
Result so far: 86138.0
Subtract 0 from 130 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 10:
When dividing 1300 by 901, we get 1 with a remainder of 399.
The next digit of our result is 1. 
Result so far: 86138.01
The remainder is 399 after subtracting 901 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

On to step 11:
The number 901 fits into 3990 4 times, leaving a remainder of 386.
The next digit of our result is 4. 
Result so far: 86138.014
Deduct 3604 from 3990 and we're left with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

On to step 12:
The number 901 fits into 3860 4 times, leaving a remainder of 256.
Write down 4 as next digit of the result. 
Result so far: 86138.0144
Subtract 3604 from 3860 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

In conclusion, the division gives 86138.0144 with a balance of 0.00256.
