We look at the division of 55453366 by 861 
We want to divide 55453366 by 861.

Advancing to step 1:
When dividing 5 by 861, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 861

Advancing to step 2:
55 divided by 861 is 0 with a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Take the next digit (4) from the dividend and append it to 55, then repeat: 554 / 861

Moving on to step 3:
The number 861 fits into 554 0 times, leaving a remainder of 554.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 554, we get 554.
Include the next digit (5) from the dividend after 554, then repeat: 5545 / 861

On to step 4:
The number 861 fits into 5545 6 times, leaving a remainder of 379.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 5166 away from 5545, we end up with 379.
Include the next digit (3) from the dividend after 379, then repeat: 3793 / 861

Moving on to step 5:
If we divide 3793 by 861, we get 4 and a remainder of 349.
The next digit of our result is 4. 
Result so far: 64.0
If we take 3444 away from 3793, we end up with 349.
Include the next digit (3) from the dividend after 349, then repeat: 3493 / 861

Moving on to step 6:
3493 divided by 861 is 4 with a remainder of 49.
Record the quotient 4 as the next digit in the result. 
Result so far: 644.0
Subtract 3444 from 3493 to get 49.
Bring next digit (6) of the dividend behind the 49 and repeat the process: 496 / 861

Advancing to step 7:
861 goes into 496 0 times with a remainder of 496.
Use 0 as the next digit of our solution. 
Result so far: 6440.0
Subtract 0 from 496 to get 496.
Grab the next digit (6) from the dividend, add it to 496, then carry on: 4966 / 861

Step 8:
861 can be fit into 4966 5 times, resulting in a remainder of 661.
Use 5 as the next digit of our solution. 
Result so far: 64405.0
If we take 4305 away from 4966, we end up with 661.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6610, and continue the process.

Moving on to step 9:
When dividing 6610 by 861, we get 7 with a remainder of 583.
The number 7 becomes the next digit in our result. 
Result so far: 64405.7
If we subtract 6027 from 6610, we get 583.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5830, and continue the process.

Moving on to step 10:
861 can be fit into 5830 6 times, resulting in a remainder of 664.
The number 6 becomes the next digit in our result. 
Result so far: 64405.76
If we take 5166 away from 5830, we end up with 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

Going ahead to step 11:
The number 861 fits into 6640 7 times, leaving a remainder of 613.
The number 7 becomes the next digit in our result. 
Result so far: 64405.767
Deduct 6027 from 6640 and we're left with 613.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6130, and continue the process.

Step 12:
If we divide 6130 by 861, we get 7 and a remainder of 103.
The next digit of our result is 7. 
Result so far: 64405.7677
Subtracting 6027 from 6130 leaves us with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

In conclusion, the division gives 64405.7677 with a balance of 0.00103.
