We're dividing 55891640 by 861 
We want to figure out the number of times 55891640 can be divided by 861.

Advancing to step 1:
If we divide 5 by 861, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 861

Advancing to step 2:
861 goes into 55 0 times with a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Grab the next digit (8) from the dividend, add it to 55, then carry on: 558 / 861

Step 3:
The number 861 fits into 558 0 times, leaving a remainder of 558.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 558 to get 558.
Append the next digit (9) from the dividend to 558 and continue with: 5589 / 861

Going ahead to step 4:
The number 861 fits into 5589 6 times, leaving a remainder of 423.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 5166 from 5589 leaves us with 423.
Bring next digit (1) of the dividend behind the 423 and repeat the process: 4231 / 861

On to step 5:
The number 861 fits into 4231 4 times, leaving a remainder of 787.
Put 4 as the next digit of the answer. 
Result so far: 64.0
If we take 3444 away from 4231, we end up with 787.
Append the next digit (6) from the dividend to 787 and continue with: 7876 / 861

Step 6:
861 goes into 7876 9 times with a remainder of 127.
Put 9 as the next digit of the answer. 
Result so far: 649.0
The remainder is 127 after subtracting 7749 from 7876.
Include the next digit (4) from the dividend after 127, then repeat: 1274 / 861

Moving on to step 7:
The number 861 fits into 1274 1 times, leaving a remainder of 413.
Write down 1 as next digit of the result. 
Result so far: 6491.0
Deduct 861 from 1274 and we're left with 413.
Include the next digit (0) from the dividend after 413, then repeat: 4130 / 861

Going ahead to step 8:
When dividing 4130 by 861, we get 4 with a remainder of 686.
Write down 4 as next digit of the result. 
Result so far: 64914.0
If we subtract 3444 from 4130, we get 686.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6860, and continue the process.

On to step 9:
861 can be fit into 6860 7 times, resulting in a remainder of 833.
Put 7 as the next digit of the answer. 
Result so far: 64914.7
If we take 6027 away from 6860, we end up with 833.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8330, and continue the process.

On to step 10:
When dividing 8330 by 861, we get 9 with a remainder of 581.
Use 9 as the next digit of our solution. 
Result so far: 64914.79
Subtracting 7749 from 8330 leaves us with 581.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5810, and continue the process.

Advancing to step 11:
861 goes into 5810 6 times with a remainder of 644.
Use 6 as the next digit of our solution. 
Result so far: 64914.796
If we subtract 5166 from 5810, we get 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Advancing to step 12:
The number 861 fits into 6440 7 times, leaving a remainder of 413.
Write down 7 as next digit of the result. 
Result so far: 64914.7967
If we take 6027 away from 6440, we end up with 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

Let's proceed to step 13:
861 goes into 4130 4 times with a remainder of 686.
Use 4 as the next digit of our solution. 
Result so far: 64914.79674
Subtracting 3444 from 4130 leaves us with 686.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6860, and continue the process.

Step 14:
861 can be fit into 6860 7 times, resulting in a remainder of 833.
Write down 7 as next digit of the result. 
Result so far: 64914.796747
Subtract 6027 from 6860 to get 833.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8330, and continue the process.

Moving on to step 15:
861 can be fit into 8330 9 times, resulting in a remainder of 581.
The number 9 becomes the next digit in our result. 
Result so far: 64914.7967479
The remainder is 581 after subtracting 7749 from 8330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5810, and continue the process.

On to step 16:
The number 861 fits into 5810 6 times, leaving a remainder of 644.
Put 6 as the next digit of the answer. 
Result so far: 64914.79674796
Subtract 5166 from 5810 to get 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Our division results in 64914.79674796 with a remaining 6.44e-07.
