61555659 ÷ 873 
We want to divide 61555659 by 873.

Moving on to step 1:
6 divided by 873 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 873

Moving on to step 2:
When dividing 61 by 873, we get 0 with a remainder of 61.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 61 to get 61.
Include the next digit (5) from the dividend after 61, then repeat: 615 / 873

On to step 3:
873 goes into 615 0 times with a remainder of 615.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 615 leaves us with 615.
Grab the next digit (5) from the dividend, add it to 615, then carry on: 6155 / 873

Let's proceed to step 4:
When dividing 6155 by 873, we get 7 with a remainder of 44.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 6111 from 6155 to get 44.
Append the next digit (5) from the dividend to 44 and continue with: 445 / 873

Step 5:
445 divided by 873 is 0 with a remainder of 445.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
The remainder is 445 after subtracting 0 from 445.
Fetch the next digit (6) from the dividend, attach it to 445 and continue: 4456 / 873

Advancing to step 6:
873 goes into 4456 5 times with a remainder of 91.
Record the quotient 5 as the next digit in the result. 
Result so far: 705.0
The remainder is 91 after subtracting 4365 from 4456.
Take the next digit (5) from the dividend and append it to 91, then repeat: 915 / 873

Moving on to step 7:
If we divide 915 by 873, we get 1 and a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 7051.0
If we take 873 away from 915, we end up with 42.
Take the next digit (9) from the dividend and append it to 42, then repeat: 429 / 873

Moving on to step 8:
873 goes into 429 0 times with a remainder of 429.
The next digit of our result is 0. 
Result so far: 70510.0
Subtract 0 from 429 to get 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Going ahead to step 9:
873 goes into 4290 4 times with a remainder of 798.
The number 4 becomes the next digit in our result. 
Result so far: 70510.4
Subtract 3492 from 4290 to get 798.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7980, and continue the process.

Step 10:
873 can be fit into 7980 9 times, resulting in a remainder of 123.
Use 9 as the next digit of our solution. 
Result so far: 70510.49
Subtracting 7857 from 7980 leaves us with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Step 11:
If we divide 1230 by 873, we get 1 and a remainder of 357.
Record the quotient 1 as the next digit in the result. 
Result so far: 70510.491
Deduct 873 from 1230 and we're left with 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Advancing to step 12:
873 goes into 3570 4 times with a remainder of 78.
Put 4 as the next digit of the answer. 
Result so far: 70510.4914
If we take 3492 away from 3570, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 13:
873 goes into 780 0 times with a remainder of 780.
The number 0 becomes the next digit in our result. 
Result so far: 70510.4914
Subtract 0 from 780 to get 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Step 14:
The number 873 fits into 7800 8 times, leaving a remainder of 816.
Put 8 as the next digit of the answer. 
Result so far: 70510.491408
If we subtract 6984 from 7800, we get 816.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8160, and continue the process.

Step 15:
8160 divided by 873 is 9 with a remainder of 303.
The next digit of our result is 9. 
Result so far: 70510.4914089
If we take 7857 away from 8160, we end up with 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Let's proceed to step 16:
If we divide 3030 by 873, we get 3 and a remainder of 411.
Record the quotient 3 as the next digit in the result. 
Result so far: 70510.49140893
If we subtract 2619 from 3030, we get 411.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

The final outcome is 70510.49140893, with a leftover of 4.11e-07.
