We're dividing 84403821 by 861 
We're looking to find how many times 861 goes into 84403821.

Let's proceed to step 1:
If we divide 8 by 861, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 861

Step 2:
The number 861 fits into 84 0 times, leaving a remainder of 84.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 84 after subtracting 0 from 84.
Fetch the next digit (4) from the dividend, attach it to 84 and continue: 844 / 861

Advancing to step 3:
If we divide 844 by 861, we get 0 and a remainder of 844.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 844, we end up with 844.
Bring next digit (0) of the dividend behind the 844 and repeat the process: 8440 / 861

Moving on to step 4:
861 can be fit into 8440 9 times, resulting in a remainder of 691.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 691 after subtracting 7749 from 8440.
Append the next digit (3) from the dividend to 691 and continue with: 6913 / 861

Let's proceed to step 5:
861 can be fit into 6913 8 times, resulting in a remainder of 25.
Write down 8 as next digit of the result. 
Result so far: 98.0
If we take 6888 away from 6913, we end up with 25.
Take the next digit (8) from the dividend and append it to 25, then repeat: 258 / 861

Advancing to step 6:
The number 861 fits into 258 0 times, leaving a remainder of 258.
Write down 0 as next digit of the result. 
Result so far: 980.0
If we subtract 0 from 258, we get 258.
Fetch the next digit (2) from the dividend, attach it to 258 and continue: 2582 / 861

Advancing to step 7:
861 can be fit into 2582 2 times, resulting in a remainder of 860.
Put 2 as the next digit of the answer. 
Result so far: 9802.0
Deduct 1722 from 2582 and we're left with 860.
Fetch the next digit (1) from the dividend, attach it to 860 and continue: 8601 / 861

Moving on to step 8:
When dividing 8601 by 861, we get 9 with a remainder of 852.
The next digit of our result is 9. 
Result so far: 98029.0
Subtract 7749 from 8601 to get 852.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8520, and continue the process.

Advancing to step 9:
861 can be fit into 8520 9 times, resulting in a remainder of 771.
Write down 9 as next digit of the result. 
Result so far: 98029.9
Subtract 7749 from 8520 to get 771.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7710, and continue the process.

Advancing to step 10:
The number 861 fits into 7710 8 times, leaving a remainder of 822.
Use 8 as the next digit of our solution. 
Result so far: 98029.98
If we subtract 6888 from 7710, we get 822.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8220, and continue the process.

On to step 11:
The number 861 fits into 8220 9 times, leaving a remainder of 471.
Write down 9 as next digit of the result. 
Result so far: 98029.989
Subtracting 7749 from 8220 leaves us with 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

Step 12:
861 goes into 4710 5 times with a remainder of 405.
The number 5 becomes the next digit in our result. 
Result so far: 98029.9895
Subtracting 4305 from 4710 leaves us with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

On to step 13:
When dividing 4050 by 861, we get 4 with a remainder of 606.
Record the quotient 4 as the next digit in the result. 
Result so far: 98029.98954
If we take 3444 away from 4050, we end up with 606.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

Advancing to step 14:
The number 861 fits into 6060 7 times, leaving a remainder of 33.
Use 7 as the next digit of our solution. 
Result so far: 98029.989547
The remainder is 33 after subtracting 6027 from 6060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 15:
861 can be fit into 330 0 times, resulting in a remainder of 330.
Use 0 as the next digit of our solution. 
Result so far: 98029.989547
Deduct 0 from 330 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Going ahead to step 16:
861 goes into 3300 3 times with a remainder of 717.
Write down 3 as next digit of the result. 
Result so far: 98029.98954703
If we take 2583 away from 3300, we end up with 717.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7170, and continue the process.

The final outcome is 98029.98954703, with a leftover of 7.17e-07.
