85393470 ÷ 861 
We want to figure out the number of times 85393470 can be divided by 861.

Step 1:
The number 861 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 861

Moving on to step 2:
861 can be fit into 85 0 times, resulting in a remainder of 85.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Fetch the next digit (3) from the dividend, attach it to 85 and continue: 853 / 861

Moving on to step 3:
If we divide 853 by 861, we get 0 and a remainder of 853.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 853 after subtracting 0 from 853.
Append the next digit (9) from the dividend to 853 and continue with: 8539 / 861

Let's proceed to step 4:
The number 861 fits into 8539 9 times, leaving a remainder of 790.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 790 after subtracting 7749 from 8539.
Include the next digit (3) from the dividend after 790, then repeat: 7903 / 861

Going ahead to step 5:
When dividing 7903 by 861, we get 9 with a remainder of 154.
The next digit of our result is 9. 
Result so far: 99.0
The remainder is 154 after subtracting 7749 from 7903.
Append the next digit (4) from the dividend to 154 and continue with: 1544 / 861

Moving on to step 6:
1544 divided by 861 is 1 with a remainder of 683.
Use 1 as the next digit of our solution. 
Result so far: 991.0
If we subtract 861 from 1544, we get 683.
Include the next digit (7) from the dividend after 683, then repeat: 6837 / 861

Advancing to step 7:
6837 divided by 861 is 7 with a remainder of 810.
Record the quotient 7 as the next digit in the result. 
Result so far: 9917.0
Subtract 6027 from 6837 to get 810.
Grab the next digit (0) from the dividend, add it to 810, then carry on: 8100 / 861

On to step 8:
861 goes into 8100 9 times with a remainder of 351.
Put 9 as the next digit of the answer. 
Result so far: 99179.0
If we take 7749 away from 8100, we end up with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Moving on to step 9:
3510 divided by 861 is 4 with a remainder of 66.
Put 4 as the next digit of the answer. 
Result so far: 99179.4
The remainder is 66 after subtracting 3444 from 3510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 10:
660 divided by 861 is 0 with a remainder of 660.
The number 0 becomes the next digit in our result. 
Result so far: 99179.4
Deduct 0 from 660 and we're left with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Step 11:
When dividing 6600 by 861, we get 7 with a remainder of 573.
Put 7 as the next digit of the answer. 
Result so far: 99179.407
Subtract 6027 from 6600 to get 573.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5730, and continue the process.

Let's proceed to step 12:
861 goes into 5730 6 times with a remainder of 564.
Write down 6 as next digit of the result. 
Result so far: 99179.4076
The remainder is 564 after subtracting 5166 from 5730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Advancing to step 13:
861 goes into 5640 6 times with a remainder of 474.
Record the quotient 6 as the next digit in the result. 
Result so far: 99179.40766
Subtract 5166 from 5640 to get 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

In conclusion, the division gives 99179.40766 with a balance of 0.000474.
