86010698 ÷ 400 
Let's see how many times 400 fits into 86010698.

On to step 1:
When dividing 8 by 400, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 400

Moving on to step 2:
86 divided by 400 is 0 with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Take the next digit (0) from the dividend and append it to 86, then repeat: 860 / 400

On to step 3:
400 can be fit into 860 2 times, resulting in a remainder of 60.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 60 after subtracting 800 from 860.
Grab the next digit (1) from the dividend, add it to 60, then carry on: 601 / 400

Step 4:
400 goes into 601 1 times with a remainder of 201.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtracting 400 from 601 leaves us with 201.
Fetch the next digit (0) from the dividend, attach it to 201 and continue: 2010 / 400

Step 5:
2010 divided by 400 is 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 215.0
Subtract 2000 from 2010 to get 10.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 400

Step 6:
400 can be fit into 106 0 times, resulting in a remainder of 106.
The next digit of our result is 0. 
Result so far: 2150.0
Subtracting 0 from 106 leaves us with 106.
Include the next digit (9) from the dividend after 106, then repeat: 1069 / 400

Advancing to step 7:
The number 400 fits into 1069 2 times, leaving a remainder of 269.
Use 2 as the next digit of our solution. 
Result so far: 21502.0
If we take 800 away from 1069, we end up with 269.
Include the next digit (8) from the dividend after 269, then repeat: 2698 / 400

Step 8:
400 can be fit into 2698 6 times, resulting in a remainder of 298.
The number 6 becomes the next digit in our result. 
Result so far: 215026.0
Subtract 2400 from 2698 to get 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Going ahead to step 9:
400 can be fit into 2980 7 times, resulting in a remainder of 180.
Write down 7 as next digit of the result. 
Result so far: 215026.7
Subtracting 2800 from 2980 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 10:
The number 400 fits into 1800 4 times, leaving a remainder of 200.
Use 4 as the next digit of our solution. 
Result so far: 215026.74
Subtracting 1600 from 1800 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 11:
400 can be fit into 2000 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 215026.745
If we take 2000 away from 2000, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
When dividing 0 by 400, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 215026.745
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 13:
When dividing 0 by 400, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 215026.745
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 215026.745, and the remainder is 0.0.
