We divide 85570377 by 561
We want to figure out the number of times 85570377 can be divided by 561.

On to step 1:
8 divided by 561 is 0 with 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.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 561

Step 2:
561 can be fit into 85 0 times, resulting in a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 85 and we're left with 85.
Bring next digit (5) of the dividend behind the 85 and repeat the process: 855 / 561

Let's proceed to step 3:
855 divided by 561 is 1 with a remainder of 294.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 561 from 855 leaves us with 294.
Grab the next digit (7) from the dividend, add it to 294, then carry on: 2947 / 561

Advancing to step 4:
The number 561 fits into 2947 5 times, leaving a remainder of 142.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 2805 from 2947 and we're left with 142.
Grab the next digit (0) from the dividend, add it to 142, then carry on: 1420 / 561

Advancing to step 5:
If we divide 1420 by 561, we get 2 and a remainder of 298.
Record the quotient 2 as the next digit in the result. 
Result so far: 152.0
If we take 1122 away from 1420, we end up with 298.
Include the next digit (3) from the dividend after 298, then repeat: 2983 / 561

Going ahead to step 6:
When dividing 2983 by 561, we get 5 with a remainder of 178.
Record the quotient 5 as the next digit in the result. 
Result so far: 1525.0
Subtracting 2805 from 2983 leaves us with 178.
Include the next digit (7) from the dividend after 178, then repeat: 1787 / 561

Moving on to step 7:
If we divide 1787 by 561, we get 3 and a remainder of 104.
The next digit of our result is 3. 
Result so far: 15253.0
Deduct 1683 from 1787 and we're left with 104.
Bring next digit (7) of the dividend behind the 104 and repeat the process: 1047 / 561

Moving on to step 8:
If we divide 1047 by 561, we get 1 and a remainder of 486.
The number 1 becomes the next digit in our result. 
Result so far: 152531.0
Subtracting 561 from 1047 leaves us with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Going ahead to step 9:
If we divide 4860 by 561, we get 8 and a remainder of 372.
The next digit of our result is 8. 
Result so far: 152531.8
Deduct 4488 from 4860 and we're left with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Going ahead to step 10:
If we divide 3720 by 561, we get 6 and a remainder of 354.
The next digit of our result is 6. 
Result so far: 152531.86
Subtract 3366 from 3720 to get 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Going ahead to step 11:
When dividing 3540 by 561, we get 6 with a remainder of 174.
Write down 6 as next digit of the result. 
Result so far: 152531.866
If we subtract 3366 from 3540, we get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

After the division, we end up with 152531.866 and a remainder of 0.0174.
