We're dividing 81561737 by 207 
Our goal is to divide 81561737 by 207.

Going ahead to step 1:
207 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 207

Let's proceed to step 2:
81 divided by 207 is 0 with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Append the next digit (5) from the dividend to 81 and continue with: 815 / 207

Let's proceed to step 3:
207 can be fit into 815 3 times, resulting in a remainder of 194.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 621 from 815 to get 194.
Grab the next digit (6) from the dividend, add it to 194, then carry on: 1946 / 207

Step 4:
1946 divided by 207 is 9 with a remainder of 83.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Subtracting 1863 from 1946 leaves us with 83.
Fetch the next digit (1) from the dividend, attach it to 83 and continue: 831 / 207

Step 5:
207 can be fit into 831 4 times, resulting in a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 394.0
Deduct 828 from 831 and we're left with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 207

Going ahead to step 6:
37 divided by 207 is 0 with a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 3940.0
If we take 0 away from 37, we end up with 37.
Fetch the next digit (3) from the dividend, attach it to 37 and continue: 373 / 207

On to step 7:
207 goes into 373 1 times with a remainder of 166.
The number 1 becomes the next digit in our result. 
Result so far: 39401.0
Deduct 207 from 373 and we're left with 166.
Bring next digit (7) of the dividend behind the 166 and repeat the process: 1667 / 207

Step 8:
207 can be fit into 1667 8 times, resulting in a remainder of 11.
Use 8 as the next digit of our solution. 
Result so far: 394018.0
If we subtract 1656 from 1667, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 9:
110 divided by 207 is 0 with a remainder of 110.
Put 0 as the next digit of the answer. 
Result so far: 394018.0
Subtracting 0 from 110 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 10:
The number 207 fits into 1100 5 times, leaving a remainder of 65.
The next digit of our result is 5. 
Result so far: 394018.05
If we subtract 1035 from 1100, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 11:
207 goes into 650 3 times with a remainder of 29.
Write down 3 as next digit of the result. 
Result so far: 394018.053
If we take 621 away from 650, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 12:
If we divide 290 by 207, we get 1 and a remainder of 83.
Write down 1 as next digit of the result. 
Result so far: 394018.0531
Subtract 207 from 290 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Moving on to step 13:
When dividing 830 by 207, we get 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 394018.05314
Deduct 828 from 830 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 14:
When dividing 20 by 207, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 394018.05314
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 15:
207 goes into 200 0 times with a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 394018.05314
Subtracting 0 from 200 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.

The final result is 394018.05314 with a remainder of 2e-06.
