87666712 ÷ 694 
We want to divide 87666712 by 694.

On to step 1:
When dividing 8 by 694, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 694

Advancing to step 2:
694 goes into 87 0 times with a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Grab the next digit (6) from the dividend, add it to 87, then carry on: 876 / 694

Let's proceed to step 3:
The number 694 fits into 876 1 times, leaving a remainder of 182.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 694 from 876 leaves us with 182.
Bring next digit (6) of the dividend behind the 182 and repeat the process: 1826 / 694

Step 4:
694 can be fit into 1826 2 times, resulting in a remainder of 438.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 438 after subtracting 1388 from 1826.
Take the next digit (6) from the dividend and append it to 438, then repeat: 4386 / 694

On to step 5:
The number 694 fits into 4386 6 times, leaving a remainder of 222.
Record the quotient 6 as the next digit in the result. 
Result so far: 126.0
Subtracting 4164 from 4386 leaves us with 222.
Bring next digit (7) of the dividend behind the 222 and repeat the process: 2227 / 694

Advancing to step 6:
2227 divided by 694 is 3 with a remainder of 145.
The number 3 becomes the next digit in our result. 
Result so far: 1263.0
Subtracting 2082 from 2227 leaves us with 145.
Fetch the next digit (1) from the dividend, attach it to 145 and continue: 1451 / 694

Let's proceed to step 7:
If we divide 1451 by 694, we get 2 and a remainder of 63.
Put 2 as the next digit of the answer. 
Result so far: 12632.0
Subtract 1388 from 1451 to get 63.
Take the next digit (2) from the dividend and append it to 63, then repeat: 632 / 694

Advancing to step 8:
When dividing 632 by 694, we get 0 with a remainder of 632.
Write down 0 as next digit of the result. 
Result so far: 126320.0
Deduct 0 from 632 and we're left with 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Let's proceed to step 9:
694 can be fit into 6320 9 times, resulting in a remainder of 74.
Write down 9 as next digit of the result. 
Result so far: 126320.9
Deduct 6246 from 6320 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 10:
694 can be fit into 740 1 times, resulting in a remainder of 46.
Put 1 as the next digit of the answer. 
Result so far: 126320.91
If we take 694 away from 740, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 11:
When dividing 460 by 694, we get 0 with a remainder of 460.
The next digit of our result is 0. 
Result so far: 126320.91
Subtracting 0 from 460 leaves us with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Moving on to step 12:
When dividing 4600 by 694, we get 6 with a remainder of 436.
The next digit of our result is 6. 
Result so far: 126320.9106
Subtract 4164 from 4600 to get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

On to step 13:
694 goes into 4360 6 times with a remainder of 196.
Use 6 as the next digit of our solution. 
Result so far: 126320.91066
Deduct 4164 from 4360 and we're left with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

The final outcome is 126320.91066, with a leftover of 0.000196.
