86672178 ÷ 131 
We want to divide 86672178 by 131.

Going ahead to step 1:
If we divide 8 by 131, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 131

Advancing to step 2:
The number 131 fits into 86 0 times, leaving a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Take the next digit (6) from the dividend and append it to 86, then repeat: 866 / 131

Advancing to step 3:
If we divide 866 by 131, we get 6 and a remainder of 80.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 80 after subtracting 786 from 866.
Take the next digit (7) from the dividend and append it to 80, then repeat: 807 / 131

On to step 4:
131 can be fit into 807 6 times, resulting in a remainder of 21.
The next digit of our result is 6. 
Result so far: 66.0
If we take 786 away from 807, we end up with 21.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 131

Moving on to step 5:
131 goes into 212 1 times with a remainder of 81.
The number 1 becomes the next digit in our result. 
Result so far: 661.0
Subtracting 131 from 212 leaves us with 81.
Take the next digit (1) from the dividend and append it to 81, then repeat: 811 / 131

On to step 6:
131 can be fit into 811 6 times, resulting in a remainder of 25.
Use 6 as the next digit of our solution. 
Result so far: 6616.0
If we subtract 786 from 811, we get 25.
Bring next digit (7) of the dividend behind the 25 and repeat the process: 257 / 131

Moving on to step 7:
When dividing 257 by 131, we get 1 with a remainder of 126.
The number 1 becomes the next digit in our result. 
Result so far: 66161.0
Deduct 131 from 257 and we're left with 126.
Fetch the next digit (8) from the dividend, attach it to 126 and continue: 1268 / 131

Step 8:
If we divide 1268 by 131, we get 9 and a remainder of 89.
The next digit of our result is 9. 
Result so far: 661619.0
Deduct 1179 from 1268 and we're left with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Advancing to step 9:
The number 131 fits into 890 6 times, leaving a remainder of 104.
Put 6 as the next digit of the answer. 
Result so far: 661619.6
If we subtract 786 from 890, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 10:
131 goes into 1040 7 times with a remainder of 123.
The next digit of our result is 7. 
Result so far: 661619.67
If we subtract 917 from 1040, we get 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Going ahead to step 11:
1230 divided by 131 is 9 with a remainder of 51.
The next digit of our result is 9. 
Result so far: 661619.679
Subtract 1179 from 1230 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 12:
When dividing 510 by 131, we get 3 with a remainder of 117.
Use 3 as the next digit of our solution. 
Result so far: 661619.6793
If we subtract 393 from 510, we get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Advancing to step 13:
131 goes into 1170 8 times with a remainder of 122.
Write down 8 as next digit of the result. 
Result so far: 661619.67938
Subtracting 1048 from 1170 leaves us with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Moving on to step 14:
When dividing 1220 by 131, we get 9 with a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 661619.679389
Subtract 1179 from 1220 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 15:
131 goes into 410 3 times with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 661619.6793893
If we subtract 393 from 410, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 16:
When dividing 170 by 131, we get 1 with a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 661619.67938931
Subtract 131 from 170 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Our division results in 661619.67938931 with a remaining 3.9e-08.
