Let's divide 86751991 by 149
We want to figure out the number of times 86751991 can be divided by 149.

Advancing to step 1:
8 divided by 149 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 149

On to step 2:
86 divided by 149 is 0 with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Grab the next digit (7) from the dividend, add it to 86, then carry on: 867 / 149

Going ahead to step 3:
If we divide 867 by 149, we get 5 and a remainder of 122.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 745 from 867, we get 122.
Take the next digit (5) from the dividend and append it to 122, then repeat: 1225 / 149

Step 4:
When dividing 1225 by 149, we get 8 with a remainder of 33.
Write down 8 as next digit of the result. 
Result so far: 58.0
The remainder is 33 after subtracting 1192 from 1225.
Append the next digit (1) from the dividend to 33 and continue with: 331 / 149

On to step 5:
149 goes into 331 2 times with a remainder of 33.
Write down 2 as next digit of the result. 
Result so far: 582.0
The remainder is 33 after subtracting 298 from 331.
Grab the next digit (9) from the dividend, add it to 33, then carry on: 339 / 149

Going ahead to step 6:
The number 149 fits into 339 2 times, leaving a remainder of 41.
Write down 2 as next digit of the result. 
Result so far: 5822.0
If we take 298 away from 339, we end up with 41.
Fetch the next digit (9) from the dividend, attach it to 41 and continue: 419 / 149

Going ahead to step 7:
When dividing 419 by 149, we get 2 with a remainder of 121.
The number 2 becomes the next digit in our result. 
Result so far: 58222.0
If we take 298 away from 419, we end up with 121.
Fetch the next digit (1) from the dividend, attach it to 121 and continue: 1211 / 149

Moving on to step 8:
The number 149 fits into 1211 8 times, leaving a remainder of 19.
Write down 8 as next digit of the result. 
Result so far: 582228.0
If we subtract 1192 from 1211, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 9:
190 divided by 149 is 1 with a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 582228.1
Subtract 149 from 190 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.

Moving on to step 10:
The number 149 fits into 410 2 times, leaving a remainder of 112.
Use 2 as the next digit of our solution. 
Result so far: 582228.12
If we take 298 away from 410, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 11:
The number 149 fits into 1120 7 times, leaving a remainder of 77.
Put 7 as the next digit of the answer. 
Result so far: 582228.127
If we take 1043 away from 1120, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 12:
149 goes into 770 5 times with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 582228.1275
Subtracting 745 from 770 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 13:
When dividing 250 by 149, we get 1 with a remainder of 101.
Record the quotient 1 as the next digit in the result. 
Result so far: 582228.12751
Deduct 149 from 250 and we're left with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Advancing to step 14:
The number 149 fits into 1010 6 times, leaving a remainder of 116.
The next digit of our result is 6. 
Result so far: 582228.127516
Subtract 894 from 1010 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Step 15:
When dividing 1160 by 149, we get 7 with a remainder of 117.
Write down 7 as next digit of the result. 
Result so far: 582228.1275167
If we take 1043 away from 1160, we end up with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Going ahead to step 16:
If we divide 1170 by 149, we get 7 and a remainder of 127.
The next digit of our result is 7. 
Result so far: 582228.12751677
Subtracting 1043 from 1170 leaves us with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

The quotient of the division is 582228.12751677, and the remainder is 1.27e-07.
