87429369 divided by 851 
We want to figure out the number of times 87429369 can be divided by 851.

Moving on to step 1:
851 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 851

Advancing to step 2:
When dividing 87 by 851, we get 0 with a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Take the next digit (4) from the dividend and append it to 87, then repeat: 874 / 851

On to step 3:
874 divided by 851 is 1 with a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 851 away from 874, we end up with 23.
Take the next digit (2) from the dividend and append it to 23, then repeat: 232 / 851

Moving on to step 4:
If we divide 232 by 851, we get 0 and a remainder of 232.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 232, we get 232.
Bring next digit (9) of the dividend behind the 232 and repeat the process: 2329 / 851

Step 5:
851 goes into 2329 2 times with a remainder of 627.
Record the quotient 2 as the next digit in the result. 
Result so far: 102.0
The remainder is 627 after subtracting 1702 from 2329.
Append the next digit (3) from the dividend to 627 and continue with: 6273 / 851

Advancing to step 6:
If we divide 6273 by 851, we get 7 and a remainder of 316.
Use 7 as the next digit of our solution. 
Result so far: 1027.0
If we take 5957 away from 6273, we end up with 316.
Fetch the next digit (6) from the dividend, attach it to 316 and continue: 3166 / 851

Let's proceed to step 7:
When dividing 3166 by 851, we get 3 with a remainder of 613.
The next digit of our result is 3. 
Result so far: 10273.0
The remainder is 613 after subtracting 2553 from 3166.
Take the next digit (9) from the dividend and append it to 613, then repeat: 6139 / 851

Going ahead to step 8:
The number 851 fits into 6139 7 times, leaving a remainder of 182.
The number 7 becomes the next digit in our result. 
Result so far: 102737.0
Deduct 5957 from 6139 and we're left with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Advancing to step 9:
When dividing 1820 by 851, we get 2 with a remainder of 118.
Record the quotient 2 as the next digit in the result. 
Result so far: 102737.2
The remainder is 118 after subtracting 1702 from 1820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Let's proceed to step 10:
851 can be fit into 1180 1 times, resulting in a remainder of 329.
Use 1 as the next digit of our solution. 
Result so far: 102737.21
If we take 851 away from 1180, we end up with 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Moving on to step 11:
851 can be fit into 3290 3 times, resulting in a remainder of 737.
Use 3 as the next digit of our solution. 
Result so far: 102737.213
The remainder is 737 after subtracting 2553 from 3290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7370, and continue the process.

Let's proceed to step 12:
The number 851 fits into 7370 8 times, leaving a remainder of 562.
Record the quotient 8 as the next digit in the result. 
Result so far: 102737.2138
Subtracting 6808 from 7370 leaves us with 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Let's proceed to step 13:
851 goes into 5620 6 times with a remainder of 514.
Use 6 as the next digit of our solution. 
Result so far: 102737.21386
The remainder is 514 after subtracting 5106 from 5620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Going ahead to step 14:
5140 divided by 851 is 6 with a remainder of 34.
The number 6 becomes the next digit in our result. 
Result so far: 102737.213866
Subtract 5106 from 5140 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

In conclusion, the division gives 102737.213866 with a balance of 3.4e-06.
