60309988 ÷ 857 
We're looking to find how many times 857 goes into 60309988.

Step 1:
When dividing 6 by 857, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 857

On to step 2:
When dividing 60 by 857, we get 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 60 leaves us with 60.
Fetch the next digit (3) from the dividend, attach it to 60 and continue: 603 / 857

Step 3:
857 can be fit into 603 0 times, resulting in a remainder of 603.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 603 leaves us with 603.
Grab the next digit (0) from the dividend, add it to 603, then carry on: 6030 / 857

Advancing to step 4:
857 can be fit into 6030 7 times, resulting in a remainder of 31.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 5999 from 6030 to get 31.
Include the next digit (9) from the dividend after 31, then repeat: 319 / 857

On to step 5:
The number 857 fits into 319 0 times, leaving a remainder of 319.
Put 0 as the next digit of the answer. 
Result so far: 70.0
Deduct 0 from 319 and we're left with 319.
Bring next digit (9) of the dividend behind the 319 and repeat the process: 3199 / 857

Moving on to step 6:
3199 divided by 857 is 3 with a remainder of 628.
Put 3 as the next digit of the answer. 
Result so far: 703.0
Subtract 2571 from 3199 to get 628.
Grab the next digit (8) from the dividend, add it to 628, then carry on: 6288 / 857

Moving on to step 7:
857 goes into 6288 7 times with a remainder of 289.
The next digit of our result is 7. 
Result so far: 7037.0
Subtract 5999 from 6288 to get 289.
Take the next digit (8) from the dividend and append it to 289, then repeat: 2898 / 857

Step 8:
The number 857 fits into 2898 3 times, leaving a remainder of 327.
The number 3 becomes the next digit in our result. 
Result so far: 70373.0
Subtracting 2571 from 2898 leaves us with 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Advancing to step 9:
857 can be fit into 3270 3 times, resulting in a remainder of 699.
Write down 3 as next digit of the result. 
Result so far: 70373.3
Subtracting 2571 from 3270 leaves us with 699.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6990, and continue the process.

Going ahead to step 10:
6990 divided by 857 is 8 with a remainder of 134.
Write down 8 as next digit of the result. 
Result so far: 70373.38
Subtract 6856 from 6990 to get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Advancing to step 11:
857 can be fit into 1340 1 times, resulting in a remainder of 483.
Put 1 as the next digit of the answer. 
Result so far: 70373.381
The remainder is 483 after subtracting 857 from 1340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

Moving on to step 12:
857 goes into 4830 5 times with a remainder of 545.
Write down 5 as next digit of the result. 
Result so far: 70373.3815
If we take 4285 away from 4830, we end up with 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

Step 13:
857 goes into 5450 6 times with a remainder of 308.
Use 6 as the next digit of our solution. 
Result so far: 70373.38156
Subtract 5142 from 5450 to get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Step 14:
The number 857 fits into 3080 3 times, leaving a remainder of 509.
Write down 3 as next digit of the result. 
Result so far: 70373.381563
Deduct 2571 from 3080 and we're left with 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

Advancing to step 15:
The number 857 fits into 5090 5 times, leaving a remainder of 805.
The next digit of our result is 5. 
Result so far: 70373.3815635
The remainder is 805 after subtracting 4285 from 5090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8050, and continue the process.

On to step 16:
857 can be fit into 8050 9 times, resulting in a remainder of 337.
The next digit of our result is 9. 
Result so far: 70373.38156359
Deduct 7713 from 8050 and we're left with 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

The final outcome is 70373.38156359, with a leftover of 3.37e-07.
