Let's divide 83915041 by 670
Let's see how many times 670 fits into 83915041.

Advancing to step 1:
8 divided by 670 is 0 with 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.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 670

On to step 2:
670 goes into 83 0 times with a remainder of 83.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Append the next digit (9) from the dividend to 83 and continue with: 839 / 670

Step 3:
670 can be fit into 839 1 times, resulting in a remainder of 169.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 670 from 839, we get 169.
Bring next digit (1) of the dividend behind the 169 and repeat the process: 1691 / 670

Step 4:
670 goes into 1691 2 times with a remainder of 351.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 1340 away from 1691, we end up with 351.
Include the next digit (5) from the dividend after 351, then repeat: 3515 / 670

Step 5:
If we divide 3515 by 670, we get 5 and a remainder of 165.
Put 5 as the next digit of the answer. 
Result so far: 125.0
The remainder is 165 after subtracting 3350 from 3515.
Fetch the next digit (0) from the dividend, attach it to 165 and continue: 1650 / 670

On to step 6:
1650 divided by 670 is 2 with a remainder of 310.
Use 2 as the next digit of our solution. 
Result so far: 1252.0
If we subtract 1340 from 1650, we get 310.
Fetch the next digit (4) from the dividend, attach it to 310 and continue: 3104 / 670

Step 7:
If we divide 3104 by 670, we get 4 and a remainder of 424.
Write down 4 as next digit of the result. 
Result so far: 12524.0
If we subtract 2680 from 3104, we get 424.
Grab the next digit (1) from the dividend, add it to 424, then carry on: 4241 / 670

On to step 8:
670 goes into 4241 6 times with a remainder of 221.
The number 6 becomes the next digit in our result. 
Result so far: 125246.0
Subtracting 4020 from 4241 leaves us with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Step 9:
670 goes into 2210 3 times with a remainder of 200.
The number 3 becomes the next digit in our result. 
Result so far: 125246.3
Deduct 2010 from 2210 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 10:
670 can be fit into 2000 2 times, resulting in a remainder of 660.
The number 2 becomes the next digit in our result. 
Result so far: 125246.32
The remainder is 660 after subtracting 1340 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

On to step 11:
If we divide 6600 by 670, we get 9 and a remainder of 570.
Record the quotient 9 as the next digit in the result. 
Result so far: 125246.329
If we take 6030 away from 6600, we end up with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Moving on to step 12:
When dividing 5700 by 670, we get 8 with a remainder of 340.
Use 8 as the next digit of our solution. 
Result so far: 125246.3298
Subtracting 5360 from 5700 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 13:
If we divide 3400 by 670, we get 5 and a remainder of 50.
The next digit of our result is 5. 
Result so far: 125246.32985
If we take 3350 away from 3400, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 14:
500 divided by 670 is 0 with a remainder of 500.
The next digit of our result is 0. 
Result so far: 125246.32985
Subtracting 0 from 500 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Going ahead to step 15:
The number 670 fits into 5000 7 times, leaving a remainder of 310.
The next digit of our result is 7. 
Result so far: 125246.3298507
Deduct 4690 from 5000 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 16:
The number 670 fits into 3100 4 times, leaving a remainder of 420.
Put 4 as the next digit of the answer. 
Result so far: 125246.32985074
The remainder is 420 after subtracting 2680 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

The final outcome is 125246.32985074, with a leftover of 4.2e-07.
