7858351 ÷ 942 
We're looking to find how many times 942 goes into 7858351.

Going ahead to step 1:
If we divide 7 by 942, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 942

Advancing to step 2:
78 divided by 942 is 0 with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Fetch the next digit (5) from the dividend, attach it to 78 and continue: 785 / 942

Advancing to step 3:
785 divided by 942 is 0 with a remainder of 785.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 785, we end up with 785.
Append the next digit (8) from the dividend to 785 and continue with: 7858 / 942

Going ahead to step 4:
If we divide 7858 by 942, we get 8 and a remainder of 322.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 7536 away from 7858, we end up with 322.
Bring next digit (3) of the dividend behind the 322 and repeat the process: 3223 / 942

Let's proceed to step 5:
942 can be fit into 3223 3 times, resulting in a remainder of 397.
Write down 3 as next digit of the result. 
Result so far: 83.0
The remainder is 397 after subtracting 2826 from 3223.
Fetch the next digit (5) from the dividend, attach it to 397 and continue: 3975 / 942

Going ahead to step 6:
When dividing 3975 by 942, we get 4 with a remainder of 207.
The number 4 becomes the next digit in our result. 
Result so far: 834.0
The remainder is 207 after subtracting 3768 from 3975.
Bring next digit (1) of the dividend behind the 207 and repeat the process: 2071 / 942

Going ahead to step 7:
If we divide 2071 by 942, we get 2 and a remainder of 187.
Write down 2 as next digit of the result. 
Result so far: 8342.0
Subtracting 1884 from 2071 leaves us with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Step 8:
The number 942 fits into 1870 1 times, leaving a remainder of 928.
Use 1 as the next digit of our solution. 
Result so far: 8342.1
The remainder is 928 after subtracting 942 from 1870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9280, and continue the process.

Going ahead to step 9:
If we divide 9280 by 942, we get 9 and a remainder of 802.
Record the quotient 9 as the next digit in the result. 
Result so far: 8342.19
Subtracting 8478 from 9280 leaves us with 802.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8020, and continue the process.

On to step 10:
If we divide 8020 by 942, we get 8 and a remainder of 484.
The number 8 becomes the next digit in our result. 
Result so far: 8342.198
Subtract 7536 from 8020 to get 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Let's proceed to step 11:
4840 divided by 942 is 5 with a remainder of 130.
Record the quotient 5 as the next digit in the result. 
Result so far: 8342.1985
Subtracting 4710 from 4840 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 12:
942 can be fit into 1300 1 times, resulting in a remainder of 358.
Write down 1 as next digit of the result. 
Result so far: 8342.19851
Subtracting 942 from 1300 leaves us with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Going ahead to step 13:
3580 divided by 942 is 3 with a remainder of 754.
The next digit of our result is 3. 
Result so far: 8342.198513
Subtract 2826 from 3580 to get 754.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7540, and continue the process.

On to step 14:
942 can be fit into 7540 8 times, resulting in a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 8342.1985138
Deduct 7536 from 7540 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 15:
942 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 8342.1985138
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 8342.1985138 with a remainder of 4e-08.
